Description:FIELD OF THE INVENTION

[0001] The present invention relates to an autonomous tool maintenance and management device that facilitates automated assessment, upkeep, and organization of tools and equipment, particularly in industrial, mechanical, and technical environments, requiring efficient maintenance operations.

BACKGROUND OF THE INVENTION

[0002] In various industrial, mechanical, and technical settings, the upkeep and readiness of tools and equipment are essential for maintaining workflow efficiency, safety, and precision. Routine maintenance tasks such as inspection, sharpening, alignment, and cleaning are critical but often time-consuming, labor-intensive, and prone to inconsistency when performed manually. The increasing complexity of tools and the demand for high operational reliability further necessitate advanced devices capable of not only managing but also diagnosing tool conditions effectively. Manual approaches often lead to delays, tool damage, inaccurate maintenance, and resource inefficiencies, which collectively affect productivity and safety in the workplace. Additionally, improper storage and lack of lubrication can degrade tool quality over time, while human error during maintenance operations can lead to costly failures or downtime.

[0003] Traditionally, tool maintenance and management tasks have relied on skilled human operators using standalone stations for specific operations such as sharpening, screwing, or sanding. These processes often involve repetitive manual inspections and trial-based interventions that lack consistency and measurable accuracy. Storage devices are usually non-intelligent, requiring manual sorting and inventory checks, which increases the chances of tool misplacement or oversight in preventive maintenance. The absence of centralized, intelligent control and feedback mechanisms makes it difficult to monitor tool conditions in real time or adapt maintenance procedures dynamically. Moreover, voice-guided interaction or visual assistance has rarely been integrated into traditional devices, further limiting their usability in fast-paced or remote environments.

[0004] US8812154B2 discloses an apparatus that may comprise a number of mobile robotic machines, a wireless communications system and a computer system. The number of mobile robotic machines may be capable of moving to a number of locations in a maintenance area and may be capable of performing a number of maintenance operations on a structure in the maintenance area. The wireless communications system may be capable of providing communication with the number of mobile robotic machines within the maintenance area. The computer system may be capable of exchanging information with the number of mobile robotic machines using the wireless communications system.

[0005] US8597083B2 discloses a blade sharpening system using the interior surface of a grinding wheel against which a blade is drawn along its entire length for sharpening. The sharpening system includes a blade holding configuration having multiple hinged arms. A cam operating between two of the hinged arms serves to alter the angle of incidence between the blade and the grinding wheel as the blade is drawn across the grinding wheel. The result is that a wide variety of different blade configurations can be easily accommodated by the sharpening system.

[0006] Conventionally, many devices used for tool maintenance and management rely heavily on manual processes, leading to inconsistencies, time inefficiencies, and increased dependency on skilled labour. These existing devices often lack intelligent coordination, automated decision-making, and integrated handling, making them unsuitable for high-demand environments requiring precision, speed, and real-time responsiveness.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to autonomously manage, maintain, and organize tools with minimal human intervention, while ensuring consistency, operational efficiency, and intelligent decision-making suitable for dynamic industrial and technical environments.

[0021] The present invention relates to an autonomous tool maintenance and management device that is capable of performing automated inspection, servicing, handling, and organized storage of tools and equipment with minimal human intervention.

[0022] Referring to Figure 1 and 2, an isometric view of an autonomous tool maintenance and management device and an isometric view of a platform associated with the device are illustrated, respectively, comprising a housing 101 supported on extendable legs 102 terminating in motorized omnidirectional wheels 103, an inlet 104 arranged on the housing 101 and equipped with a motorized sliding gate 105, a conveyor belt 106 disposed within the housing 101 with a U-shaped sensor-integrated frame 107 positioned above, a motorized two-axis guiding rail 108 mounted inside the housing 101 supporting a pneumatic linkage 109 ending in a first ball-and-socket gripping unit 110, a motorized plate 201 rotatably mounted on a maintenance platform 111 and equipped with adjustable suction cups 202 and gripping clamps 203, a sharpening module 204 mounted on the platform 111 comprising a vertical bar 204a and a horizontally affixed flap 204b, a motorized semi-circular slider 204c mounted on a bottom portion of the flap 204b, an articulating pneumatic pin 204d holding a whetstone 204e via a second ball-and-socket joint 204f couple to the slider 204c.

[0023] Figure 1 and 2 further illustrates a maintenance module 205 includes a grip-and-twist arrangement 205a operably connected to a mechanical linkage 205b, a high-resolution camera 205c integrated on the platform 111, a handle sanding module 206 comprises of a vertical rod 206a attached to a motorized sliding unit 206b mounted on the platform 111, a C-shaped sanding member 206c connected to the sliding unit 206b via a third motorized ball-and-socket joint 206d, an abrasive sheet 206e mounted along the inner surface of the member 206c, a storage and lubrication module 112 comprising a storage vessel 112a divided into multiple compartment installed inside the housing 101, a suction hose 112b containing a dispensing nozzle 112c at the hose 112b tip connected to the vessel 112a, a microphone 113 integrated in the housing 101, a holographic projection unit 114 configure with the housing 101, the housing 101 includes multiple designated compartments 115 for storing tool/equipment.

[0024] The device disclosed herein comprises of a housing 101 configured for receiving, storing, and maintaining multiple tools and equipment. The housing 101 is constructed from high-strength aluminum alloy and reinforced polymer composites, internally compartmentalized with insulated partitions to support modules, protect electronics, and ensure structural stability during tool maintenance operations. A multiple extendable legs 102 installed underneath of the housing 101 and are internally actuated by a hydraulic unit comprising miniature cylinders controlled by a microcontroller. When activated by the microcontroller, pressurized fluid extends or retracts the legs 102 to adjust height or stability. Each leg includes telescopic segments with locking grooves, enabling smooth vertical motion and firm positioning on uneven surfaces.

[0025] Each extendable legs 102 are supported by motorized omnidirectional wheels 103 for maneuvering over a fixed surface. The omnidirectional wheels 103 consist of a central motorized hub integrated with multiple peripheral rollers mounted at 45-degree angles. Each roller is independently rotatable, allowing movement in any direction without changing the wheel's orientation. The central motor provides rotational force, while microcontroller-coordinated signals control the speed and direction of each roller. This configuration enables precise manoeuvring, such as sideways drift, diagonal motion, and zero-radius turns. Encoders and gyroscopic sensors monitor wheel position and orientation, ensuring stable, adaptive movement across complex floor terrains.

[0026] An inlet 104 arranged on the housing 101 and equipped with a motorized sliding gate 105 for placement and retrieval of tool/equipment into the housing 101. The inlet 104 is a reinforced opening on the housing 101, framed with shock-absorbent lining to safely receive tools. The motorized sliding gate 105 is driven by a linear actuator connected to a DC gear motor, controlled by the microcontroller. When a tool is detected near the inlet 104 using a proximity sensor, the microcontroller activates the motor, causing the gate 105 to retract vertically via a guided rail. Limit switches determine the gate’s fully open and closed positions, while an optical sensor confirms safe tool placement before reclosed.

[0027] After opening of the housing 101, the microcontroller actuates a conveyor belt 106 disposed within the housing 101 for transporting tool/equipment. The conveyor belt 106 is composed of a durable, anti-slip rubberized material looped over two motorized rollers, forming a continuous transport surface within the housing 101. A DC motor coupled with a gearbox drives the rollers, enabling smooth, controlled movement of tools. The belt's speed and direction are regulated by the microcontroller based on sensor inputs from a U-shaped sensor-integrated frame 107. Tensioning pulleys maintain proper alignment and tension, while embedded load sensors detect tool presence and weight, allowing the conveyor belt 106 to adapt movement for safe tool handling.

[0028] The U-shaped sensor-integrated frame 107 positioned above the conveyor belt 106 for assessing structural integrity, sharpness, wear, and functionality. The frame 107 comprises of an optical sensor, an IR (Infrared) sensor, and an edge detection sensor. The optical sensor uses a high-resolution CMOS (Complementary Metal-Oxide-Semiconductor) imaging unit paired with an LED (Light Emitting Diode) illumination array to visually scan tools as they pass beneath. It captures detailed surface textures, wear marks, and geometric outlines in real time. The image data is transmitted to the microcontroller for pattern analysis and anomaly detection.

[0029] The infrared (IR) sensor operates by emitting controlled IR beams onto the surface of the tool and detecting the reflected signals through a photodiode receiver. Differences in thermal signature or reflectivity allow the sensor to estimate material consistency, surface heat, or embedded flaws like cracks. The IR sensor works in tandem with the optical sensor, providing complementary data where visual feedback is insufficient, such as in low-light conditions or internal defects, thereby enhancing diagnostic accuracy and maintenance decision-making.

[0030] The edge detection sensor utilizes a laser line projector and a phototransistor array to trace the perimeter or contour of the tool as it moves along the conveyor belt 106. Any deviation in expected shape, such as chips, bends, or uneven sharpening, is flagged. This data is cross-referenced with inputs from the optical and IR sensors by the microcontroller to confirm the issue and determine corrective action. The synergy among all three sensors ensures precise, multi-layered analysis before activating any modules for further operation.

[0031] A motorized two-axis guiding rail 108 mounted inside the housing 101 supporting a pneumatic linkage 109 ending in a first ball-and-socket gripping unit 110 for picking, holding, and relocating the tool/equipment. The motorized two-axis guiding rail 108 comprises an X-Y track means with linear actuators and stepper motors enabling horizontal and vertical movement inside the housing 101. The first axis allows lateral motion along the width of the platform 111, while the second provides forward-backward travel. The pneumatic linkage 109 with the gripping unit 110 is mounted on a sliding carriage that moves along both axes. The microcontroller coordinates motor input based on tool location detected by sensors, ensuring accurate positioning of the gripping unit 110 for pickup, relocation, or alignment.

[0032] The pneumatic linkage 109 operated by a pneumatic unit consists of articulated arm powered by compact pneumatic cylinders that extend or contract based on compressed air input regulated by solenoid valves. Controlled by the microcontroller, the microcontroller adjusts arm length and angle to position the attached gripping unit 110 precisely. The linkage 109 enables smooth, vibration-free motion, ideal for delicate tools. Pressure sensors ensure safe force application, while a rotary joint at the end allows rotation and angular adjustment, seamlessly coordinating with the first ball-and-socket gripping unit 110 for multi-directional tool handling.

[0033] The first ball-and-socket gripping unit 110, mounted at the end of the pneumatic linkage 109, features a hemispherical joint allowing 360° rotation and multi-axis tilting for flexible tool alignment. It houses a servo-actuated claws with adjustable gripping fingers lined with high-friction silicone pads to accommodate various tool shapes and sizes securely. Integrated force and proximity sensors continuously monitor grip pressure and object presence, preventing over-tightening or slippage. The microcontroller governs gripping actions based on sensor feedback and positional data from the guiding rail 108, ensuring stable, adaptive, and damage-free tool manipulation.

[0034] Once the tool/equipment passed through the U-shaped sensor-integrated frame 107, the first ball-and-socket gripping unit 110 grab it and accommodate it on a motorized plate 201. The motorized plate 201 rotatably mounted on a maintenance platform 111 located with the housing 101 and equipped with adjustable suction cups 202 and gripping clamps 203 for securing the tool/equipment during repair and alignment. The plate 201 driven by a stepper motor coupled with a precision gearbox for controlled rotation. The plate 201 is equipped with rotary encoders to track its angular position in real time. It serves as a dynamic base for aligning tools during repair, enabling optimal orientation for sharpening, screwing, or sanding. The microcontroller regulates plate 201 rotation based on input from various sensors and module requirements, ensuring accurate positioning and seamless transition between maintenance operations.

[0035] The suction cups 202 and gripping clamps 203 are integrated onto the motorized plate 201 to secure tools during maintenance. The suction cups 202 operate using a vacuum pump controlled by solenoid valves; when activated by the microcontroller, the pump creates negative pressure, allowing the cups 202 to firmly adhere to smooth tool surfaces. The gripping clamps 203 use miniature servo motors to open and close around irregular or textured tool parts. The gripping clamps 203 are integrated with pressure and proximity sensors to enable safe, precise, and adaptive handling of tool/equipment.

[0036] The proximity sensor, detects the presence and distance of a tool surface without physical contact. When a tool approaches within a set range, the sensor generates an electromagnetic field disturbance, which is interpreted as proximity. This signal is used to activate the clamp only when a tool is properly positioned, minimizing empty actuation, improving precision, and ensuring reliable alignment before gripping is initiated.

[0037] While, the pressure sensor integrated into the gripping clamps 203 consists of a piezoresistive membrane that detects the amount of force exerted when the clamps 203 engage a tool. As the clamp applies force, the membrane deforms slightly, causing a change in electrical resistance. This change is converted into a digital signal and sent to the microcontroller. The microcontroller uses this data to regulate the clamp’s motor, preventing excessive force that could damage delicate tools and ensuring a secure but safe grip.

[0038] Based on the data from the optical and edge detection sensor from the frame 107, if tool has a blade or cutting-edge showing signs of deformation, surface damage, or alignment deviations, the microcontroller actuates a sharpening module 204 arranged on the platform 111 to precisely sharpen blades of the tool/equipment. The sharpening module 204 includes a vertical bae and a horizontally affixed flap 204b configured to structurally support the sharpening means. The vertical base provides rigid structural support, while the horizontally affixed flap 204b is mounted using reinforced hinges, allowing stable lateral extension to securely anchor and align sharpening components during operation.

[0039] Further, a motorized semi-circular slider 204c mounted on a bottom portion of the flap 204b and consists of a curved rail embedded with a toothed track. A geared DC motor engages this track via a pinion gear, enabling smooth sliding motion along the semi-circular path. The microcontroller regulates motor speed and direction to position the sharpening element precisely at various angles. Rotary encoders track the slider’s position in real time, allowing adaptive angle adjustment based on the tool/equipment profile and sharpening requirements.

[0040] An articulating pneumatic pin 204d coupled to the slider 204c and it is a jointed actuator powered by a miniature hydraulic unit that pressurizes fluid to move internal pistons within the pin 204d. Controlled by solenoid valves and governed by the microcontroller, the hydraulic pressure allows the pin 204d to extend, retract, or bend at its joints for flexible articulation. This enables precise multi-angle positioning of a whetstone 204e via a second ball-and-socket joint 204f to allow multi-axis adjustment during sharpening. Integrated position sensors and flow regulators ensure smooth, stable motion, allowing the whetstone 204e to conform to varying tool/equipment geometries without causing damage.

[0041] The second ball-and-socket joint 204f connects the articulating pneumatic pin 204d to the sharpening module 204, allowing multi-axis rotational freedom. The joint 204f consists a ball component, typically made of hardened steel or polymer composite, fits snugly within a lubricated socket lined with low-friction material. Micro-servo motors and positional encoders within the socket regulate angular movement, enabling precise orientation of the attached whetstone 204e. The microcontroller coordinates movement based on tool profile data, ensuring consistent sharpening angles and stable contact. Internal dampers minimize vibration, allowing controlled, smooth articulation during operation.

[0042] The whetstone 204e is a high-grit abrasive block mounted on the second ball-and-socket joint 204f for sharpening tool/equipment edges. It is composed of industrial-grade ceramic or silicon carbide, enabling efficient material removal. As it contacts the tool/equipment, sensors monitor sharpening angle, force, and duration. The whetstone’s surface is periodically realigned or replaced to maintain uniform abrasive contact, ensuring precise and even tool/equipment’s blade sharpening.

[0043] A plurality of sensors comprising edge detection sensors, angle encoders, and force sensors to monitor whetstone 204e position, sharpening angle, and applied pressure, thereby enabling them to maintain optimal sharpness while prevention over-grinding. The edge detection sensors continuously detect the edges of the tool/equipment, internally operates similar as disclosed in the frame 107. The angle encoder is a rotary position sensor that uses either optical or magnetic principles to detect the angular displacement of rotating components, such as the sharpening joint. It converts angular motion into electrical signals using coded disks or magnetic fields, which the microcontroller interprets to maintain precise sharpening angles during operation.

[0044] While, the force sensors integrated into the sharpening module 204 use strain gauge to measure the pressure exerted during tool contact. As the whetstone 204e presses against the tool, the sensor’s internal element deforms slightly, causing a measurable change in electrical resistance. This signal is amplified and sent to the microcontroller, which uses it to assess whether the applied pressure is within safe and effective limits. If the force exceeds thresholds, the microcontroller adjusts positioning or halts sharpening to prevent tool/equipment damage or over-grinding.

[0045] In case, the frame 107 along with the sensors identifies that the tool/equipment requires mechanical adjustment such as loose, misaligned, or corroded screws, then the microcontroller actuates a maintenance module 205 mounted on the platform 111 to perform automated condition-based screwing operations. The maintenance module 205 includes a grip-and-twist arrangement 205a operably connected to a mechanical linkage 205b, configured to grip and rotate screws for tightening and loosening.

[0046] The grip-and-twist arrangement 205a consists of a pair of opposing servo-actuated jaws that securely grip the screw head, and a central rotating shaft connected to a stepper motor. Once the jaws clamp onto the screw, the motor rotates the shaft to perform tightening or loosening. A built-in torque sensor monitors the applied force, ensuring accurate screwing without damaging the threads. The microcontroller dynamically adjusts grip pressure and rotation speed based on screw type and torque readings for optimal performance.

[0047] The grip-and-twist arrangement 205a is mounted on a mechanical linkage 205b comprising interconnected arms and pivots that allow vertical and horizontal movement of the entire unit. This linkage 205b is actuated by micro stepper motors and guided by linear bearings for smooth, precise motion. Positional encoders track the linkage 205b movement, ensuring the tool aligns accurately with each screw location. The microcontroller governs linkage 205b motion in coordination with the grip-and-twist arrangement 205a, enabling adaptive positioning to reach various screw types or locations during maintenance operations.

[0048] Furthermore, a torque sensor integrated with the grip-and-twist arrangement 205a to monitor and control the applied torque during screwing operation. The torque sensor comprises a strain gauge configured to detect torsional deformation as the shaft of the arrangement 205a rotates, generating corresponding electrical signals that are amplified and transmitted to the microcontroller, which dynamically adjusts the rotational force applied by the motor based on real-time torque feedback, thereby preventing over-tightening or thread damage and ensuring optimal screw engagement for each specific tool/equipment.

[0049] Further, a high-resolution camera 205c positioned to visually assess the condition and alignment of screws, enabling adaptive control based on visual and torque feedback. The high-resolution camera 205c operates using a CMOS sensor array that captures detailed visual data of the screw and surrounding tool surface. Integrated with an adjustable lens and autofocus means, it provides sharp, real-time imaging under variable lighting conditions. An LED illumination ring ensures consistent visibility, even in low-light zones. The captured images are transmitted to the microcontroller, where image recognition protocols analyse screw condition, alignment, and fit. This visual feedback enables adaptive screwing operations by correcting misalignments or identifying worn or mismatched screws.

[0050] When the tools or equipment’s handle passed through the frame 107 and input sensors detects imperfections such as splinters, uneven texture, or wear, then the microcontroller actuates a handle sanding module 206 mounted on the platform 111 for precise and uninform sanding of handle of tool/equipment. The handle sanding module 206 includes a vertical rod 206a securely mounted on the maintenance platform 111. A motorized sliding unit 206b attached to the vertical rod 206a enabling precise vertical movement of the sanding tool along the handle’s length.

[0051] The motorized sliding unit 206b consists of a carriage driven by a lead screw coupled with a stepper motor. When activated by the microcontroller, the motor rotates the lead screw, causing the carriage to move vertically along the rod 206a. Linear bearings ensure smooth, guided motion with minimal friction. Integrated position sensors provide real-time feedback on the carriage’s location, enabling precise vertical control on a C-shaped member 206c connected to the sliding unit 206b via a third motorized ball-and-socket joint 206d allowing multi-directional adjustment to conform to the handle’s contours and varying sanding angles.

[0052] The C-shaped sanding member 206c is a curved frame designed to partially enclose the tool handle, ensuring consistent contact during sanding. The inner surface of the C-shaped frame holds an abrasive sheet 206e secured by adhesive. Micro-servo motors embedded within the joint 206d enable dynamic angular positioning, while feedback from force and surface sensors ensures optimal sanding pressure and contour alignment during operation. The third motorized ball-and-socket joint 206d allow multi-directional adjustment to the member 206c and works internally in the similar manner as the second motorized ball-and-socket joint 204f operates.

[0053] The abrasive sheet 206e mounted along the inner surface of the C-shaped member 206c for efficient sanding and smoothing of the handle. The abrasive sheet 206e is made from a flexible cloth or polyester backing coated with abrasive grains such as aluminium oxide or silicon carbide, bonded using resin adhesives. Internally, it functions by applying consistent friction to the tool handle surface, efficiently removing splinters and imperfections. Its flexibility allows it to conform to curved surfaces while maintaining uniform abrasion.

[0054] Further, a plurality of sensors comprising a position sensor, pressure sensor, and optical surface roughness sensors included in the handle sanding module 206 to detect unevenness or splinters on the handle and to activate the sanding process only when such surface imperfections are detected. The position sensor, typically a potentiometric sensor, tracks the vertical movement of the sanding module 206 along the handle. It detects the exact location of the sliding carriage on the vertical rod 206a by measuring displacement through changes in voltage. This data is sent to the microcontroller to ensure that sanding occurs only within the designated handle region and not over undesired areas, helping coordinate motion with pressure and surface roughness sensors for precise sanding.

[0055] The pressure sensor uses piezoresistive to detect the force applied by the abrasive sheet 206e onto the handle. As pressure increases during contact, the sensor element deforms or changes capacitance, generating a corresponding electrical signal. This signal is monitored in real time to ensure optimal sanding pressure. If excessive force is detected, the microcontroller adjusts the sanding unit’s position to avoid handle damage, working in tandem with the position sensor to modulate force across the handle’s full length.

[0056] The optical surface roughness sensor operates using a focused laser and a photodiode receiver to scan the handle’s surface. As light reflects off the handle, irregularities such as splinters or uneven textures scatter the light, creating measurable deviations in intensity or angle. These variations are translated into surface roughness data, which the microcontroller analyses to determine whether sanding is necessary. When roughness exceeds predefined thresholds, then only the microcontroller triggers activation of the sanding module 206, linking with pressure and position sensors for targeted, efficient smoothing.

[0057] After the tool/equipment complete the maintenance cycle, the microcontroller actuates a storage and lubrication module 112 integrated to the platform 111 for organized storage and automated lubricant dispensing for tool/equipment maintenance. The storage and lubrication module 112 includes a storage vessel 112a divided into multiple compartments for securely storing lubricants and essential maintenance tool/equipment.

[0058] A suction hose 112b connected to the lubricant section, and a dispensing nozzle 112c affixed to the hose 112b tip for controlled application of lubricant onto the tool/equipment. The suction hose 112b comprises flexible tubing connected to a vacuum-assisted pump that draws lubricant from a reservoir. When activated by the microcontroller, the suction hose 112b channels the fluid toward the dispensing nozzle 112c for controlled application.

[0059] The dispensing nozzle 112c consists of a tapered outlet connected to the suction hose 112b, equipped with a solenoid-controlled valve that regulates lubricant flow. When the microcontroller receives a signal to dispense, the solenoid opens the valve, allowing lubricant to exit in a controlled stream. The nozzle's narrow geometry ensures precise application, minimizing spillage and ensuring even coverage on the tool/equipment surface.

[0060] A proximity sensor positioned near the nozzle 112c to verify proper alignment with the target tool/equipment before dispensing and preventing spillage or wastage. The proximity sensor generates an electromagnetic field near the dispensing nozzle 112c. When a tool enters this field, it causes a measurable change in capacitance or inductance. This change is converted into an electrical signal sent to the microcontroller, confirming proper alignment before lubricant is dispensed to prevent spillage.

[0061] Additionally, a microphone 113 is integrated into the housing 101 to enable hands-free access to tools and equipment during various tasks. The microcontroller upon receiving the user’s commands activates the gripping unit on the plate 201, thereby streamlining tool access and enhancing user convenience. The microphone 113 operates using a MEMS (Micro-Electro-Mechanical Systems) element. It detects sound waves, causing a diaphragm to vibrate, which alters the capacitance between internal plates. This variation is converted into an electrical signal, amplified, and sent to the microcontroller, which processes voice commands to activate specific modules, enabling hands-free operation.

[0062] A holographic projection unit 114 is configured with the housing 101 to project interactive visual guidance and tool/equipment condition status. The projection is dynamically updated based on real-time data inputs from the microcontroller. The holographic projection unit 114 uses a laser-based light source and spatial light modulators (SLMs) to generate 3D images in mid-air above a designated display area. Interference patterns are digitally encoded and projected through diffraction optics to reconstruct the hologram. The microcontroller continuously updates the projection based on real-time sensor data, displaying tool conditions, module status, and interactive guidance visuals.

[0063] Furthermore, the housing 101 includes multiple designated compartments 115 for storing tool/equipment used in maintenance and repair. Each compartment integrated with a counting proximity sensor to detect and track the number of items stored in each compartment and an alert is transmitted via a computing unit when the detected item count exceeds or falls below predefined thresholds. The counting proximity sensor operates using ultrasonic technology to detect the presence of tools within each compartment. It emits pulses and measures the reflected signal to determine object count and spacing. Each time a tool is added or removed, the sensor registers the change and updates the internal inventory data accordingly.

[0064] When the sensor data indicates that tool count exceeds or falls below set thresholds, the microcontroller sends a digital alert signal to the computing unit via a wireless interface. The computing unit, equipped with embedded protocols and processors which processes this data and generates notifications or visual alerts on a connected display or user interface for instance on a mobile phone, or tablet etc.

[0065] The present invention works best in the following manner, where the housing 101 as disclosed in the invention is supported on plurality of extendable legs 102 terminating in the motorized omnidirectional wheels 103, enabling stable positioning and autonomous mobility across the workspace. The inlet 104 arranged on the housing 101, integrated with the motorized sliding gate 105, facilitates opening of housing 101 for secure placement and retrieval of the tool or equipment. The conveyor belt 106 disposed within the housing 101, actuated by the microcontroller to transport the tool/equipment beneath the U-shaped sensor-integrated frame 107, which performs assessment of tool condition using the optical sensor, IR sensor, and edge detection sensor. Upon detection of wear or damage, the microcontroller actuates the two-axis motorized guiding rail 108 that repositions the pneumatic linkage 109 terminating in the first ball-and-socket gripping unit 110 to pick and relocate the tool or equipment. The tool is placed on the motorized plate 201 positioned on the maintenance platform 111, which rotates to align the tool as per maintenance requirements.

[0066] In continuation, based on the sensor analysis from the frame 107, if blade dullness or edge deformation is detected, the microcontroller actuates the sharpening module 204 to perform corrective sharpening; if loose or misaligned screws are identified, the microcontroller actuates the maintenance module 205 to carry out torque-controlled screwing operations by grip-and-twist arrangement 205a; and if splinters or roughness are present on the tool handle, the microcontroller actuates the handle sanding module 206 for surface correction. After the maintenance operation, the tool is repositioned by the gripping unit 110 to the storage and lubrication module 112, where the dispensing nozzle 112c applies lubricant, confirmed by proximity sensor feedback. The tool is then stored in designated compartments 115 within the housing 101, each integrated with counting proximity sensors that detect and update tool inventory. If the count exceeds or falls below predefined thresholds, an alert is generated by the computing unit and transmitted to the user interface. The microphone 113 integrated on the housing 101 allows the user to issue voice commands, and the holographic projection unit 114 displays real-time visual guidance, operational feedback, and tool condition data for seamless user interaction.
