[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to a guest assisting device that automatically assists guests, reduces manual labor, and ensures a pleasant, healthy environment by detecting odour and dust levels to maintain high indoor air quality.

[0023] Referring to Figure 1, a guest assisting device is illustrated, comprises of a frame 101 constructed with four telescopic rods 102 having a plurality of trays 103, a plurality of wheels 104 connected underneath the frame 101 by means of articulated rocker-bogie arrangement 105, a holographic projection unit 106 mounted on the frame 101, a plurality of circular plates 107 arranged over one of the trays 103, each configured with an expansion pulley 108, a scissor arrangement 109 mounted over a slider 110 installed on the tray, a conveyor belt 111 provided on the tray, an artificial intelligence based camera 112 mounted with the frame 101, an L-shaped articulated telescopic link 113 is mounted on the frame 101 having a plate 114, a compartment 115 is formed on one of the trays 103, a plurality of UV (ultraviolet) emitters 116 are installed in the compartment 115, a plurality of articulated L-shaped telescopic arms 117 each having a cup 118 at an end, a robotic limb 119 attached with the tray, a vacuum unit 120 attached within the frame 101 and a touch enabled display panel 121 is mounted on the frame 101.

[0024] The device discloses herein includes a frame 101, constructed with four telescopic rods 102, serves as the primary structural support for the entire assembly, providing a flexible yet stable foundation. Between these rods 102, a plurality of trays 103 is arranged in a stacked manner, effectively utilizing the vertical space provided by the adjustable frame 101. The telescopic rods 102 are powered by a pneumatic unit that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the rods 102. The pneumatic unit is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the rods 102 and due to applied pressure the rods 102 extends and similarly, the microcontroller retracts the rod by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the rods 102 for positioning the trays 103.

[0025] The trays 103 are designed to hold or store various materials, items, or components, providing a clear organization. The stacked arrangement maximizes space efficiency, enabling easy access to items stored on each tray. The trays 103 made of materials like plastic, metal, or wood, ensuring durability and stability.

[0026] For enabling climbing of stairs, a plurality of wheels 104 are connected underneath the frame 101 by means of articulated rocker-bogie arrangement 105. The rocker bogie arrangement comprises a first angular fixture connected with the frame 101 by means of a first pivot joint, and a second angular fixture coupled with the first angular fixture via a second pivot joint, with the ends of the first and the second angular fixtures provided with the motorized wheels 104. The first pivot joint connects the rocker to the vehicle's frame 101, allowing the rocker to pivot vertically in response to changes in height. The second pivot joint connects the bogie to the rocker, allowing the bogie to move independently of the rocker while still remaining attached to it. This articulation enables the wheels 104 at the end of the bogie to maintain contact with the ground, regardless of the obstacles encountered. As the vehicle moves over uneven terrain, one of the wheels 104 rise or fall due to the relative motion of the rocker and bogie, but the arrangement ensures that at least one wheel on the bogie remains in contact with the ground at all times, providing continuous traction. The motorized wheels 104 at the end of the bogie are driven by motors to propel the vehicle forward, while the pivot joints and angular fixtures absorb the shocks from rough terrain, preventing the vehicle from tipping over. This dynamic interaction between the joints, fixtures, and wheels 104 allows the vehicle to navigate complex, rocky, or sloped environments with greater stability and mobility.

[0027] A user interface is adapted to be installed with a computing unit of a guest to enable wireless communication with a communication unit connected with a microcontroller provided with the frame 101 to summon the frame 101 as per requirement for delivery of goods and the microcontroller accordingly actuates the wheels 104 to translate the frame 101 to the guest for delivering goods. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet. The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0028] To project images to guide staff with positioning goods on the trays 103 for a safe and efficient delivery while delivering goods to multiple guests, a holographic projection unit 106 is mounted on the frame 101. The holographic projection unit 106, works by emitting focused light to project images that guide staff in positioning goods on the trays 103 for safe and efficient delivery. When activated by the microcontroller, it powers the light source, typically an LED or laser. The light is directed through lenses or mirrors to focus the beam, creating an accurate image or pattern that assists staff in correctly positioning the goods while delivering to multiple guests.

[0029] A plurality of circular plates 107 is arranged over one of the trays 103, each configured with an expansion pulley 108 for accommodating food dishes of various dimensions and each of the plates 107 is arranged over the tray by means of a scissor arrangement 109 mounted over a slider 110 installed on the tray to enable a positioning of the food dish onto a conveyor belt 111 provided on the tray to convey the food dish towards a storing surface. These plates 107 are designed to hold food dishes of varying sizes, and each plate features the expansion pulley 108. The expansion pulley 108 allows the plates 107 to adjust in size and securely hold dishes of different dimensions.

[0030] The scissor arrangement 109 is a mechanical arrangement that typically consists of two or more pivoted arms 117 that move in a scissor-like motion. In this case, the scissor arrangement 109 is mounted on the slider 110, which is installed on the tray. The slider 110 allows the scissor arrangement 109 to move laterally, providing the ability to position the circular plates 107 at different points across the tray. The scissor arrangement 109 ensures that the plates 107 can be adjusted to accommodate the varying sizes of the food dishes, lifting or lowering the plates 107 as needed.

[0031] Once the food dish is properly placed on the plate, the scissor arrangement 109 aids in moving the dish onto the conveyor belt 111. The conveyor belt 111 operates in a continuous loop, allowing dishes to move smoothly from the tray to the storing surface. The conveyor is likely motorized, enabling it to transport the dishes at a consistent speed and directing them to the storing area.

[0032] The scissor arrangement 109 adjusts the height or positioning of the circular plates 107, enabling them to align with the food dishes. Once aligned, the plate moves the dish onto the conveyor belt 111. The slider 110 arrangement helps ensure that the movement of the plates 107 is smooth and precise

[0033] A plurality of articulated L-shaped telescopic arms 117, each having a cup 118 at an end for covering the dishes to keep the food secure during delivery. The telescopic arm extends and retracts by using nested sections that
slide within each other, driven by pneumatic unit. The pneumatic unit is for extension and retraction operates using compressed air to drive a piston inside a cylinder. When air is supplied to one side of the piston, it creates pressure that pushes the piston arm outward, causing extension. To retract, air is supplied to the opposite side while the initial chamber is vented, pulling the piston arm back.

[0034] The cup 118 comprises a rigid outer shell made from materials like food-grade plastic or lightweight metal (such as aluminum), which offers durability and protection against external elements. The interior surface of the cup 118 is often smooth and designed to cradle the dish or container in a way that prevents it from tipping over or shifting during movement. To further enhance security, the cup 118 may have internal cushioning or a soft, rubberized lining to absorb any impacts and prevent the food from being damaged. Also, robotic limb 119 attached with the tray for adjusting position of the dishes on the storage surface.

[0035] For maintaining a temperature of the covered food within a predetermined temperature range during deliver, a peltier unit is installed with each of the cup 118. The peltier unit consists of two types of semiconductors, n-type (negative) and p-type (positive), which are connected in a series. When a DC electric current passes through these junctions, one side absorbs heat and cools down (the cooling side), while the other side releases heat and w arms 117 up (the heating side). This effect creates a temperature difference, allowing one side to cool and the other to heat up. The cool side can be used to maintain the temperature of the covered food, while the hot side requires heat dissipation, often managed using heat sinks or fans to prevent overheating.

[0036] Additionally, an artificial intelligence based camera 112 is mounted with the frame 101, records delivery of the goods to the user wherein the communication unit relays the recorded footage to a computing unit of a staff to verify completed delivery of goods. The artificial intelligence based imaging unit is constructed with a camera 112 lens and a processor, wherein the camera 112 lens is
adapted to capture a series of images of the surrounding present in proximity
to the frame 101. The processor carries out a sequence of image processing
operations including pre-processing, feature extraction, and classification by
utilizing artificial intelligence and machine learning protocols. The image
captured by the imaging unit is real-time images of the frame 101 surrounding.

[0037] The artificial intelligence based imaging unit is in communication with a
microcontroller, wherein the microcontroller used herein is an Arduino Uno
microcontroller. The artificial intelligence based imaging unit transmits the
captured image signal in the form of digital bits to the microcontroller. The
microcontroller upon receiving the image signals compares the received image
signal with the pre-fed data stored in a database and constantly.

[0038] Furthermore, an L-shaped articulated telescopic link 113 is mounted on the frame 101 and having a plate 114 at end for knocking door and pressing doorbell of guests while delivering goods. The telescopic link 113 extends and retracts by using nested sections that slide within each other, driven by pneumatic unit. The pneumatic unit is for extension and retraction operates using compressed air to drive a piston inside a cylinder. When air is supplied to one side of the piston, it creates pressure that pushes the piston rod outward, causing extension. To retract, air is supplied to the opposite side while the initial chamber is vented, pulling the piston link 113 back.

[0039] Typically, the plate 114 is made from durable materials like metal or high-strength plastic. The plate 114 is ergonomically shaped to fit comfortably against a door surface, ensuring that the knocking action is both effective and efficient. It is often positioned at an optimal angle to mimic a human hand’s knocking motion or to apply consistent pressure on a doorbell button.

[0040] A compartment 115 is formed on one of the trays 103 for storing of fabrics and a plurality of UV (ultraviolet) emitters 116 are installed in the compartment 115 for disinfecting the fabrics. The UV (ultraviolet) emitters 116, typically UV-C light sources, are used to disinfect the fabrics by emitting radiation that disrupts the DNA or RNA of microorganisms like bacteria, viruses, and fungi. UV-C light is highly effective in killing or inactivating pathogens by preventing their replication. The UV radiation penetrates the cells of the microorganisms, causing irreversible damage to their genetic material, rendering them unable to function or reproduce. The effectiveness of this process depends on factors like the intensity of the UV light, the duration of exposure, and the distance between the emitters 116 and the fabric.

[0041] Additionally, an odour sensor embedded with the frame 101 detects an odour level in the room. The sensor works by detecting the presence of specific chemicals or gases in the air that are typically associated with odors. These sensors typically operate through a process of chemical interaction or physical absorption of odor-causing molecules, which leads to a measurable change in the sensor’s properties. The sensor contains a sensing element, often made from materials like metal oxide semiconductors (MOS) or conductive polymers, which react to the target gas or molecules in the air. When an odor molecule, such as ammonia, hydrogen sulfide, or other compounds associated with poor hygiene, comes into contact with the sensing material, it causes a chemical reaction that changes the material's electrical conductivity or resistance. This change is then detected by the sensor’s circuitry and converted into a signal, which is processed to determine the concentration of the odor. If the detected odor level exceeds a preset threshold, the sensor activates a communication unit to alert staff, signaling the need for hygiene improvement.

[0042] For detecting a dust level in the room, a dust sensor is embedded with the frame 101. The dust sensor uses a photodiode, an LED light source, and a light detector. The sensor emits a light beam (usually infrared) into the air within the room. When dust particles are present in the air, they scatter or reflect the light in various directions. The photodiode or light detector then measures the amount of light that is scattered back from the particles. The more dust particles present, the greater the amount of light scattering occurs. This scattered light is detected by the sensor, and the sensor's microcontroller processes the data to determine the dust concentration level.

[0043] Upon detecting dust level in the room, a vacuum unit 120 attached within the frame 101 to suction the detected dust. The vacuum unit 120 works through a motor-driven fan that generates a pressure differential within the vacuum unit 120. When the unit is turned on, the motor powers the fan, creating a low-pressure area inside the vacuum, which draws in air and any particles, such as dust, that are present in the room. The air and dust enter through an intake nozzle or hose and are funneled into a filtration unit. The dust and debris are trapped in the filtration medium, which can be a dust bag, filter, or cyclone separator, while the filtered air is expelled back into the room.

[0044] In the context of detecting dust levels, sensors measure the concentration of dust particles in the air, typically using optical or laser-based technology that detects light scattering by airborne particles. When the concentration of dust particles exceeds a predefined threshold level, the sensor triggers the activation of the vacuum unit 120. This threshold is determined based on the specific concentration level of dust particles in the air, ensuring the vacuum unit is activated only when necessary. The vacuum's suction force is then directed towards the areas with the highest dust concentration, effectively removing particles from the air or surfaces to maintain cleanliness

[0045] To enable the guests to make payments by scanning codes displayed over the display, a touch enabled display panel 121 is mounted on the frame 101. The touch interactive display panel 121 as mentioned herein is typically an (Liquid Crystal Display) screen that presents output in a visible form.

[0046] The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding payments by scanning codes. The touch controller is typically connected to an inbuilt microcontroller linked with the panel through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). The microcontroller processes user commands and actuates the required components for scanning codes to make payments.

[0047] The present invention works best in the following manner, where the frame 101 is constructed from four telescopic rods 102, powered by a pneumatic unit comprising air compressor, air cylinder, air valves, and piston to extend and retract the rods 102, adjusting the position of stacked trays 103. These trays 103, are made of durable materials like plastic, metal, or wood, store and organize goods efficiently. A rocker-bogie arrangement 105 with motorized wheels 104 enables the device to climb stairs and navigate uneven terrain. The device is controlled wirelessly via a user interface connected to a communication unit, which utilizes a Wi-Fi module for secure connectivity. A holographic projection unit 106 guides staff in positioning goods on trays 103 during delivery. Circular plates 107 on the trays 103 adjusts to varying food dish sizes using expansion pulley 108, with a scissor mechanism moving the plates 107 onto a conveyor belt 111. Articulated telescopic arms 117 are equipped with cup 118 cover the dishes during delivery, while Peltier units maintain the temperature of the food. The device includes an AI-based camera 112 for delivery verification, while a telescopic link 113 with a plate 114 knocks doors and presses doorbells. UV emitters 116 disinfect fabrics stored on one tray, and odor and dust sensors activate a vacuum unit 120 for maintaining room hygiene. The display panel 121 allows guests to scan codes for payment, completing the process seamlessly.

[0048] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is preferably a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to functionproperly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0049] The present invention works best in the following manner, where the frame 101 is constructed using four telescopic rods 102 powered by the pneumatic unit containing the air compressor, air cylinder, air valves, and piston for vertical adjustment of stacked trays 103 made from plastic, metal, or wood for efficient storage and organization. The rocker-bogie arrangement 105 with motorized wheels 104 allows navigation over uneven terrain and stair climbing. The user interface communicates with the communication unit using the Wi-Fi module for wireless operation. The holographic projection unit 106 projects visual guides to assist in placing goods on trays 103. The circular plates 107 with expansion pulley 108 accommodate dishes of various sizes, which is supported by the scissor arrangement 109 and slider 110 for positioning over the motorized conveyor belt 111. The articulated telescopic arms 117 with cup 118 are made of food-grade material cover the dishes during transport, and each cup 118 includes the Peltier unit to maintain optimal food temperature. The AI-based camera 112 records delivery and transmits footage to staff for verification. The L-shaped articulated telescopic link 113 with the plate 114 is designed for knocking doors and pressing doorbells. The UV emitters 116 disinfect fabrics stored in the compartment 115 on trays 103. The odor sensor and dust sensor monitor hygiene levels, is activating the vacuum unit 120 to clean when thresholds are exceeded. The touch-enabled display panel 121 supports guest payments by scanning displayed codes.
