Description:FIELD OF THE INVENTION

[0001] The present invention relates to a fruit harvesting device that is capable of assisting the user in harvesting fruits by determining the position of ripe fruits on the tree, thereby ensuring that only fruits at the optimal stage of ripeness are collected. The present invention is also capable of detecting the presence of stale spots on the fruits for preventing the plucking of stale fruits.

BACKGROUND OF THE INVENTION

[0002] The need and importance of fruit harvesting lie at the core of ensuring food quality, reducing post-harvest losses, and meeting market demands with efficiency and precision. Timely and accurate harvesting is critical to capturing fruits at their peak ripeness, which directly affects their nutritional value, taste, shelf life, and commercial appeal. As global demand for high-quality produce rises and agricultural labor becomes increasingly scarce, there is a growing need for innovative, automated harvesting solutions. These not only boost productivity and consistency but also contribute to sustainable agricultural practices by minimizing waste, preserving crop health, and enabling better resource management throughout the supply chain.

[0003] Traditional methods of fruit harvesting assistance involve manual picking using ladders, baskets, and hand tools, often guided by visual inspection. Laborers rely on experience to judge ripeness, which is inconsistent and time-consuming. These methods lack precision, are physically demanding, and result in fruit damage or loss, especially during large-scale or high-reach harvesting. Traditional fruit harvesting methods have several drawbacks, including high labor dependency, inconsistent ripeness detection, and increased risk of fruit damage. They are time-consuming, physically demanding, and inefficient for large-scale operations. Limited reach and manual handling often lead to missed or bruised fruits, reducing overall yield quality and making the process less sustainable and economically viable.

Controls in the bucket for constantly changing its position by raising and lowering, extending and retracting, and swinging the boom are foot actuated. A hopper is movably mounted on the rear section of the vehicle for selective dumping. Means carried by the bucket guide the fruit picked by a man therein into the outer end of the hollow boom, and a conduit connects the inner end of the boom to the hopper. Sub-atmospheric pressure is maintained within the hopper to generate air flow from the outer end of the boom through the boom into the hopper, whereby the picked fruit is conducted rapidly through the boom into the hopper. The front and rear sections of the vehicle are pivotally connected and variable power drive means are provided for steering one section with respect to the other section.

In addition, these existing devices also fail in detecting the presence of stale spots on the fruits for preventing the plucking of stale fruits.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of harvesting fruit by determining the position of ripe fruits on the tree and detecting the presence of stale spots on the fruit for preventing the plucking of stale fruits.

[0021] The present invention relates to a fruit harvesting device that is capable of detecting the presence of stale spots on the fruits for preventing the plucking of stale fruits. The present invention is additionally equipped to detect fruits and alert the user regarding the presence of any infected ones, ensuring timely identification of infected fruits.

[0022] Referring to Figure 1, an isometric view of a fruit harvesting device is illustrated, comprising a base 101 supported by a plurality of hydraulic actuators 102 installed at a bottom of the base 101 with motorised omnidirectional wheels 103, a sliding unit 104 installed over the base 101 with a plurality of containers 105 mounted on the sliding unit 104 by means of telescopic rods 106, an artificial intelligence-based hyperspectral imaging unit 107 installed on the base 101, a segmented cylindrical member 108 configured with an expandable pulley 109 attached with each of the container 105, a slider 110 attached with an edge of the base 101, a frame 111 with a net 112 is installed with the slider 110.

[0023] Figure 1 further illustrates a pair of articulated telescopic grippers 113 disposed on the base 101, a chamber 114 provided on the base 101, the member 108 are attached with the containers 105 by means of articulated telescopic links 115, an articulated telescopic bar 116 is mounted over the base 101 having an elongated flap 117 attached at an upper end of the bar 116 with a plurality of articulated clamps 118, an e-nose 119 installed on the container 105, a cylindrical fabric enclosure 120 is supported on the base 101 by means of a pair of telescopic poles 121 having a ring 122 at an upper end.

[0024] The device disclosed herein employs a base 101. This base 101 is typically constructed from material that include but not limited to high-strength materials such as reinforced steel or durable aluminum alloys, which provide a robust and resilient enclosure capable of withstanding physical impacts and environmental stressors. The base 101 is preferably rectangular or square in shape. The base 101 is supported by a plurality of hydraulic actuators 102 installed at a bottom of the base 101. The bottom ends of the hydraulic actuators 102 are provided with motorised omnidirectional wheels 103 for a locomotion of the base 101.

[0025] For activating the device, the user needs to press a push button which is arranged on the base 101 which in turn activates all the related components for performing the desired task. After pressing the button, a closed electrical circuit is formed and current starts to flow that powers an inbuilt microcontroller to allow all the linked components to perform their respective task upon actuation.

[0026] A sliding unit 104 is positioned over the base 101, with a plurality of containers 105 mounted on the sliding unit 104 by means of telescopic rods 106, for storing of fruits in the containers 105. An artificial intelligence-based hyperspectral imaging unit 107 is mounted on the base 101 and integrated with a processor for recording and processing images in a vicinity of the base 101. This imaging unit 107 works in synchronisation with an ethylene sensor provided on the base 101, to determine position of ripe fruits. The imaging unit 107 comprises of an image capturing arrangement including a set of lenses that captures multiple images in vicinity of the base 101, and the captured images are stored within a memory of the imaging unit 107 in form of an optical data. The imaging unit 107 also comprises of the processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller.

[0027] The ethylene sensor detects trace concentrations of ethylene, a natural plant hormone released in greater amounts by ripening fruits. Internally, the sensor typically employs a metal oxide semiconductor (MOS) sensing arrangement. In the MOS type, a thin film of metal oxide, such as tin dioxide, changes the electrical resistance when ethylene molecules interact with the surface, altering the charge distribution. This real-time ethylene level data is continuously analyzed by the imaging unit's processor, allowing to infer the proximity and ripening stage of nearby fruits. Hence, the position of ripe fruits is determined.

[0028] Upon detecting the position of the ripe fruits, the microcontroller actuates the wheels 103 to translate the base 101 towards the fruit, the hydraulic actuators 102 to raise the base 101, the sliding unit 104 to position the container 105 underneath the fruit and the rods 106 to position the container 105 near the fruit for plucking. The omnidirectional wheel 103 function by using the rotational power of a DC motor to drive the rollers of the wheel 103, which are positioned at a 45-degree angle to the central axis of the wheel 103. As the DC motor rotates the wheel 103, each roller moves independently to generate forces in multiple directions. The combination of these forces allows the wheel 103 to move the base 101 smoothly in any direction, including forward, backward, or sideways, without changing the orientation of the wheels 103. So, the wheels 103 translate the base 101 towards the fruit.

[0029] When the base 101 reaches near the fruit, the hydraulic actuators 102 raise the base 101. The hydraulic actuators 102 consist of a cylinder containing a piston, hydraulic fluid, and control valves. Upon receiving a signal from the microcontroller, a hydraulic pump is engaged, which pressurizes the fluid and directs through solenoid-controlled valves into the actuator’s cylinder. The pressurized fluid pushes against the piston, causing to extend and lift the base 101 smoothly.

[0030] Upon raising the base 101, the sliding unit 104 positions the container 105 underneath the fruit. The rods 106 then position the container 105 near the fruit for plucking. The sliding unit 104 consist of a sliding rail and a motorized slidable member connected to the sliding rail. The motorized slidable member is attached to the base 101 and sliding rail on both sides to make the container 105 slide. The slidable member is attached to a motor which provides movement to the member. The rods 106 attached with the container 105 places the container 105 near the fruit for plucking the fruit.

[0031] For gripping and plucking fruits from branches and placing into the containers 105, a segmented cylindrical member 108 with sharp edges is attached with each of the container 105. This member 108 is configured with an expandable pulley 109. The segmented cylindrical member 108 with sharp edges functions as a mechanical gripping and plucking tool, integrated with each container 105 for seamless fruit collection. This member 108 is composed of multiple curved segments arranged in a cylindrical configuration, each capable of slight radial movement. These segments are connected via joints and are actuated by the expandable pulley 109, essentially a flexible belt looped through the segments and connected to a central actuator. When the actuator engages, it adjusts the tension on the pulley 109, causing the segments to expand outward or contract inward. In the expanded state, the member 108 surrounds the fruit and aligns with the stem. As the pulley 109 contracts, the sharp edges of the segments close in, gripping the stem securely and applying a controlled force to pluck the fruit cleanly from the branch.

[0032] The members 108 are attached with the containers 105 by means of articulated telescopic links 115. The articulated telescopic links 115 operate by utilizing the pneumatic unit. The pneumatic unit 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 114 is vented, pulling the piston rod back.

[0033] A laser sensor that is embedded in the member 108 detects the dimension of the fruit in front of the member 108. The laser sensor operates based on the principle of triangulation. In triangulation-based sensors, a laser diode emits a focused beam of light toward the fruit. When the beam strikes the surface, it reflects back to a position-sensitive detector (PSD) at a known angle. The position of the reflected spot on the detector changes depending on the distance to the fruit, allowing the sensor to calculate the exact distance and contour. The collected spatial data is then processed to generate a 3D profile of the fruit in real time. Hence, the dimension of the fruit in front of the member 108 is detected. In accordance to the detected dimension of the fruit, the expandable pulley 109 expand/retract to grip and pluck the fruit.

[0034] A tactile sensor is embedded in the member 108 to detect hardness of the gripped fruit for detecting stale spots to prevent plucking of stale fruits. The tactile sensor comprises of an array of pressure-sensitive elements, such as capacitive sensors, embedded within a flexible, soft material that lines the gripping surface. When the member 108 gently closes around the fruit, these sensors register localized pressure distributions and force feedback from the fruit's surface. Variations in capacitance across the array are interpreted by the microcontroller to create a tactile map of the fruit’s firmness. Softer or unusually yielding areas indicate potential spoilage, bruising, or staleness. This data is then compared to preset thresholds for healthy fruit texture. If the tactile sensor detects irregular softness beyond the acceptable range, then the sensor signals the actuator to release the fruit without plucking.

[0035] With an edge of the base 101, a slider 110 is attached. The slider 110 works in the similar manner as the sliding unit 104 mentioned above. A frame 111 with a net 112 is connected with the slider 110 for collection of fruits falling from branches. For picking the fruits from the net 112 and storing in a chamber 114 provided on the base 101, a pair of articulated telescopic grippers 113 is disposed on the base 101. This chamber 114 receives fruits from the containers 105 for storage. The telescopic grippers 113 consist of telescopic parts composed of nested segments that extend and retract by utilizing the pneumatic unit. The pneumatic unit 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 114 is vented, pulling the piston rod back. The gripping fingers, open around the fruit and close gently to ensure a secure yet non-damaging grip. The arm then retracts telescopically, carrying the fruit toward the chamber 114.

[0036] An articulated telescopic bar 116 is mounted over the base 101 having an elongated flap 117 attached at an upper end of the bar 116. The telescopic bar 116 works in the similar manner as the telescopic links 115 by utilizing the pneumatic unit as explained above. Over the flap 117, a plurality of articulated clamps 118 is attached for supporting a branch during plucking of fruit, when the imaging unit 107 detects the branch to be sagging. The articulated clamps 118 consist of a multi-jointed mechanical structure, often driven by motors, which allow the clamp 118 to adapt the shape and grip based on the thickness and orientation of the branch. When the imaging unit 107 detects that a branch is sagging, then the microcontroller deploys the clamps 118.

[0037] For fetching a weather forecast, a weather module is linked with the microcontroller. The weather module is equipped with a micro-sensor array that includes components such as a barometric pressure sensor, temperature sensor, humidity sensor. The barometric pressure sensor measures atmospheric pressure to help predict weather changes, such as the likelihood of storms or clear skies. The sensor typically consists of a diaphragm that deforms slightly in response to changes in external air pressure. This deformation alters the resistance in an embedded sensing circuit, which is then converted into an electrical signal. The sensor outputs this signal as a digital pressure value, which the microcontroller reads and interprets. A rapid drop in pressure, for example, indicate an approaching storm, while a steady or rising pressure suggests stable weather.

[0038] The temperature sensor in the weather module usually operates based on thermistor. In thermistor-based sensors, a material’s electrical resistance changes predictably with temperature. The sensor measures this resistance and translates into a temperature value using calibration curves. The microcontroller uses this temperature input to assess environmental conditions. Humidity sensors commonly use capacitive sensing to measure the relative humidity in the air. Internally, the sensor consists of a hygroscopic dielectric material placed between two conductive plates, forming a capacitor. As ambient humidity changes, the moisture absorbed by the dielectric layer alters the dielectric constant, which in turn changes the capacitance. The sensor's internal circuitry detects this change and converts into a corresponding digital humidity value. This data allows to monitor moisture levels in the air.

[0039] The user is notified via a user interface connected by means of a communication module provided with the microcontroller, along with an optimal schedule for harvesting of fruits as per forecasted weather. The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The Wi-Fi module contains transmitters and receivers that use radio frequency signals to transmit data wirelessly to the microcontroller. The wireless module typically includes components such as antennas, amplifiers, and processors to facilitate communication and further connected to networks such as Wi-Fi, Bluetooth, or cellular networks, allowing devices to exchange information over short or long distances.

[0040] A disease detection module is configured with the imaging unit 107 which receives images of fruits from the imaging unit 107 along with data from an e-nose 119 installed on the container 105. This detects the presence of volatile compounds from the fruits to determine infected fruits. The microcontroller then actuates the communication module to push an alert to the user interface regarding collection of the infected fruit in the container 105. The disease detection module operates by first receiving high-resolution images of the fruits from the imaging unit 107, which are analyzed using image processing protocols to detect visible signs of disease, such as discoloration, lesions, or surface mold.

[0041] Simultaneously, the e-nose 119, analyzes the chemical composition of volatile organic compounds (VOCs) emitted by the collected fruits. The e-nose 119 comprises an array of gas sensors, typically metal oxide, each sensitive to specific VOCs associated with fruit decay. The data from both sources is processed using pattern recognition protocols within the module to cross-verify symptoms and identify potentially infected fruits with high accuracy. If an anomaly is detected, the disease detection module sends the signal to the microcontroller, which in turn activates the communication module. This module then pushes an alert, containing details of the suspected infection, to the user interface, notifying the operator in real time.

[0042] For containing larger fruits while maintaining aeration, a cylindrical fabric enclosure 120 is supported on the base 101 by means of a pair of telescopic poles 121 having a ring 122 at an upper end. This assists in plucking the larger fruits while providing the necessary aeration during the storage for keeping the fruit fresh. The cylindrical fabric enclosure 120 is made from the perforated fabric that allows continuous airflow, reducing moisture buildup and heat accumulation around the fruits. The enclosure 120 is supported vertically by the pair of telescopic poles 121, each consisting of nested tubular segments that extend or retract to adjust the height based on the volume of collected fruit.

[0043] At the upper end of the poles 121, the ring 122 maintains the circular opening of the enclosure 120, ensuring the fabric stays open and stable for easy fruit deposition. When the collection of larger fruits is detected, the microcontroller signals the poles 121 to extend, raising the ring 122 and expanding the enclosure’s vertical space. The structure not only accommodates bulkier produce but also promotes aeration through the material and design, protecting fruit quality during temporary storage.

[0044] A weight sensor is embedded in the container 105 for detecting weight of fruits collected to show in the user interface. The weight sensor is typically a load cell, most commonly a strain gauge type which converts the mechanical force exerted by the accumulating fruit into an electrical signal. The load cell consists of a metal structure that slightly deforms under the weight; strain gauges attached to this structure experience corresponding changes in electrical resistance. These resistance changes are converted into voltage variations through a Wheatstone bridge circuit. The analog signal is then amplified and digitized using an analog-to-digital converter (ADC) before being sent to the microcontroller. The microcontroller processes this signal to calculate the real-time weight of the fruit inside the container 105 and updates the user interface accordingly.

[0045] The present invention works best in the following manner, where the base 101 as disclosed in the invention is supported by the plurality of hydraulic actuators 102 provided with motorised omnidirectional wheels 103 for the locomotion of the base 101.

The segmented cylindrical member 108 with sharp edges, the member 108 configured with the expandable pulley 109, attached with each of the container 105 for gripping and plucking fruits from branches and placing into the containers 105. The members 108 are attached with the containers 105 by means of articulated telescopic links 115.

The slider 110 attached with the edge of the base 101 where the frame 111 with the net 112 is installed with the slider 110 for collection of fruits falling from branches.
