It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0019] 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.

[0020] 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.

[0021] The present invention relates to a wooden sheet segmentation assistive device that is capable of carrying out the cutting of a wooden pieces in order to attain the user-specifies shape as well as capable of determining the hardness of the wooden workpiece and accordingly applies the effort on the device for appropriate cutting.

[0022] Referring to Figure 1, an isometric view of a wooden sheet segmentation assistive device is illustrated, comprising a body 1, plurality of suction cups 2 are arranged underneath the body 1, a microphone 3 integrated in the body 1, a motorized flap 4 arranged on front portion of the body 1, plurality of robotic arms 5 arranged on inner periphery of the body 1, a touch interactive display panel 6 integrated on the body 1, an artificial intelligence-based imaging unit 7 installed in the body 1, a two-axis motorized sliding unit 8 is arranged on ceiling portion of the body 1, a hydraulic actuator 9 arranged vertically on the sliding unit 8, and a motorized cutter 10 integrated with the actuator 9.

[0023] The proposed device comprises of a body 1 which is positioned on a fixed surface. The body 1 is developed a protective exterior of the device and the components associated with the device are mounted in and over the body 1. The body 1 is preferably cuboidal in shape and made up of stainless steel that offers a corrosion resistant, strength and durability to the device and is easy to maintain. Under the body 1, plurality of suction cups 2 are arranged to adhere to the surface for securing the body 1 on the surface.

[0024] The suction cups 2 are types of tools which uses the atmospheric pressure to vacuum and hold the body 1 at one place on the surface. The suction cups 2 are consist of a circular disc which are made of a flexible material mostly rubber with a rounded edge, whenever the pressure is applied by a user in the center of the disc, a concave shape is generated and when the cups 2 are forced against the surface, a vacuum is created in the cups 2 which causes the cups 2 to stick strongly with the surface for mounting the body 1 on the surface.

[0025] Initially the user is required to access a microphone 3 integrated in the body 1 to provide input voice commands for activating/deactivating the device. The microphone 3 works by converting sound waves into electrical signals. The microphone 3 is designed to detect variations in air pressure caused by user's voice in the surrounding and transform those pressure fluctuations into electrical signals that is further processed, stored, or transmitted to the microcontroller. Whenever, the user speaker, it creates a series of compressions and rarefactions in the surrounding medium, which constitute sound waves. The microphone 3 typically consists of a diaphragm, a magnet, and a coil.

[0026] The diaphragm is a thin, flexible membrane that vibrates in response to the changes in air pressure caused by sound waves in the housing. When the diaphragm vibrates, it moves the coil relative to the magnet, inducing an electric current in the coil due to electromagnetic induction. As the coil moves within the magnetic field of the sensor, it generates a varying electrical voltage proportional to the diaphragm's motion. This voltage represents the electrical analog of the sound waves and is often referred to as the audio signal. The electrical signal is amplified and converted into an analog electrical signal which is processed by the microcontroller. After processing the microcontroller fetches the user's voice input.

[0027] After receiving the command, the microcontroller directs a motorized flap 4 arranged on front portion of the body 1 to get opened/closed by means of a hinge joint for enabling the user to accommodate a wooden sheet on a plate arranged in the body 1. As soon as the body 1 gets opened, then the microcontroller actuates plurality of robotic arms 5 arranged on inner periphery of the body 1 to grip ends of the sheet for properly securing the sheet in the body 1.

[0028] The robotic arms 5 contain robotic link and an end effector which is installed at free end of the link. The robotic link is made of several segments that are attached together by joints also referred to as axes. Each joint of the segments contains a step motor that rotates and allows the robotic link to complete a specific motion in translating the equipped effector towards the sheet. Further, the step motor, is a kind of motor which rotates in small, precise steps, unlike other motors which rotates continuously.

[0029] The step motor comprises of a rotor and stator. The rotor is the rotating part of the motor, and the stator is the stationary part. The stator consist of multiple conducting coils of wire which are arranged in a specific manner. When current flows through the coils, the magnetic field is setup around the coil and that cause the rotor to move in precise steps to translate the link towards the sheet for positioning the end effector in contact with sheet. Further the end effector comprises of a pair of jaws assembled with each other by means of another step motors which enables the opening/closing of the jaws in order to grip sheet and after gripping the microcontroller directs the arms 5 again for positioning the gripped sheet properly.

[0030] Now a user is required to access a touch interactive display panel 6 integrated on the body 1 to provide input specifications regarding a user-desired segment of the sheet. The touch interactive display panel 6 mapped herein consists of multiple tiny electrically active wires. When user touch the mapping illustrated over the panel 6, the wires are pressed together and circuit is completed. Which results in flow of voltages across the circuit. That voltage flow is detected by the microcontroller linked with the panel 6 in form of electric signals. Further the signals are processed by the microcontroller to determine the user's input regarding user-desired segment of the sheet.

[0031] After receiving the input, the microcontroller actuates an artificial intelligence-based imaging unit 7 installed in the body 1 determines dimensions of the sheet. The imaging unit 7 comprises of a processor and a camera which on actuation capture the multiple image of the body 1. The camera is comprised of a lens and a digital camera sensor, wherein the camera lens takes all the light rays rebounding around the body 1 and utilizes the lenses to transmit them to a single point for creating a sharp image. When all of those light rays rebound back and meet together on a digital camera sensor, create a digital image of the body 1 by performing various operations like pre-processing, feature extraction and classification which is transmitted to the processor.

[0032] The processor further extracts all the required information from the digital images and transmit to microcontroller, which further processes the information shared by the processor in order to determine dimensions of the sheet and based on which the microcontroller evaluates particular portions on the sheet that are to be cut. Post evaluation, the microcontroller directs a two-axis motorized sliding unit 8 is arranged on ceiling portion of the body 1 to provide two-axis translation to a hydraulic actuator 9 arranged vertically on the sliding unit 8.

[0033] The two-axis sliding unit 8 are designed to control both horizontal (side-to-side) and vertical (up-and-down) movement of actuator 9. The motorized two-axis sliders use electric motors and precise gear mechanisms to control the movement of the actuator 9. The two-axis slider comprises of a pair of sliding rail assembled perpendicular to each other and on actuation the gear mechanism translates the block in two direction for positioning the actuator 9 over the evaluated portion.

[0034] A motorized cutter 10 integrated with the actuator 9. In simultaneous to actuation of the sliding unit 8, the microcontroller directs the hydraulic actuator 9 to extend/retract for positioning the cutter 10 on the evaluated portion. The extension of the actuator 9 is powered by a hydraulic unit associated with the device and includes a hydraulic pump, solenoid valve and hydraulic piston-cylinder. The hydraulic pump used herein extract the hydraulic oil from a reservoir and pressurized the fluid mechanically.

[0035] The hydraulic pump is consist of two main parts including a motor and a propeller. The motor rotates the propeller which uses the energy from the motor drive to draw in hydraulic oil from the reservoir and compress to elevated pressure. The compressed hydraulic oil is then sent through a discharge tube into the cylinder across the solenoid valve. As per the signal from the microcontroller, the solenoid valve opens and allows the entering of the pressurized oil in the cylinder.

[0036] The solenoid valve comprise of a gate and a magnetic coil, which on energizing generates the magnetic force which tries to push the gate to open and allow the flow of oil in the jack The pressurized oil within the cylinder tend to pushes out the piston out from the cylinder which results in extension hydraulic actuator 9s for positioning the cutter 10 on the evaluated portion and followed by synchronized actuation of the cutter 10 and the sliding unit 8 to cut the sheet and move along edges of the evaluated portion, in view of attaining the user-specified segment of the sheet.

[0037] Simultaneously, a tactile sensor which is embedded on the clamps for determining hardness of the sheet. The tactile sensor employed herein is composed of an elastic body 1, ferrous probe, TMR (tunnel magneto resistive) element, and a permanent magnet. When the elastic body 1 embedded with ferrous probe touches the object under the certain size of force, deformation is produced in elastic body 1. Correspondingly, the ferrous probe is forced forward to be displaced and as a result the background magnetic field is distorted. The distorted magnetic field was detected by TMR elements and transmitted to the microcontroller in form of electrical signal. After processing the received signal, the microcontroller determine the hardness of the sheet and based on which the microcontroller regulates actuation of the cutter 10.

[0038] A battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery use a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0039] The present invention works well in the following manner where body 1 which is positioned on a fixed surface. Under the body 1, plurality of suction cups 2 are arranged to adhere to the surface for securing the body 1 on the surface. Initially the user is required to access a microphone 3 integrated in the body 1 to provide input voice commands for activating/deactivating the device. After receiving the command, the microcontroller directs a motorized flap 4 arranged on front portion of the body 1 to get opened/closed by means of a hinge joint for enabling the user to accommodate a wooden sheet on a plate arranged in the body 1. As soon as the body 1 gets opened, then the microcontroller actuates plurality of robotic arms 5 arranged on inner periphery of the body 1 to grip ends of the sheet for properly securing the sheet in the body 1. Now a user is required to access a touch interactive display panel 6 integrated on the body 1 to provide input specifications regarding a user-desired segment of the sheet. After receiving the input, the microcontroller actuates an artificial intelligence-based imaging unit 7 installed in the body 1 determines dimensions of the sheet and based on which the microcontroller evaluates particular portions on the sheet that are to be cut. Post evaluation, the microcontroller directs a two-axis motorized sliding unit 8 is arranged on ceiling portion of the body 1 to provide two-axis translation to a hydraulic actuator 9 arranged vertically on the sliding unit 8 for positioning the actuator 9 over the evaluated portion. In simultaneous to actuation of the sliding unit 8, the microcontroller directs the hydraulic actuator 9 to extend/retract for positioning the cutter 10 on the evaluated portion and followed by synchronized actuation of the cutter 10 and the sliding unit 8 to cut the sheet and move along edges of the evaluated portion, in view of attaining the user-specified segment of the sheet.
