Description

Technical Field

[0001] This invention relates to the field of human-machine interaction technology for robotic arms, specifically to a method, system, device, and medium for interactive control of robotic arm food retrieval. Background Technology

[0002] In the field of food service automation, existing technologies for robotic arm food retrieval and interaction control typically employ a preset program control method. Specifically, the robotic arm moves to the food retrieval position according to a pre-set motion trajectory, grips the food with a fixed clamping force using its grippers, and then remains stationary, waiting for the user to retrieve the food.

[0003] Throughout the entire food retrieval process, the robotic arm's gripper release action relies entirely on user-inputted commands: when a user retrieves their food, they must send a release signal to the robotic arm by triggering a preset button, touch sensor, or voice command. Only after receiving this signal will the robotic arm control the gripper to release. This control logic, which depends on active user input, results in significant operational redundancy in the food retrieval process. Users must perform additional command input operations outside of the food retrieval action, increasing the complexity of the process and potentially causing interruptions or delayed gripper release due to input delays or operational errors, thus impacting efficiency and user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a robotic arm food retrieval interactive control method, system, device, and medium.

[0006] Preferably, the step of acquiring force in any direction based on the force sensor of the robotic arm, acquiring force changes based on the sensed force in any direction, and controlling the gripper of the robotic arm to release based on the force changes to achieve interactive control of the robotic arm picking up food includes:

[0007] Step S1: Control the robotic arm holding the skewered bamboo sticks to reach the preset position and clear the force sensing of the robotic arm.

[0008] Step S2: When the force sensing of the robotic arm changes, control the gripper of the robotic arm to loosen by a certain width;

[0009] Step S3: When the human hand is removed, control the robotic arm to return to the preset position.

[0010] Preferably, step S1 includes: obtaining the force of each mechanical joint based on the torque sensor integrated in each joint of the robotic arm; and obtaining the end-effector force by back-calculating the obtained force of each mechanical joint through a dynamic model.

[0011] Preferably, step S3 includes: setting up a detection device in a preset food collection area to detect whether a hand enters; when a hand is detected, triggering an image acquisition device; acquiring image information of the food collection area in real time through the image acquisition device; performing hand recognition based on the image information; when no hand information is detected in the image information, and the robotic arm gripper releases a certain width of preset time, it is considered that the hand has been removed, and the robotic arm is controlled to return to the preset position.

[0012] A robotic arm food-fetching interactive control system according to the present invention includes:

[0013] The change sensing module is used to obtain force in any direction based on the force sensing of the robotic arm, and to obtain the change in force based on the sensed force in any direction.

[0014] The control module is used to control the gripper of the robotic arm to release based on force changes, so as to realize the interactive control of the robotic arm to pick up food.

[0015] Preferably, the system includes:

[0016] Module M1: Controls the robotic arm holding the skewered bamboo sticks to reach the preset position and resets the force sensing of the robotic arm to zero.

[0017] Module M2: When the force sensing of the robotic arm changes, it controls the gripper of the robotic arm to loosen by a certain width;

[0018] Module M3: When the human hand is removed, the robotic arm is controlled to return to the preset position.

[0019] Preferably, the module M1 includes: obtaining the force of each mechanical joint based on the torque sensor integrated in each joint of the robotic arm; and obtaining the end force by back-calculating the obtained force of each mechanical joint through a dynamic model.

[0020] Preferably, the module M3 includes: setting a detection device in a preset food pick-up area to detect whether a hand enters; when a hand is detected, triggering an image acquisition device; acquiring image information of the food pick-up area in real time through the image acquisition device; performing hand recognition based on the image information; when no hand information is detected in the image information, and the robotic arm gripper releases a certain width of preset time, it is considered that the hand has been removed, and the robotic arm is controlled to return to the preset position.

[0021] According to an electronic device provided by the present invention, the electronic device includes a memory and at least one processor, wherein the memory stores instructions;

[0022] The at least one processor invokes the instructions in the memory to cause the electronic device to execute the various steps of the robotic arm food retrieval interaction control method as described above.

[0023] According to a computer-readable storage medium provided by the present invention, the computer-readable storage medium stores instructions, which, when executed by a processor, implement the various steps of the robotic arm food-picking interactive control method described above.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This invention achieves a safe and stable human-computer interaction process for food retrieval by employing precise force control sensing of a robotic arm and real-time width feedback of the end gripper.

[0026] 2. This invention utilizes the force sensing capability of the robotic arm, eliminating the need for users to input additional commands. The release of the gripper is triggered simply by the force change generated when a person picks up a bamboo skewer, thus eliminating the need for users to actively operate the command input device. This simplifies the food retrieval process, making food retrieval more natural and efficient for users, and reducing the inconvenience caused by redundant operations.

[0027] 3. The robotic arm integrates torque sensors in each joint, and uses a dynamic model to back-calculate the force and torque of the end effector TCP. After reaching the food retrieval position, the force is reset to zero. It can accurately sense changes in force in any direction, ensuring that the gripper releases in time when the hand comes into contact with it, avoiding squeezing or scratching the hand due to continuous gripping by the gripper, and reducing safety risks during the interaction process.

[0028] 4. Combining the detection device and image acquisition device of the preset food pick-up area, the image acquisition is triggered when a hand is detected entering. The image recognition technology monitors in real time whether the hand has been removed. At the same time, the preset time condition after the gripper releases a certain width ensures the accuracy of the hand removal judgment. This avoids the problem of the robotic arm removing too early or too late due to relying solely on a fixed time delay. It not only prevents interference with the user's food pick-up, but also improves the working efficiency of the robotic arm. Attached Figure Description
