Description

Technical Field

[0001] The invention relates to the field of skin perception, and in particular to a skin perception system for a mechanical movable component. Background Art

[0002] Active components refer to various components in moving devices such as robots and mechanical arms. Each independent moving unit in the machine is called a component. Flexible electronic skin is generally covered on the robot's mechanical arm, which allows the robot to "feel" and flexibly avoid various obstacles encountered in its progress. Flexible electronic skin contains hundreds of independent sensors. With the help of information collected by the sensors, the robot can use the so-called "sense of touch" to control its direction, identify the surrounding situation, and find the best route. Covering electronic skin in mechanical active components can improve their efficiency. In existing electronic skins, when mechanical active components are covered with electronic skin and move, when encountering obstacles, the electronic skin cannot perceive and process them in time, causing the mechanical active components to collide with the obstacles, thereby causing damage to the electronic skin and the mechanical active components. Summary of the invention

[0013] Furthermore, data is transmitted between the perception control unit, the data processing unit and the perception unit via an interface, thereby enabling the perception control unit, the data processing unit and the perception unit to perform data transmission processing, further improving the perception effect of the mechanical movable component.

[0014] Furthermore, the flexible substrate is a flexible circuit board made of a polyamide film material, thereby improving the softness of the flexible substrate.

[0019] Furthermore, the perception control unit, the data processing unit and the perception unit are communicatively connected via a CAN bus interface, thereby enabling communication transmission processing, further improving utilization efficiency.

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By setting a composite structure of a sensing unit, a data processing unit and a sensing control unit to replace the original single structure, the mechanical active component covered with the electronic skin can accurately capture obstacles when encountering obstacles in the surrounding area during the movement, so that the electronic skin can sense and process the obstacles. After the electronic skin completes the sensing, the data processing unit processes the distance of the obstacle, and when the appropriate distance is reached, the data processing unit can transmit the data to the sensing control unit to control and process the mechanical active component. When the mechanical active component does not collide with the obstacle, the electronic skin can control the mechanical active component to stop moving in time to avoid the collision between the mechanical active component and the obstacle, thereby causing damage to the mechanical active component and the electronic skin, further improving the electronic skin's ability to sense obstacles, increasing the safety performance of the mechanical active component during the movement, greatly improving the application ability of the electronic skin, making the electronic skin more widely used, and avoiding the mechanical active component from failing to sense obstacles in time during the movement;

[0023] 2. Through the sensing unit, the distance between the mechanical active component covering the electronic skin and the obstacle is sensed and processed through the infrared sensor module and the pressure sensor module, so that the distance of the obstacle can be sensed in time. The distance between obstacles is accurately controlled through the infrared sensor module, which further improves the working efficiency of obstacle sensing. The pressure sensor module can sense the moment when the mechanical active component covering the electronic skin contacts the obstacle in time, thereby avoiding the collision between the mechanical active component covering the electronic skin and the obstacle. The main control module can control the infrared sensor module and the pressure sensor module, control the use of the infrared sensor module and the pressure sensor module, and transmit the sensed data to the data processing unit, further improving the sensing efficiency.

[0024] 3. The data transmitted from the sensing unit can be analyzed through the data processing unit. When the data is transmitted, the data is first collected and processed by the acquisition module. The collected data enters the data fusion module, and the data fusion module performs fusion analysis and processing on the collected data. When the data reaches the point where the movement of the mechanical active component covering the electronic skin needs to be stopped, the data fusion module transmits the data to the data transmission module, and then proceeds to the next step, so that the efficiency of data processing can be improved, and the sensing data can be processed in a timely manner;

[0053] When the main body 1 of the mechanical movable component covered with the electronic skin 12 is working, when an obstacle is encountered in the surrounding area, the distance between the mechanical movable component 1 covered with the electronic skin 12 and the obstacle is sensed and processed through the infrared sensing module and the pressure sensing module, so that the distance of the obstacle can be sensed in time, and the distance between the obstacles is accurately controlled by the infrared sensing module, which further improves the working efficiency of obstacle sensing.

When the data is transmitted, First, the data is collected and processed by the collection module, and the collected data enters the data fusion module. The data fusion module fuses and analyzes the collected data. When the data reaches the point where the movement of the mechanical active component 1 covering the electronic skin 12 needs to be stopped, the data fusion module transmits the data to the data transmission module, and then proceeds to the next step, so that the efficiency of data processing can be improved, and the sensing data can be processed in time. Through the perception control unit 4, the movement of the mechanical active component 1 covering the electronic skin 12 can be controlled. When the data processing unit 3 transmits the processed data, the data processing module further analyzes the data, and the analyzed data is transmitted to the control module.

After the electronic skin 12 completes the perception, the data processing unit 3 processes the distance of the obstacle and the like. When the appropriate distance is reached, the data processing unit 3 can transmit the data to the perception control unit 4, so as to control and process the mechanical active component 1. When the mechanical active component 1 does not collide with the obstacle, the electronic skin 12 can control the mechanical active component 1 to stop moving in time to avoid the collision between the mechanical active component 1 and the obstacle, thereby causing damage to the mechanical active component 1 and the electronic skin 12, further improving the electronic skin 12's ability to sense obstacles, increasing the safety performance of the mechanical active component 1 during movement, greatly improving the application ability of the electronic skin 12, making the electronic skin 12 more widely used, and avoiding the mechanical active component 1 from being unable to sense obstacles in time during movement.
