Abstract

The invention discloses a flexible three-dimensional force touch sensor of multi-fingered hands of a human-simulated robot and a three-dimensional force detecting system, relating to the field of touch sensors of robots. The invention aims at solving the problem that more touch sensors only can acquire normal force but can not detect the normal force and the force simultaneously like the human hands. A sensor body consists of a force-transferring hemispherical layer, a flexible top-level electrode layer, a composite material QTC (Quantum Tunneling Composites) with quantum channel effect and a flexible bottom-level electrode layer which are arranged in sequence from top to bottom; a signal acquisition circuit consists of a mixed-signal array programmable on-chip system and an analog multiplex selection module; the on-chip system comprises a digital logic module, an analog digital conversion module ADC, a digital analog conversion module DAC, an analog signal register I, an analog signal register II, a voltage amplifying circuit and a multi-way switch; and the analog multiplex selection module comprises an analog multi-way switch I and an analog multi-way switch II. The invention is used for the touch sensor for detecting the three-dimensional force of the multi-fingered hands of the human-simulated robot.

Description

Technical field [0001] The invention relates to the field of robotic tactile sensors. Background technique [0002] The tactile sensor is an indispensable means for the multi-finger hand of a humanoid robot to obtain contact information. According to the information provided by the tactile sensor, the multi-finger hand of the humanoid robot can reliably grasp the target object. The unreliable grasping caused by the inability to obtain contact information when the humanoid robot multi-fingered hand grasps objects will bring great danger. Most of the existing humanoid robot multi-finger tactile sensors can only detect the normal force, but cannot detect the tangential force. However, the detection of tangential force plays an important role in the reliability of grasping. In addition, the humanoid robot multi-fingered hand tactile sensor requires that the tactile sensor has a high degree of flexibility and miniaturization, which can conform to the surface of the finger and be int...
