The invention discloses a mechanical arm
obstacle avoidance method based on an EIT
tactile sensor, and belongs to the technical field of
robot tactile perception. Firstly, tactile information is obtained through an EIT
tactile sensor, and a tactile sensing image is reconstructed; then, the visual module starts to detect the target object and the box, if the visual module does not recognize the target object, the target object is fed back to the control module, and the
tail end of the mechanical arm is controlled to move to the next area until the whole
workbench is traversed; if the target object and the box are detected, obtaining a target position and a placement position through coordinate transformation; after the
tail end of the mechanical arm moves to a target position, a target object is clamped through a clamping jaw, and then the mechanical arm moves to a placement position; in the moving process of the mechanical arm, an obstacle touches the mechanical arm, the EIT
tactile sensor detects the change of the
conductivity of a sensing area, and the position of a change center point is converted to the position below a mechanical arm base
system and transmitted to the control module to re-plan a
route; and finally, the mechanical arm touches the obstacle for multiple times during movement, and the control module enables the mechanical arm to bypass the obstacle and reach the target object placement position through multiple
route plans. According to the method, the obstacle model can be actively sensed and established, and a
safer and more reliable
obstacle avoidance route can be planned.
