[0027] DETAILED DESCRIPTION: Take the intravenous injection operation incorporating tactile perception as an example, such as Figure 4 , its working principle is as follows: after the patient's body surface is sterilized, the position of the basic needle entry point is determined, and then the present invention is moved to the vicinity of the needle entry point through the control of the robotic arm, and the surface of the gel elastomer 20 of the touch sensor 1 is in contact with the body surface. , the image of the contact surface is captured by the camera 18 and transmitted to the computer for analysis, and then the position of the subcutaneous blood vessel is accurately sensed. When it is determined that the position of the needle insertion point is at the center of the gel elastomer 20, the screw motor 6 is powered on to drive The screw 8 rotates, thereby controlling the needle 17 to perform linear motion, extending out and passing through the tactile sensor 1, and piercin...
