Abstract: As the development of robot technology, the need for safety in robotic systems is of growing importance. A low-cost, flexible three-dimensional force sensing array based on conductive rubber is presented with application as artificial skin for robot. In this paper, the structure of a three-dimensional force flexible tactile sensor has been improved. The flexible sensor based on the pressure-sensitive conductive rubber can detect a three-dimensional force. Compared with the previous method, information of more nodes is considered in decoupling by using LM algorithm. The simulation indicates that the structure and the decoupling algorithm are feasible for the measurement of the flexible tactile sensor array.
