Touch-driven robot control using a tactile Jacobian

An experimental study on touch-driven robot control, or tactile-servo, is presented in this paper. The tactile servo scheme uses a tactile feature Jacobian matrix to relate the differential change in tactile feature space to that in the robot task space. Tactile Jacobian matrices are constructed through a finite element (FE) model of the tactile sensor. Detailed implementation of the control scheme and experimental results are presented.
