Experimental robot system composed of a 3-DoF finger robot and a 2-DoF trackball, which is used for controlling the car driving game. The trackball device was mounted in front of the robot. The horizontal position of the car was controlled by the lateral rotation of the trackball while the car was moved with a constant speed for the vertical direction. The combined state $q,q˙$ of the finger robot and trackball state were sent to the computation server every 10 ms. The SNN-MPC implemented on the server derived an optimal control signal $u$ for the next time step within 10 ms.
