The variable time delay of the network is a key problem which affects the stability of teleoperation. The composing theory of the telerobotics with the test result of the network delay is introduced. The RBF neural network is applied to predict the delay. A new predictive controller based on the RBF neural network and the Smith predictive controller is proposed to eliminate the real delay. Simulation results from MATLAB show that the control scheme is effective and robust.
