Abstract
We investigate the computational needs of advanced real-time robot control. First, sampling rate issues in the control of nonlinear systems are discussed. Second, a representative nonlinear robot control algorithm using an explicit robot dynamical model is derived. Some typical terms of the exact equations are given for two industrial robot arms. Third, we define some performance criteria of interest in realtime control. Finally, we compare a variety of implementations of the above control algorithm on a network of INMOS Transputers.
