The problem of scheduling the robot inverse dynamics computation consisting of m computational modules to be executed on a multiprocessor system consisting of rho identical homogeneous processors to achieve a minimum-scheduled length is presented. This scheduling problem is known to be NP-complete. To achieve the minimum computation time, the Newton-Fuller equations of motion are expressed in the homogeneous linear recurrence from that results in achieving maximum parallelism. To speed up the searching for a solution, a heuristic search algorithm called dynamical highest level first/most immediate successors first (DHLF/MISF) is first proposed to find a fast but suboptimal schedule.
