摘要
This paper focuses on the inverse dynamics formulation of manipulators that is suitable for parallel computation, and a corresponding nonrecursive Newton-Euler formulation is presented. In order to illustrate its potential parallelism, a simple parallel scheduling scheme is proposed, and the parallel computational efficiency for the inverse dynamics of the basic three Links of a PUMA 560 robot is analyzed. Compared with other algorithms, the theoretical computation cost of this parallel algorithm, in which factors such as communications overhead are ignored, is smaller.
