General Algorithm for Automatic Generation of the Workspace for n-link Planar Redundant Manipulators

Abstract

An efficient algorithm to simulate the workspace for a n-link redundant manipulator with rotating base is developed. The unique feature of the algorithm is its ability to automatically generate the binary angle selection code for the given manipulator. This code system makes it possible to avoid repetitions in calculating positions and plotting arcs for the workspace and thus saves considerable computing and graphic time. Two types of workspace are possible using this algorithm. Numerical examples including the workspace of human arm motion and that of a 20-link system are demonstrated to illustrate the effectiveness of the algorithm.
