Abstract

A modified weighted gradient projection method is presented for the optimization of kinematics of redundant robotic manipulators. The method utilizes the matrix weightability measure and the self-motion declinability measure. By these means the weighting matrix and the self-motion amplitude can be determined from the homogeneous solution. Because the optimization method is based on a least-norm solution, it can obtain optimal solutions at low joint velocities. This characteristic has been verified by simulation
