Abstract
The paper deals with the problem of optimal trajectory planning for rigid links industrial manipulators. According with actual industrial requirements, a technique for planning minimum-time spline trajectories under dynamics and kinematics constraints is proposed. More precisely, the evaluated trajectories, parametrized by means of cubic splines, have to satisfy joint torques and end-effector Cartesian velocities within given bounds. The problem solution is obtained by means of an hybrid genetic/interval algorithm for semi-infinite optimization. This algorithm provides an estimated global minimizer whose feasibility is guaranteed by the use of a deterministic interval procedure; i.e., a routine based on concepts of interval analysis. The proposed approach is tested by planning a 10 via points movement for a two link manipulator.
