Optimal control problems for robotic manipulator motions on manifolds are investigated. The most challenging problems are time-optimal motions of redundant manipulators subject to control and state constraints. Combining new transformation techniques with recursive modeling approaches and efficient algorithms, a numerical treatment of these complicated problems becomes possible for the first time. The numerical realization is based on an indirect approach. As an example, minimum-time and minimum-energy trajectories of a four-link robot are calculated. For the first time, even state constraints are exactly handled for this type of problems.
