Examples are processes like water-jet cutting, composite fiber placement, and robotic sealing. For high dynamic trajectories, a redundant manipulator consisting of a low bandwidth macro-manipulator and high bandwidth mini-manipulator can preserve the high dynamic trajectory requirements while maintaining the large work envelope of the macro manipulator. My talk presents an efficient global solution to the redundancy resolution problem, with the goal of minimizing the integral jerk of the actuators. Minimum jerk trajectories are advantageous for minimizing structural oscillations and improving the smoothness of control. The method presented achieves up to 75% reduction in integral jerk and 98% reduction in peak jerk vs. a greedy approach, while being embarrassingly parallel making it suitable for a high performance computing implementation. Additionally, a simple real-time controller is presented that maintains the planned low jerk trajectories given task-space feedback on the trajectory following error.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EPhil Freeman is a technical fellow with Boeing Research and Technology.
