Barrett engaged an external project team to redesign its
3-dgree-of-freedom cable-driven robotic wrist for weight reduction and improved
electromechanical performance. As a subassembly for a Whole Arm Manipulator™,
the robotic wrist experiences high dynamic loads yet must provide low inertia
for forced feedback control. Using magnesium and carbon fiber components a
weight reduction of 49% was achieved, while maintaining structural stiffness and
strength of the previous design.
