Robotic Wrist
Client:
Barrett Technology, Inc.

Description:
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.
