Development of a three-fingered robotic hand-wrist for compliant motion

Discusses development of a multifingered hand-wrist mechanism for compliant motion. First, a procedure for the mechanical design is proposed, and details of the procedure are shown using a simple two-fingered hand. Second, a three-fingered hand with wrist is designed based on the proposed design procedure, and a force sensor is also designed. Then a three-fingered hand-wrist mechanism with fifteen DOF is manufactured. Finally, basic experimental results are described to investigate part of the performance of the developed mechanism and the force sensor
