Force Sensorless Impedance Control of Dual-Arm Manipulator-Hand System
2011
Journal of System Design and Dynamics
Preserved Fulltext
Impedance control was designed for a three-fingered robot hand by using this estimated external force. ...
This robot is a dual-arm manipulator, and each of its end effectors is a three-fingered robot hand. Generally, a force sensor is used for recognition of external force on the fingertips. ...
Furthermore, our robot hand is equipped with a function to change the position of its two fingers using one actuator to grasp complex-shaped objects. ...
