Gravitationally decoupled actuation

WebAug 1, 2014 · It means that during the support phase, there is at least one actuator that, at the same time, is moving and withstanding the weight.On the contrary, in gravitationally decoupled (GD) legs, the moving actuators do not bear the weight,and theoretically, no power is expected during the stance phase of GD legs due to the robot weight. WebThe gravity decoupling drive mechanism was employed to maximize the energy efficiency of the robot system [81]. Furthermore, the two methods can be integrated and applied to the posture control of...
