Robotic system with intuitive motion control
A robotic system includes a base with a manipulator is attached to the base. At least one sensor is associated with the manipulator. The at least one sensor detects a trajectory of an external disturbance on the manipulator or an external cue from a user. A controller is provided that converts the trajectory detected by the at least one sensor to an input signal or the external cue detected by the at least one sensor to an input signal. A drive system receives the input signal, and in response to the input signal powers the base or to power the base in a trajectory corresponding to the external cue. A method for intuitive motion control of the robotic system is also provided.
