Robotic lift device with human interface operation

An operator controllable robotic device, comprising:

• a support member;
• an upper robotic arm having a proximal end coupled to the support member and having rotational movement in at least one degree of freedom relative to the support member;
• a lower robotic arm having a proximal end coupled to a distal end of the upper robotic arm and having rotational movement in at least one degree of freedom relative to the upper robotic arm;
• a control arm to allow an operator to control the robotic device, the control arm having an extension member with a proximal end coupled to the upper robotic arm, and an operator interface located at a distal end of the extension member, the extension member extending from the upper robotic arm at a location such that the control arm and the upper robotic arm approximate an elbow joint of the operator, the control arm having rotational movement in at least one degree of freedom relative to the upper robotic arm, wherein the control arm allows the operator to interact with the robotic device such that a movement of the operator controls a movement of at least one of the upper robotic arm and the lower robotic arm;
• and
• a control system that controls a movement of the upper robotic arm and the lower robotic arm, wherein the control system utilizes a control scheme to move the upper robotic arm that is different than a control scheme to move the lower robotic arm.
