Abstract
An intelligent power assisted manual manipulator controllable by operator inputs from an operator for moving an object is provided. The manipulator includes a movable base supporting a lift mechanism for moving the object. The manipulator also includes at least one servomotor for actuating at least one of the movable base and the lift mechanism for moving the object. An operator control mechanism for receiving the operator inputs is supported on the lift mechanism. A plurality of force sensors are disposed between the operator control mechanism and the lift mechanism for sensing said operator inputs and actuating at least one of the at least one servomotor. The movable base includes an overhead rail defining a generally horizontal first axis and a carriage supported on the overhead rail and movable along the first axis. The lift mechanism includes a turret assembly supported on the carriage having a generally vertical second axis, and a generally horizontal third axis. The carriage has first and second elongated portions in opposing generally horizontal planes and third and fourth elongated portions in generally vertical planes. Oversize rollers on unhardened ways support the carri…
