Abstract: A rotary positioning system configured to provide absolute referencing is provided. The rotary positioning system includes an encoder mounted on a motor shaft of a motor and configured to generate an index pulse corresponding to a complete rotation of the motor shaft. The rotary positioning system also includes a speed reducer coupled to the motor shaft and configured to reduce a rotary motion of the motor by a pre-defined ratio and an output drive shaft coupled to the speed reducer and configured to transfer the reduced rotary motion to a load. The rotary positioning system further includes a sensor mounted on the output drive shaft of the speed reducer and configured to determine an absolute orientation of the output drive shaft and a controller coupled to the sensor and configured to generate a correlation function of the absolute orientation and the index pulse count.

Abstract: A hybrid robotic manipulator adapted to move objects includes a base and a waist mounted on the base. The waist is configured to rotate on the base. The hybrid robotic manipulator further includes a pair of arms mounted on the waist. Each arm includes an upper arm, a forearm serially coupled to the upper arm at an elbow, and a wrist configured to couple the pair of arms at a distal end through a pair of connecting elements. The wrist further includes an end-effector mounted thereon and configured to grip the object and move the object to a desired position.
