Abstract
A manipulator having at least two segments, rotatable with respect to each other, measures the angle formed therebetween and is self calibrating to insure the accuracy of the measurement. An electrical resolver is employed, with its rotor attached to one of the segments and stator attached to the other, with the rotor and stator slotted, in registration, at a relative position indicating electrical zero. Each segment has a pin formed on it positioned to engage the slots in the rotor and stator at a mechanical zero degrees output, insuring a zero degrees mechanical output for zero volts electrical output.
