Abstract:
1. Method for measuring or calibrating a position of an object in space using an apparatus having a frame, a platform to which the object is attached, a plurality of sensors, and a plurality of moving arms, each moving arm of the plurality of moving arms mounted to the frame at one end and to the platform at another end, the method comprising: driving the object attached to the platform across an operating space using a drive that is attached to or integrated into the object; sensing relative angular positions of individual members, the individual members including each moving arm of the plurality of moving arms, the frame, and the platform; and determining the position of the object or calibrating the position of the object using sensed, relative angular position data measured during movement of the object attached to the platform, the sensed, relative position data include a number of discrete data that is greater than a number of degrees of freedom of the apparatus.
