ABSTRACT:
A robotic arm and control system comprising a multi-axis, open-loop system of coupled structural members, wherein each structural member is pivotably coupled to one another to form a number of joints, wherein position calibration is provided by way of position sensors disposed at each joint, and controls for manipulating each joint in a predetermined manner and for monitoring the output of each position sensor, the controls first causing all structural members to move with respect to one another so that each position sensor outputs a home signal, the controls then manipulating each structural member in a predetermined sequence until each structural member is caused to be within a predetermined distance from its home position.
