The designer of a polar configuration robot is considering a portion of the manipulator consisting of
\r\na rotational joint connected to its output link. The output link is 25 in long and the rotational joint
\r\nhas a range of 75°. The accuracy of the joint-link combination, expressed as a linear measure at the
\r\nend of the link which results from rotating the joint, is specified as 0.030 in. The mechanical
\r\ninaccuracies of the joint result in a repeatability error = ±0.030° of rotation. It is assumed that the
\r\nlink is perfectly rigid, so there are no additional errors due to deflection. (a) Show that the specified
\r\naccuracy can be achieved, given the repeatability error. (b) Determine the minimum number of bits
\r\nrequired in the binary register of the robot's control memory to achieve the specified accuracy.
