One of the axes of an RRL robot is a sliding mechanism with a total of 0.70 m (about 27.5 in.). The robot's control memory has a 10-bit capacity. In addition, it has been observed that the mechanical inaccuracies associated with moving the arm to any given programmed point form a normally distributed random variable with the mean at the taught point and the standard deviation equal to 0.10 mm (about 0.004 in.). Assume that the standard deviation is isotropic (it is equal in all directions). By definition, three standard deviations include "all" of the mechanical errors in the arm movement. With these definitions and assumptions, determine the following:
(a) control resolution
(b) spatial resolution
(c) accuracy
(d) repeatability for the robot.
