Assignment:
The revolving joint (type V) of an industrial robot has a range of 240° rotation. The mechanical errors in the joint and the input/output links can be described by a normal distribution with its mean at any given addressable point and a standard deviation of 0.25°. Determine the number of storage bits required in the controller memory so that the accuracy of the joint is as close as possible to, but less than, its repeatability. Use six standard deviations as the measure of repeatability.
Provide complete and step by step solution for the question and show calculations and use formulas.
