This document discusses the workspace design of robots. It defines key robot terminology like degree of freedom (DOF) and provides examples of different joint types and their DOFs, such as pin joints with 1 DOF and ball and socket joints with 3 DOFs. It then explains how to understand a robot's workspace using the example of a cylindrical robot with 3 DOFs (linear motion along z and y axes and rotation along z-axis). The workspace is formed by tracing the path of the end effector as it moves through its range of motion. Understanding the robot's workspace is important to avoid collisions when programming motions in industrial environments with multiple robots and components.
