Class #3: Configuration Space of a Robot
________________________________________________________________________________________________________________

The 3 drawings on the left shows two representations of the configuration space of a 2-revolute-joint arm: a torus and a square. The drawings on the right illustrate the mapping of workspace obstacles into the configuration space.
