Consider a robot with two simple manipulators, as shown in figure ??. Manipulator A is a square block of side 2 which can slide back and on a rod that runs along the x-axis from x = −10 to x = 10. Manipulator B is a square block of side 2 which can slide back and on a rod that runs along the y-axis from y = −10 to y = 10. The rods lie outside the plane of manipulation, so the rods do not interfere with the movement of the blocks. A configuration is then a pair(x, y) where x is the x-coordinate of the center of manipulator A and where y is the y-coordinate of the center of manipulator B. Draw the configuration space for this robot, indicating the permitted and excluded zones.
