The reverse module enables the rollbar manipulator to move laterally, increasing the workspace.

The reverse module enables the rollbar manipulator to move laterally, increasing the workspace.

• A. False
• B. True
• C. Sometimes
• D. Not related

Answer: (B)

Adding a component that provides motion along a new direction increases the robot’s reachable area. The workspace is all the positions the end effector can reach given the mechanism’s joints and their limits. A reverse module that lets the rollbar manipulator move laterally adds a horizontal axis, so the end effector can reach locations it couldn’t before. This expands the set of possible positions, meaning the workspace grows. If the lateral motion has limited range or is blocked by other parts, the increase is smaller, but the basic idea holds: introducing lateral movement expands reach. Hence the statement is true.
