Which term describes the three-dimensional space within which a robot can operate?

• A. Work envelope
• B. Work cell
• C. Reach zone
• D. Operating space

Answer: (A)

The work envelope is the three-dimensional space a robot can reach and operate within, determined by the lengths of its links, the configuration of its joints, and the limits of each joint. It’s the volume that contains all the positions and orientations the end effector (like a hand or a tool) can achieve given the robot’s kinematic structure. This concept is crucial for planning tasks, ensuring the robot can reach required positions, and for safety and collision avoidance during operation. Work cell refers to the physical area and surroundings where the robot and its tools are installed, including fixtures and safety boundaries—not the reachable space itself. Reach zone is not a standard term for this concept, and operating space is a broader, less precise phrase that doesn’t specify the robot’s actual reachable volume.
