The work envelope is defined as the maximum reach of the robot.

• A. The rear clearance area around the robot
• B. The minimum safe distance to obstacle
• C. The total operating time of the robot
• D. The maximum reach of the robot

Answer: (D)

A robot’s work envelope is the space the robot can reach with its end effector, determined by the lengths of its links and the limits of its joints. The defining feature of that envelope is the maximum reach—the farthest distance the arm can extend from the base. This maximum reach sets the bounds of where tasks can be performed, which is why it best describes the work envelope in safety and systems contexts. The rear clearance area is about space behind the robot and avoiding collisions in that direction, not the overall reachable space. The minimum safe distance to an obstacle is a safety margin, not the extent of reach. The total operating time concerns how long the robot can run, not where it can reach. So the work envelope aligns with the maximum reach.
