The robot work cell includes the robot and any external devices that interact with it during normal operation.

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

Answer: (B)

Defining the work cell boundaries around a robot means including the robot itself and any external devices that interact with it during normal operation. This matters because safety analyses, safeguarding, and control logic are built around the entire integrated system, not just the robotic arm. External equipment that routinely interacts with the robot—such as conveyors, fixtures, end-effectors, sensors, and safety devices—must be considered part of the same environment so that protections cover all potential hazards and motion paths. Therefore, the statement is true, since the work cell is defined to include both the robot and the external devices that interact with it during normal operation. If a device doesn’t interact during normal operation, it wouldn’t be included in the cell, but those that do interact are included.
