The restrictive space and the operating space always refer to the same space in a robot's work environment.

• A. True
• B. False
• C. Not Applicable
• D. Not Sure

Answer: (B)

Operating space is the volume in which the robot is designed to operate during normal tasks, defined by its reach and allowed motions. Restrictive space describes zones where movement is constrained for safety or practical reasons—areas the robot should avoid or enter only with safeguards, speed reductions, or interlocks. These are not the same; restrictive space can lie inside, outside, or overlap with the operating space depending on how safeguarding is configured. So the statement is false because the two terms refer to different concepts in robot safety and task planning.
