Motion limits are physical limitations set up to limit joint motions.

Motion limits are physical limitations set up to limit joint motions.

• A. True
• B. False
• C. Only for joints
• D. Variable

Answer: (A)

Motion limits are physical constraints that cap how far a joint can move, placed to keep motion within a designed, safe envelope. They act as hard stops or mechanical features that physically prevent overtravel, protecting the structure and nearby people or equipment. In practice, you’ll often see hard stops at the extremes of a joint’s range, sometimes complemented by software soft limits that stop commanded motion before hitting the hardware stop. The statement is true because it describes how these limits function: they are tangible barriers intended to prevent excessive joint motion and thereby reduce risk of damage or harm. While software limits can also play a role, the existence of physical limits is the defining part here.
