Differentiate offline programming from online/teach pendant programming.

• A. Offline programming creates and tests robot programs on a computer (simulation); online/teach pendant programming edits code directly on the robot in real time.
• B. Offline programming uses the robot to teach themselves.
• C. Online programming cannot be tested.
• D. Offline programming is performed on the robot in real time.

Answer: (A)

The main idea is where the robot program is created and tested. Offline programming means you build and test the robot program on a computer, often using a simulation, before loading it to the actual robot. This lets you rehearse motions, check speeds, verify reachability, and catch errors in a safe, controlled environment without risking hardware or production downtime. Then, once the program is proven, you transfer it to the robot controller for execution.

In contrast, online or teach pendant programming involves editing or teaching the robot directly on the cell, often in real time, using the robot’s pendant or a live interface. This approach is useful for quick adjustments or hand-guided teaching but carries more risk since changes affect the real robot immediately and require careful monitoring.

So, the correct description emphasizes developing and testing on a computer (with simulation) versus editing directly on the robot in real time.
