What is teach pendant programming, and what are typical limitations compared to offline programming?

• A. Offline simulation of robot programming.
• B. On-line manual teaching by moving the robot; limitations include slower programming, human error, limited repeatability, and less optimal paths.
• C. A software tool for post-analysis.
• D. A hardware diagnostic tool.

Answer: (B)

Teach pendant programming is an on-line, manual method where an operator uses a handheld pendant to jog the robot through motions and record those positions to build a program. This approach lets you quickly teach simple tasks by guiding the arm to key points and saving them as waypoints. Why this is the best description here: it captures both the method (on-line manual teaching by moving the robot) and the common drawbacks when compared with offline programming. Because the program is created step by step by a person in real time, it tends to be slower to produce, more prone to human error, and the recorded positions can vary between runs, giving limited repeatability. The paths and timings are often not as optimized as what a computer-based offline planner could generate, which aims to optimize speed, smoothness, and collision avoidance. Contrast with the other ideas: that view describes offline or post-analysis tools or hardware diagnostics, not the live, manual teaching process used with a teach pendant. Offline programming uses simulations and computer-based optimizations rather than hands-on teaching with the pendant.
