Which debugging approach is recommended on the Teach Pendant?

• A. Use pause/breakpoints, step execution, and verify sensor state and I/O.
• B. Edit random lines and run without checks.
• C. Only rely on error messages without stepping.
• D. Disable all safety features to speed up debugging.

Answer: (A)

Using pause or breakpoints, stepping through the program, and verifying sensor state and I/O is the best way to debug on the Teach Pendant. This approach lets you halt execution exactly where you need, watch how the code flows line by line, and confirm that hardware signals match what the software expects. Breakpoints give you control to inspect variables and conditions at critical moments, while stepping through shows you how decisions are made and where things diverge. Checking sensor readings and I/O ensures the robot’s inputs and outputs behave correctly, so you aren’t chasing issues that only appear when hardware signals are different from what the software assumes.

Other methods are risky or uninformative: editing random lines and running without checks can create new problems or unsafe states; relying solely on error messages doesn’t reveal how the issue occurred or where the logic went wrong; and disabling safety features to speed debugging can cause dangerous robot behavior and is not appropriate practice.
