Troubleshooting Step 2

When retracing a programmer’s steps it’s a good idea to collect some data.

  1. Load the program and press the play button.
    What does Edison do? ___________________________________________________________________

  2. Does Edison do what you expected? Why or why not? ___________________________________________________________________

  3. Now press the triangle button. The robot will start spinning right. Why does this happen? ___________________________________________________________________

Sample Answers

  1. The robot is spinning left slowly. 
  2. Yes, because that is what the first block inside the loop tells the robot to do. 
  3. The robot starts spinning right because the condition of the ‘spin left’ block has been met, and so the robot moves on to the next block in the program which is ‘spin right’.
