How it works
A robot does only the steps it is given, no more and no less.
A robot cannot guess, so it needs clear steps.
A bug is a mix-up in the steps. We fix the steps and try again.
Worked examples
Not clear
- Grandpa says, go over there.
- Nia does not move, because over where?
- A robot cannot guess, so it needs a clear step.
Clear steps
- Take two steps forward. Turn around. Take three steps.
- Each step is clear, so Nia can do it.
Steps on a board
- Nia tells Bo: forward three times, turn left, forward twice.
- Bo walks the dotted way and lands on the star.
- A step that walks Bo into a rock would be a bug.
