Haunted House Algorithm

A robot has to walk through a haunted house and collect 3 pieces of candy without touching a ghost. Write the exact steps (an algorithm) it should follow.

Draw a 4x4 grid. Put a start square, 3 candy squares and 2 ghost squares on it.
Write a list of moves using only: forward, turn left, turn right, grab.
Trade lists with a partner. Follow their steps EXACTLY, like a computer would.
Did the robot get all 3 candies? If not, find the bug and fix it.

Level up: Grades 3-8: Can you shorten your list using a repeat? Example: repeat 3 [forward].
