Test the HEXBUG out on a flat table, see how it moves and how fast it travels.
Once you have seen the HEXBUG move, block it off with an object and see how it bounces off the object to find a new path.
Once you have seen the HEXBUG in action, it’s time to start making a simple maze for it to travel round. As the you make the maze, try to make the path as complex as possible so that the HEXBUG has to really ‘work to get from ‘A to B”.
