Children were given a lego maze and a marble.  Using their prior knowledge and skill set pupils had to program the joint module to get the marble around the maze, from the start to the end point. Children had to combine both the X and Y servos together to achieve the angle needed to make the ball roll in the correct direction. 

Pupils needed to break down the task into sections, then constantly run, test and debug their program. 

This lesson required resilience, collaboration, logical thinking, testing and de-bugging.
