C.H.R.1.S. follows the instructions given to him, moving forward, left and right to reach each desired destination.   This is a great introduction to coding, as he moves with each command. He is totally controlled by you as you guide him on each travel adventure, while you are practising and learning some great logic and problem solving skills. The block sequence is basically programming your robot. You are telling him which way to move (literally putting the ideas in his head, or rather his helmet!).
