Hi i'm back with BLUE STORM3R player number 3. You control this robot withe IR sensor because if you programmed this robot to go on its own it might score a goal in its own net. The colour sensor is used for detecting the white line so it doesn't go out of the field. the touch sensor is used for detecting when it has the ball. To pass when your team mate is ahead of you, you slow down with the ball go backwards turn right or left go forwards a bit turn right or left go forward then hit the ball.the medium motor powers the arm that passes and catches. Be sure to look for BLUE STORM3R number 5 hope you like it.
