This program is for the Goal Keeper model that can be built with the WeDo Lego robot kit: https://a248.e.akamai.net/cache.lego.com/r/education/r/lesi/-/media/lesi/downloads/building%20instructions/wedo/9580_goalkeeper.pdf You can see a video of him in action here: https://vimeo.com/130042297 Use the left and right arrow keys to move the goalie. When a ball is kicked through the goal, a trumpet will sound, and one will automatically be added to the score. If the keys move the the goalie in the wrong direction, just keep going until the lever moves to the top side.
