After spending so much time building robots, wouldn't it be nice to sit back and play some games... with your NXT! This week's inspiration is to make a game using the NXT. This could be a video game using the NXT display screen and sensors/motors for controls, but it could also be a more mechanical robot, such as a pinball machine.
Some nice examples of robotic games include this Helicopter video game and this pinball machine. There's also a very extensive tutorial on making NXT video games here.
P.S. You can see other posts in this series here.
