ArtBotics is a fun way for students to mix art with robotics. You can use Arduino, NXTs, EV3s, and more.
UMass at Lowell has several YouTube videos like this compilation and also this ready-to-use project guide .pdf

Here are a few other links that have inspired our teams to create artbotics projects like the one in the video above. Once you go to one of these, you'll find many more videos on the subject.
