John Evans on 18 Nov 16"The idea for this bot came from the book Robotics: Discover the Science and Technology of the Future. The specific project that motivated this activity was the Art-Making Vibrobot on pages 24 to 26, though I modified the supplies considerably and the technique slightly. Basically this little "robot" is just a cup with marker legs that vibrates and spins due to the motor being off balance. As it jiggles around on a piece of paper it makes interesting designs. While I hope to make more exciting and complicated projects with my kids as they get older, this was a nice unthreatening activity to start with which showed my child how to hook up a simple DC motor to a battery. He's already familiar with some of these electrical concepts through our Snap Circuits set (link to my review), but this was a fun, hands-on supplement to the more structured activities in that set."
