Meet Kamigami: an origami robot that teaches your kids a thing or two about technology. The robot is easy to assemble and can be controlled using a smartphone. You can build these robots in under an hour. You get a drag & drop interface to change how the robot behaves. These robots are packed with sensors and support robot-to-robot communication.
The above video gives you a better idea how these robots work. You can support this project on Kickstarter.
