Here is another educational kit that gets your children familiar with robots and coding. Robo Wunderkind is a robotics kit that lets you build your own robot. You get a bunch of blocks you can connect to build various robots. There is a visual programming interface available for the robot.
Your robots can drive around, play sounds, react to noises, record messages, follow sources of light, solve mazes, and a lot more. The companion app will be available for iOS and Android devices. More information is available on Kickstarter.
