Here is a set of robotic modules that teach kids a thing or two about coding. The ioCube magnetic construction kit supports drag & drop programming with Blockly. You can use them to build a remote controlled car or interactive games. You get a laser rangefinder, battery, 8×8 LED matrix, and LED controller module.
ioCubes support Bluetooth and WiFi. Advanced users can customize these modules with interchangeable panels. You can find out more on Kickstarter.
