Arduino & Fun Robotics for Children

I have made a open source wireless upload STEM robot which support line following, light seeking. Now share with you:

Designed for STEM education, Open Source! APP controlled, Arduino, supports Scratch, Bluetooth Upload. Let kids Play and Learn!
This robot kit has everything you need to get started. You can demonstrate many standard robot functions right out of the box. It's simple, easy to use and fun. 

Blinkgogo also comes with a hardware expansion board for those who really want to go wild when is comes to trying new things and developing new robotics systems.

The power of Arduino UNO + Bluetooth + Lego Blocks = Blinkgogo
