If you missed out on the sphero, then this may be a good alternative for your kids to code and build a robot.
Specs:
Enjoy learning about programming, electronics and robotics in a fun interactive way. Inspired by Scratch coding, mBot is an easy-to-assemble gadget with Bluetooth connectivity.
Piece together the 38 pieces and use the colour-coded RJ25 ports to begin programming straight away. The mechanical body of the mBot is compatible with most Lego parts, while the electronic sections are based on the Arduino open-source ecosystem.
The drag-and-drop software provides an intuitive way for kids to learn programming. Soon you'll be able to control the robot and see it carry out small tasks. Transform your mBot into an obstacle-avoidance car, line-following vehicle or remote control car. You can also use mBot to play multiple games like balloon bursting game, soccer playing, sumo and more.
