You can make your own SwarmBot, easily code it via Arduino GUI, do more experiments like this one, take photos for competition, or help update the installation procedure.
Swarm Robots is free fun for members! Membership is only 100Y per month!
We could do also lots of fun stuff for Barcamp (September 8) and Shanghai MakerFair (November 2-4)!
For example “show off” behaviours like follow the leader, find the “ball”, or draw pictures on floor. More ideas.
Regular Meetup Thursday night from 7pm, Other times are DIY or arrange with others 
Lots of info here!]]>

I am just wondering how it keeps balance with 2 wheels moving forwards and backwards .
It uses that upside down LED as a third wheel. That early prototype was a bit unstable and tended to tip a bit and we have since lenghtened the wheel base a bit to make it more stable.
