Android controlled LEGO Mindstorms robots

I’ve come across numerous Android controlled vehicles in the past, but never a LEGO Mindstorms robot, let alone two. The folks at ENEA in Linköping, Sweden, built a pair as a trade show demo. One of the main challenges was getting Bluetooth support to work. They ended up using an Ubuntu laptop to tunnel between devices. Of interest is the fact that the Android phone controls more than one device. [Thanks, Phil!]
