We've seen all manner of phones controlling robots, cars and helicopters, but a HTC Hero operating a Lego Mindstorms robot? Awesome. It works via a purpose-built app which uses the Hero's accelerometer, connecting to the 'bot over Wi-Fi.
It's from the creative minds at Swedish tech company ENEA, who created the app to harness the Hero's accelerometer to control the Mindstorms bot. Normally such a relationship between a controller and robot would be over Bluetooth, but ENEA was forced to use Wi-Fi due to the "limited Bluetooth support in Android OS version 1.5 (not supporting the Bluetooth serial port profile, SPP)".
