We love phones and we love Lego, so we almost fell off our chairs when we found this video of an HTC Hero controlling a robot. The Hero is running an Android application written by Enea Linköping, a Swedish technology company which specialises in operating systems. The app works using the Hero’s tilt sensor to control the robot lego car and connects via Wi-Fi.
An Enea blog post explains how the Swedish engineers used their purpose-built application to send commands to a Lego NXT brick. Due to Android OS 1.5’s limited Bluetooth support (not supporting the Bluetooth serial port profile, SPP), Enea used the Hero’s Wi-Fi to send information to an Ubuntu Linux Laptop with a TCP/IP to Bluetooth tunnel (just a raw tunnel, no logic or programming).
