Hello everyone. I have a project I'd like to share with you. It's a WiFi controlled Lego robot with an onboard camera. With it I can drive around in my house (or any other place with WiFi) from anywhere on the world while sitting behind my laptop. A Processing (Java) applet displays the movement buttons. It sends movement commands to the WiFly shield through a socket connection. The Arduino then translates the command to an infra red signal which the Lego IR Receiver picks up to control the motors. A stripped wireless IP camera takes care of the video stream.
Video's, photos, schematics and source codes can be found on my website:http://brickbot.net/projects/wifi-lego-camera-robot
