Embisys has an Internet connected LEGO robot. What makes this a little different is the Nokia cell phone, which passes all the data via a mobile packet data service to an Ajax based web page. It can send pictures & receive commands anywhere there is a cellular signal.

TeMo is a tele-operated mobile Internet robot. While other Internet robots mostly use WiFi (or a nearby PC with an Internet connection), TeMo connects to the internet using Mobile packed data services (e.g. GPRS / EDGE / UMTS / HSDPA). The advantage is virtually unlimited mobility for the robot.
