Tellybots aren't been made anymore :-\ but they're the best looking bot in my opinion 8). is anyone willing to recreate a tellybot and reprogram it for robot streamer? it's design is posted online somewhere.
It's an open design, so might be on the internet somewhere. I don't know of anybody who would make one, and they are pretty complex to build.
Practically I'd say just use a bumperbot for most people.
