I know the Roomba vacumn has an automatic recharge feature which is very cool. However I would like to have my robot when is is hungry to feed itself. Has anyone come up with a solution to this yet. I have been reading a lot of posts but this one I have not seen.

EZ-B connects to it and can control dock seeking
I haven't done a dock seeking robot... Outside it won't work because it is Infrared. But inside you can use the guts of a roomba.
As for an outside dock seeking robot.. Hmmmmmmmmmmm, that's a good question. Some kind of beacon would be necessary. GPS can be "almost" accurate enough to at least get your robot into the area of the charging station.
The rest woudl be a bit more work
You cauld have the robot follow a buried wire . connect the wire to a audio amp (old radio) ,it will pulse to the music .
mount two coils or guitar pickups to the front of the robot and have it line follow straight to the charger.
PS use gps to get to the area of the charger and then pick up the cable for final nav .
