Robot that comes when called - kits
I know there are robots available which have sensors on them which allow them to roam around and return to their re-charging outlets - like the iRobot Roomba. I think it has sensors on it too so it can see where it's going and remember where it's been.
I'd like to make a simpler version of this where if I had a remote to call it, the robot would unplug itself and come to me and avoid furniture obstacles along the way. Does anyone know what components I need for this, or a kit, or a book with the how-to steps?
Thanks,
Bret
