That's neat. I was wondering when someone would do this. The technology has been there for years (Roomba has been out for what, seven years now? Correct me if I'm wrong). I had an idea of doing this last year with an old Roomba Disco, but I didn't know of a way to remotely control from 150 feet away. BTW, robot modifiers, if you don't want to wait around for this to hit the market, you can create your own with an old Roomba Disco or Create (if you use a Roomba, be sure to remove the cleaning head, side brush, and dust bin and that it has the right firmware for Rootooth drive) Swap out the regular drive tires with high traction tires. Add on the shovel attachment, which will have to be custom made. Find a Rootooth, a Bluetooth transmitter for your computer if you need one, maybe an actuator or servo to lift the shovel so that the robot can use a home base to charge, Roomba Status software, which can be found here: viewtopic.php?f=4&t=6941&hilit=
, and if the back of the Roomba tends to lift up, you may either remove the springs on the drive tires or add weight to the back of the Roomba. Covering the Roomba's body with thin plastic covering would provide snow and rain protection (where I live, it can rain while there is snow on the ground).
