Pretty neat!
I have a couple of "dead" Roombas that at some point I am going to hack on at some point (I've always thought iRobot should sell the drive wheel assemblies; those have some impressive engineering); my wife and I bought one from a Pic-N-Save (oops, sorry - I meant "Big Lots!") a few years back, then it "died" (wouldn't run anymore for some reason), so we got a newer model.
Later I found another at a Goodwill for $20.00. It worked "somewhat", but its optical bump sensors had failed, so it went around by "touch"...
We named it "Helen". :
Eventually it stopped working altogether, and now we just have a single Roomba (a 500 series - 560, IIRC) cleaning our house.
Both of the dead Roombas are in my shop on a shelf waiting for their day in the sun again; I am actually planning on pulling one down and doing everything I can to get it to work so that it can become my "shop floor cleaner"; my floor in my shop is bare concrete, so it gets dusty fast, plus there's always stripped wire bits to collect. I am thinking of it as my hacked "Shop Dawg"...
I might just graft an Arduino on the thing...
