wild Roomba mods, but overall it's pretty much a low-to-the-ground affair -- unless you get the cats involved, of course. That's apparently changing, though -- check out this robotic grasping system, which can pick up foreign objects and deliver them to you at about waist height. The system was 95 percent effective in picking up objects of all sizes and shapes during trials, and it was apparently quite simple to build and code. Nice for a Roomba, sure, but we'd rather be partying with SOBEaR. Video after the break.
