Nothing will impress the neighbors at your next summer barbecue like emerging from the garage on an awkward, four-legged robot vehicle. Yes, Robot 3's R7 is the ultimate summertime accessory, featuring a comfy plush seat and four full legs of robot power. It doesn't move too quickly, which should be seen as a bonus rather than a disadvantage as it gives everyone on the block that much more time to watch you slowly amble by. Costing $5,250, the R7 may be a bit on the pricey side for a robot of questionable benefit, but you can't put a price on intimidation. And intimidated is just what the neighbors will be when the barbecue is over and you tell them to get the hell off your lawn from atop the R7.
