As marketers continue to search for (and exploit) places in which you'd never think to find an ad, it makes sense to scroll a few plugs through an item that the vast majority of us spend at least a few hours per week touching. That item, dear friends, is the handle of the tried and true shopping cart, and apparently, Modstream is hoping to install bars with scrolling displays onto buggies and allow companies to beam in messages wirelessly. The system works by allowing outfits to access a web-based profile, enter in a given message, and transmit the ad to participating stores. As an added bonus, the setup enables said companies to change up their messages on a whim and keeps us shoppers guessing as to what clever line is coming next. Now, who's down with hacking this thing to scroll through our favorite RSS feeds?

At this point we've seen so many variations on the "smart shopping cart" concept bubble up and fail we're pretty jaded, but the latest version, from Electronic Data Systems, seems like it almost maybe has a chance. Unlike previous concepts, the EDS model is built around the humble bar code: swiping items as you place them in your cart lets you keep a running tally of nutritional information, ethical sourcing, and environmental impact, letting you modify your purchasing decisions simply and quickly. Keeping it simple might be the winning strategy here, but we're not going to be convinced until the carts at our local can do more than just veer straight left.

If you're scouting out colleges to showcase your robot crafting skills, make sure the University of Florida is given some very strong consideration. Fresh off of a second straight victory at the Autonomous Underwater Vehicle Competition, the kids in Gainesville are flaunting another robotic creation that can make shopping a lot easier (and a lot safer). Gregory Garcia, a graduate student in mechanical engineering, developed a shopping cart that not only follows you around the store, but keeps a steady pace while cruising and throws on the brakes before clipping someone's heels. Garcia got the inspiration for the B.O.S.S. (Battery Operated Smart Servant) from his (presumably mischievous) little sister, who enjoyed ramming into his legs as a child while manning the buggy. A number of sensors aid the cart's maneuvering techniques, including a color sensor which allows the shopper to hold a piece of fabric behind them for the B.O.S.S. to keep track of -- it apparently accelerates and decelerates based on the speed and distance of the fabric ahead, and Garcia made quite certain that the shopping cart could stop on a dime in order to prevent those awkward heel injuries. While we're not sure how the cart would perform during the madness of holiday shopping, especially if it tried to follow every white (or green, or red) article of clothing around, but we're sure Gregory had a grand 'ole time finally showing that heel-biting cart who's boss.
