CMU’s Snackbot is a roving wheeled ‘bot who’s primary purpose is to roam the halls of the University’s buildings, delivering tasty treast to students and faculty. Snackbot not only drives around bringing snacks, he also brings plenty of goodwill, with a pleasant-sounding voice communication system and calm demeanor unlikely to be rattled by even the most demanding snack customer. He features a sophisticated “multi-sensor fusion algorithms” which let him understand where he’s going, navigate through crowds, and can autonomously learn new objects.

My only complaint is that all that he seems to be delivering in the video clip above is granola bars and souvenirs. What kind of snacks are those? Where are my Ding Dongs, Ring Dings, Big Wheels and King Dons? Even Snackbot’s early prototype delivered M&Ms, Twix and Oreos…

While Snackbot was designed for a nobler cause – studying human-robot interactions, bringing snacks to my office each day would be plenty reason for me to invest research dollars – as long as there are creme-filled snack cakes, that is.

Carnegie Mellon University grad student Chris Harrison and CS professor Scott Hudson have developed a tactile interface that lets you actually feel and press virtual buttons that emerge from a touchscreen. The prototype uses a combination of rear-projected images, infrared sensors and a layer of flexible latex from which the buttons rise and fall.

A custom cut acrylic layer behind the buttons gives them their shapes, and air is pumped into and out of the chambers behind the buttons to automatically change the button states as the images change.

The system is capable of detecting more than one simultaneous press using readily available infrared multi-touch technology, and can even figure out how hard you’re pressing on the buttons by monitoring air pressure. To see the system in action, check out this video clip:

While the prototype version is clearly not practical or cost-effective for real-world use, the overall concept is really cool, and I’d love to see them figure out a way to miniaturize the technology so it could be crammed into a mobile device some day.
