Earthworms creep along the ground by alternately squeezing and stretching muscles along the length of their bodies, inching forward with each wave of contractions. Snails and sea cucumbers also use this mechanism, called peristalsis, to get around, and our own gastrointestinal tracts operate by a similar action, squeezing muscles along the esophagus to push food to the stomach.

For decades, academic and industry researchers have been working on control algorithms for autonomous helicopters — robotic helicopters that pilot themselves, rather than requiring remote human guidance. Dozens of research teams have competed in a series of autonomous-helicopter challenges posed by the Association for Unmanned Vehicle Systems International (AUVSI); progress has been so rapid that the last two challenges have involved indoor navigation without the use of GPS.

Kinect technique lets your body control virtual avatars of things around your house.
Ever wanted to make your bookshelf shake its booty just by shaking your own? Graphics gurus at Microsoft Research have a new system that will let you do just that — possess other inanimate objects around your house or even make images of other people move. The KinÊtre project starts with a KinectFusion scan of an… read more

A team of seven undergraduate students at Northeastern University designed and built a “nearly indestructible” robot that can enter rugged territory and create a theoretically infinite WiFi networks as it goes.
The team faced three problems: they needed a robot that could travel over rough terrain or rubble; the WiFi network had to be robust, cheap and easy to deploy; and they needed a way to control the robot… read more

PopFab is a 3D printer that fits inside a briefcase. At its heart is a computer-controlled motion platform and a means of attaching various toolheads. These enable PopFab to make objects from a digital plan in a variety of ways: current capabilities include 3D printing, milling, vinyl cutting, and drawing — with more on the way. PopFab has traveled the world as a carry-on item of luggage.

Bonnie Bassler discovered that bacteria “talk” to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry — and our understanding of ourselves.
Bonnie Bassler studies how bacteria can communicate with one another, through chemical signals, to act as a unit. Her work could pave the way for new, more potent medicine.

Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look “around” corners or see inside the body without X-rays.
Photography is about creating images by recording light. Ramesh Raskar and his team members have invented a camera… read more
