One oven-baked robot to go, please

Lots of people make their own robots, and in all sorts of ways, but have you ever heard of anyone baking one in an oven? Researchers at MIT have demonstrated how to create self-assembling bodies that fold together when baked, as well as showing how a similar technique can be used to generate electronic components to control them.Read More

Shape-changing implantable transistors grip living tissue

A multinational group of scientists has developed implantable shape-changing transistors that can grip nerves, blood vessels and tissues. According to the researchers, these soft electronic devices can change shape within the body, while still maintaining their electronic properties, allowing them to be used in a variety of applications and treatments.Read More

Sharks help scientists and themselves, by wearing cameras and swallowing sensors

Perhaps you've seen footage from National Geographic's "Crittercam," an underwater video camera that has been attached to animals such as sharks and whales. Well, scientists from the University of Hawaiʻi at Mānoa and the University of Tokyo have gone one better. Not only have they been putting cameras on sharks to see what they get up to, but they've also been slipping them ingestible sensors, to monitor their dietary habits. The data that they've gathered could help protect shark populations, and the overall health of the ocean. Read More

Moth takes the driver's seat in smell-tracking robot

In the future, we may have autonomous robots that follow scents to track down gas leaks, rescue disaster victims trapped in debris, or perform other duties. While the algorithms that drive such robots could perhaps just be made up from scratch, scientists from the University of Tokyo are instead looking to the insect world for inspiration. To that end, they recently created a two-wheeled robot that was successfully driven by female-seeking male silkmoths. Read More

BFS-Auto robot can read 250 pages per minute

Online book collections are becoming larger and more important each day. As more libraries are digitized, people are now able to read books on their tablets that once would have required traveling thousands of miles to even see. Scanning hundreds of thousands of books quickly without damaging them remains a challenge however, and it's a challenge which the BFS-Auto robot is well and truly up for.Read More

Augmented reality system could be a boon to dieters

You might think that your feeling of satiation when eating is due simply to your stomach filling up. According to the Hirose Tanikawa Group at the University of Tokyo, however, the visual perception of food also has something to do with it – the greater the amount of food that a person sees that they’re eating, the sooner they feel full. With that in mind, the team has created a prototype dieting system that uses augmented reality to trick people into thinking their food items are larger than they actually are.Read More

Camera system automatically keeps fast-moving subjects centered in the shot

A friend of mine who works in television once told me how he was shooting a hockey game, and was impressed with his uncanny ability to keep the puck centered in the shot at all times ... it turns out that the “puck” he was following was actually a speck of dirt on his viewfinder. A new system from the University of Tokyo, however, can automatically follow moving objects such as pucks with amazing accuracy.Read More

Japanese designers develop colloid bubbles as projection screens

If you ever thought of soap bubbles as small floating movie capsules, you were not alone in your observation. Researchers at the University of Tokyo have developed a system that uses such bubbles as kind of projection screen based on colloidal liquids. The bubbles are made of a thin film, and allow light to create a reflection on one section before passing through other sections. If the reflection can be controlled, then the bubble can be used as a display. Read More
