Dec. 12, 2012 — NTU scientists have invented a 'sense-ational' device, similar to a string of 'feelers' found on the bodies of the Blind Cave Fish, which enables the fish to sense their surrounding and so navigate easily.

Using a combination of water pressure and computer vision technology, the sensory device is able to give users a 3-D image of nearby objects and map its surroundings. The possible applications of this fish-inspired sensor are enormous. The sensor can...

Robots in the home: Will older adults roll out the welcome mat?

TechAndComputer (Oct. 25, 2012) — Robots have the potential to help older adults with daily activities that can become more challenging with age. But are people willing to use and accept the new technology? A study by the Georgia...

Brain waves reveal video game aptitude

TechAndComputer (Oct. 24, 2012) — Scientists report that they can predict who will improve most on an unfamiliar video game by looking at their brain waves.

They describe...

TechAndComputer (Oct. 23, 2012) — Teaching a robot a new trick is a challenge. You can't reward it with treats and it doesn't respond to approval or disappointment in your voice. For researchers in the biological sciences, however, the future training of robots has been made much easier thanks to a new program called...

Robots that perceive the world like humans

  • PDF
TechAndComputer (Oct. 18, 2012) — Perceive first, act afterwards.The architecture of most of today's robots is underpinned by this control strategy. The eSMCs project has set itself the aim of changing the paradigm and generating more dynamic computer models in which action is not a mere consequence of perception but an integral part of the perception process. It is about improving robot behaviour by means of perception models closer to those of humans. Philosophers at the...
