Most accurate robotic legs mimic human walking gait

  • PDF
TechAndComputer (July 6, 2012) — A group of US researchers has produced a robotic set of legs which they believe is the first to fully model walking in a biologically accurate manner.

The neural architecture, musculoskeletal architecture and sensory feedback pathways in humans have been simplified and built into the robot, giving it a remarkably human-like walking gait that can be viewed in this video -- http://www.youtube.com/watch?v=MnD7LqisBhM&feature=youtu.be.

The biological accuracy of this robot, which has been presented July 6, in IOP Publishing's Journal of Neural Engineering, has allowed the researchers to investigate the processes underlying walking in humans and may bolster theories of how babies learn...

Robot vision: Muscle-like action allows camera to mimic eye movement

  • PDF
TechAndComputer (July 5, 2012) — Using piezoelectric materials, researchers have replicated the muscle motion of the human eye to control camera systems in a way designed to improve the operation of robots. This new muscle-like action could help make robotic tools safer and more effective for MRI-guided surgery and robotic rehabilitation.

Key to the new control system is a piezoelectric cellular actuator that uses a novel biologically inspired technology that will allow a robot...

Artificial cerebellum than enables robotic human-like object handling developed

  • PDF
TechAndComputer (July 3, 2012) — University of Granada researchers have developed an artificial cerebellum (a biologically-inspired adaptive microcircuit) that controls a robotic arm with human-like precision. The cerebellum is the part of the human brain that controls the locomotor system and coordinates body movements.

To date, although robot designers have achieved very precise movements, such movements are performed at very high speed, require strong forces and are power...

Falling lizards use tail for mid-air twist, inspiring lizard-like 'RightingBot'

  • PDF
TechAndComputer (July 1, 2012) — Lizards, just like cats, have a knack for turning right side up and landing on their feet when they fall. But how do they do it? Unlike cats, which twist and bend their torsos to turn upright, lizards swing their large tails one way to rotate their body the other, according to a recent study that will be presented at the Society for Experimental Biology meeting on 29th June in Salzburg, Austria. A lizard-inspired robot, called 'RightingBot', replicates...

Musical robot companion enhances listener experience

  • PDF
TechAndComputer (June 26, 2012) — Wedding DJs everywhere should be worried about job security now that a new robot is on the scene.

Shimi, a musical companion developed by Georgia Tech's Center for Music Technology, recommends songs, dances to the beat and keeps the music pumping based on listener feedback. The smartphone-enabled, one-foot-tall robot is billed as an interactive "musical buddy."

"Shimi is designed to change the way that people enjoy and think about their...
