New Scientist Tech – Breaking News – Speedy robot legs it to break record

A two-legged robot that walks at record-breaking speed has been developed by researchers from Germany and Scotland.

“RunBot” is the fastest robot on two legs – for its size. At 30 centimetres high, it can walk at a speedy 3.5 leg-lengths per second. This beats the previous record holder – MIT’s “Spring Flamingo” – which is four times as tall but manages just 1.4 leg-lengths per second.

The robot is controlled by a simple program that mimics the way neurons control reflexes in humans and other animals. Unlike most other two-legged robots, RunBot has few sensors and can detect just two things – when a foot touches the ground, and when a leg swings forward.

“We wanted to show that a very simple system with a simple neuronal controller could walk in a natural manner – and fast,” says Florentin Wörgötter, from the University of Göttingen in Germany, who developed RunBot along with researchers at the University of Glasgow and the University of Stirling, both in Scotland.

Two mpeg videos show RunBot walking at a steady speed and gradually learning to walk more rapidly.

HAL: “Robot Suit HAL (Hybrid Assistive Limb)”

Univ. of Tsukuba

We developed the exo-skeleton type power assist system to realize the walking aid for the gait disorder person.

At the present time, HAL-3 is state of the art power assist system in the world.

Some sensors such as angle sensors, myoelectrical sensors, floor sensors etc. are adopted in order to obtain the condition of the HAL and the operator.

All of the motordrivers, measurement system, computer, wireless LAN, and power supply are built in the backpack.

Using the battery attached on the waist, HAL works as the complete wearable system.


Japan unveils “robot suit” that enhances human power – Yahoo! News

TOKYO (AFP) – Japan has taken a step into the science-fiction world with the release of a ‘robot suit’ that can help workers lift heavy loads or assist people with disabilities climb stairs.

‘Humans may be able to mutate into supermen in the near future,’ said Yoshiyuki Sankai, professor and engineer at Tsukuba University who led the project.

The 15-kilogram (33-pound) battery-powered suit, code-named HAL-5, detects muscle movements through electrical-signal flows on the skin surface and then amplifies them.

It can also move on its own accord, enabling it to help elderly or handicapped people walk, developers said.

The prototype suit will be displayed at the World Exposition that is currently taking place in Aichi prefecture, central Japan.
