NASA: Robots Very Successful In Endeavour




Computer world- Shortly after the NASA space shuttle Endeavour undocked with the International Space Station this afternoon, officials called the mission's robotics work a huge success.

The shuttle and its seven-person crew spent 10 days, 23 hours and 39 minutes linked up with the space station to install the last of the Japanese laboratory there. And for those nearly 11 days at least one, if not two, robots were at work almost every day. Without them, the mission simply could not have been completed, according to Bill Jeffs, a NASA spokesman.

"This was a challenging mission from a robotics standpoint," Jeffs said in an interview with Computerworld today. "We used the robotic arm on the space station, the robotic arm on the space shuttle and the arm on the Japanese laboratory. In terms of robotics, it's been very challenging but very successful."

After the undocking, the Endeavour embarked on a so-called "fly-around" the space station which allows the astronauts still there to visually scan the outside of the shuttle for any problems with the critical heat shield. Once the inspection is completed, NASA pilot Doug Hurley is set to maneuver the shuttle away from the station and put it on a course to earth.

Endeavour is scheduled to land at 10:48 a.m. EDT on Friday at the Kennedy Space Center in Florida.

Before the mission, Holly Ridings, lead space station flight director for Endeavour, called it one of the most technical ever to be undertaken by NASA. With an ambitious schedule of five spacewalks, the astronauts onboard both the station and the shuttle used three robotic arms.

Ferrari's Innovative New V8—the 458 Italia


The Italia is the latest incarnation of the mid-rear engined Ferrari berlinetta and will be unveiled at the Frankfurt Motor Show in September. While it's true that every Ferrari is innovative by definition, it's equally true that in the course of the Prancing Horse's history, certain cars have marked a genuine departure from the current range. This is very much the case with the Ferrari 458 Italia, which is a massive leap forward from the company's previous mid-rear engined sports cars.

The new model is a synthesis of style, creative flair, passion and cutting-edge technology, characteristics for which Italy as a nation is well-known. For this reason Ferrari chose to add the name of its homeland to the traditional figure representing the displacement and number of cylinders.

The Ferrari 458 Italia is a completely new car from every point of view: engine, design, aerodynamics, handling, instrumentation and ergonomics, just to name a few.

A two-seater berlinetta, the Ferrari 458 Italia, as is now traditional for all Ferrari's road-going cars, benefits hugely from the company's Formula 1 experience. This is particularly evident in the speed and precision with which the car responds to driver inputs and in the attention focused on reducing internal friction in the engine for lower fuel consumption than the F430, despite the fact that both overall displacement and power have increased. However, Ferrari's track experience makes its presence felt in the 458 Italia not only in terms of pure technological transfer but also on a more emotional level, because of the strong emphasis on creating an almost symbiotic relationship between driver and car. The 458 Italia features an innovative driving environment with a new kind of steering wheel and dashboard that is the direct result of racing practice. Once again input from Michael Schumacher—who was involved from the very start of the 458 Italia project—played an invaluable part.

Nissan Unveils All-Electric Sedan Prototype

Nissan gave a glimpse of its plans to make an all-electric sedan that will go 100 miles on a charge and have a suite of online features to aid drivers.

The company on Monday showed off an electric car prototype, based on the Tiida mid-size sedan. It said that an all-electric production car with a unique design will be unveiled on August 2 at its Yokohama, Japan headquarters and go on sale in 2010 in Japan and the U.S.

The electric sedan will connect to Nissan's data centers to provide drivers with information and support, according to the carmaker.

The EV-IT system will display on a map how much driving range they have left and can calculate whether a car can make it to a pre-set destination. The system can point drivers to available charging stations within driving range.

The driver can also remotely view a battery's charge and turn on the air conditioner from a Web-connected computer or phone. Charging can be scheduled to take advantage of off-peak rates, too.

The car itself is built around Nissan's electric motor and a 24-kilowatt-hour battery pack which is placed under the car. With generative braking that charges the car during deceleration and braking, Nissan estimates that drivers can get 100 miles on a charge, although it notes that range depends on conditions and driving styles.

Although it lags in hybrids, Nissan has been one of the most aggressive in developing all-electric sedans. It is already testing the EV-02, which is based on the Nissan Cube chassis. It also has a partnership to work with Better Place, which provides consumers with charging points and access to battery-swapping stations in exchange for subscription plans.

Nissan has not announced prices, but a company representative told the Associated Press in Japan that the electric vehicle would be "competitive" with gasoline cars.

Because of the limitations on driving range and the high cost of batteries, other automakers including Toyota and General have said they expect consumers will favor gasoline-electric cars.

Along with Tesla Motors, start-ups Coda Automotive and Detroit Electric are making all-electric cars which they say will have enough range for daily driving for many people.

Female Robot Takes To The Catwalk

The latest hot model about to grace the catwalks of Japan made an appearance today. Fluttering her eyelids, HRP-4C as she is known, was unveiled by scientists as the most human-looking robot yet.

Rory Cellan-Jones has been taking a look.


Robotic Fish to Mimic Swimming



Researchers at the University of Bath are to build a robot to help understand how fish swim against the flow.

A consortium of five institutions have been awarded £1.5m to create the swimming robot trout.

The Ocean Technologies Lab at Bath will try to mimic the sense organ found in fish which allows them to detect the flow of water and react to it.

It is hoped the robot can be used in future for pollution control and monitoring the world's ecosystems.

It could also be used to study marine life near the seashore.

Complex controls

Dr William Megill, Lecturer in Biomimetics at the University of Bath said: "Currently, most aquatic robots can't manoeuvre very well in the shallow water near the shore because they just get smashed against the rocks by the force of the waves.

"However, even in a tsunami, fish manage to sense and swim against the current so that they stay in the water, rather than ending up on the beach.

"So this project is interesting on two levels - firstly we want to understand more about how the fish manages to react to changes in current, and secondly we want to create a robot that mimics this artificially."

The fish's complex nervous system will be emulated by computer software, developed by the University of Verona, which will allow the robot to interpret changes in flow outside the robot so it can adjust its swimming behaviour to compensate accordingly.

The FILOSE (Robotic FIsh LOcomotion and SEnsing) project is financed by the European Union.
