Under the cries of 60 000 rampaging soccer fans, the Brazilian goalkeeper Dida fix its target, conducts a long clearance and, as expected, Ronaldhino seizes the ball. In a performance that is both art, magic and the perfection of sporting gesture, the athlete starts in a ballet dribbles which stuns the defensive opponent. From the corner of the eye, he saw Ronaldo, demarcated, which darkens the goal. In a split second, his brain compiles data: the speed of his teammate, distance, trajectory and the tension he must give his password, the point of impact, and all this during that it is itself a full course. Contact! The ball leaves his foot and is in an arc just above a defender. Ronaldo jumped, and the head, redirect the pass perfect in the skylight. But Brazil! Considering the complexity of equations that describe such a sequence of the game, the computing power necessary to solve them instantly biomechanics and agility required to perform each of these gestures, one can not help thinking that only the human machine can accomplish such a prodigy.

This paper presents a control law for the tracking of a cyclic reference trajectory by an under actuated biped robot. The robot studied is a five-link planar robot. The degree of under actuation is one during the single support phase. The control law is defined in such a way that only the geometric evolution of the robot is controlled, not the temporal evolution. To achieve this objective, we consider a time-scaling control. For a given reference path, the temporal evolution during the geometric tracking is completely defined and can be analyzed through the study of the dynamic model. Continue reading
The group diversified Japanese electronics Hitachi introduced Wednesday a new robot designed to assist employees in offices and to replace the hostesses to make a green tea to visitors, through its faculties of communication and travel.
Called “Emiew 2”, this humanoid robot red wheels, 80 inches tall, is the descendant of Emiew, a first version designed by Hitachi in 2005.
“Emiew 2”, which includes 27 degrees of freedom (joints), is lighter than its predecessor (13 kg instead of 15 kg).
The robot assistance, designed to “cohabit with humans, is able to move independently at a speed of 6 km / h, even a human pressed. He can communicate by voice recognition and knows how to move within a company through a radar to bypass obstacles, and a map of places he could establish himself. “We will continue research and testing to ensure that in future robots can perform tasks in businesses, as visitors guide or carry out surveillance round,” said Hitachi.

In Japan, advances in robotics are at heart of new devices health adapted to an ageing society. It’s been a decade that the Japanese Honda automotive group had launched a research program to develop a device walking aid for the elderly and all those with mobility problems. Thanks to ASIMO, a humanoid robot research biped whose invention has required studying the works of man, this apparatus walking aid should soon be operational. It is still in the feasibility study but it is progressing quickly since it will now be tested in conjunction with doctors on patients during rehabilitation sessions to help them move efficiently and safely.

THEY MARCHENT, talk, recognize faces and become more sociable. Gone is the dream of science fiction: the robots have become reality and begin to integrate our daily lives. In factories, they perform technical tasks and at home, they want to keep us company or help us with household chores. Even if not all aspects of humanoids Hollywood. “The robot is in a situation comparable to that of early computers,” said Jerome Damelincourt, store manager Robopolis specializes in robotics. We have no idea yet what it will be in twenty years when the first computers arrived, it was not invented Word or Excel, or video games, much less the Internet. The role will have the robot in a few years remains a mystery. One can imagine that help children do their homework, we will replace it for the work boring, or that fits in everyday objects such as television or appliances. For now, we are at the stage where knowledge grow and multiply experiences. ” Continue reading
Honda has released a new version of its humanoid robot Asimo. This version is not fundamentally different from the previous one, but nevertheless provides significant improvements in the capabilities of the robot.
The best short (two times faster, or 6 km / h, but more importantly being able to follow a curve or slalom ant between plots). It is accompanied by new sensors, enabling it to better recognize its environment, or to hold a human hand in adapting its movements and displacements. It may finally seize objects and transport, maintaining his balance and adapting is also necessary force permanently. Continue reading
Through a rather simple equipment, a giant amoeba command the movements of a six-legged robot. Perspective: draw some manufacturing secrets that will one day be useful to robots.Quand the robot to six feet away from itself a source of light placed nearby, it does to any software or even a network Neural. The pilot is… a mold! More precisely Physique polycephalum, a strange organism in forests under the fusillades. This nice six-legged robot moves systematically light. However, no programme and no human would command him to do so.
This kind of yellowish giant amoeba, which is usually a few millimeters but may reach thirty centimeters, eats bacteria and small mushrooms. It has no legs and no body. All the cells were merged into a single plasmodia. Biologists rank among the myxomycetes, along with a few zoological curiosities hardly classifiable or plants or animals.
In short, this modest living being is nothing that can make it the ideal driver for a hexapod robot. Yet the role that made him played Klaus-Peter Zauner, Department of Electronics and Computer Science, University of Southampton (United Kingdom), in collaboration with a team from the University of Kobe, Japan. The driver, it’s him! This Schumacher Car hexapod is a kind of mold inform, moving like an amoeba. Continue reading
In the eagerly awaited World Exposition, which runs from March 25 to 25 September 2005 in Japan, the Japanese car manufacturer Toyota, will present its latest innovations in robotic its pavilion!
The site is located in Aichi an industrial area that is the stronghold of Toyota. Some therefore not hesitate to say that “Aichi 2005, Toyota Expo”. The theme on which this company has committed is: The dream, pleasure and excitement of mobility in the 21st century. The Toyota group will present at the opening of its pavilion and the inauguration of the International Exhibition 2005, a welcome spectacle with a show opening orchestrated by robots! They invite the visitor to discover the world of tomorrow.The main show will certainly be spectacular; visitors can admire the latest technological innovations robots vehicles unit and i-i-foot, a large screen to swivel 360 degrees and extraordinary scenic devices will be implemented so that visitors discover life, the nature and the future society represented on stage … Continue reading
A robotic head of bats capable of transmitting and detect ultrasound in the band of frequencies used by bats in the real world will give an important impetus to research in the field of echolocation. “Bat – Bot “, developed under the project CIRCE of the IST (Information Society Technologies) may also stir ears, technique often used by these animals to modulate the characteristics of the echo.
CIRCE developed the Bat-Bot to mimic more closely at the amazing qualities of echolocation in bats. “The sonar in water is an area controlled, but studies on a sonar air are much less advanced,” says dr. Herbert Parmesans, who heads the laboratory of active perception of the University of Antwerp and CIRCE coordinating the project. “Wherever roboticiens want to build an autonomous robot, they deal primarily the sonar, but they quickly encounter problems due to the nature too simplistic devices of commerce, and then spend the visual systems or laser. We hope that our research on the bat robotic systems will lead to more sophisticated sonar useful for robot navigation and other applications, “he says.
One of those potential applications could be identifying plants by echolocation. Continue reading
A new humanoid robot will serve as a guide loquace in the museum’s first automobile manufacturer worldwide, Japanese Toyota, inside his stronghold in central Japan.
Presented Monday, the robot to look feminine, with a height of 1.20 meters with a weight of 60 kilos, moves independently on wheels, avoiding obstacles.
Called “Robina”, it will guide visitors to the museum Automotive Group-Toyota City, near Nagoya (center).
According to its designer, “Robina” is capable of giving explanations to watching a person who recognizes the name on a badge. It can also keep a pen and sign autographs willingly, promised Toyota.A like his compatriot and Honda with its advanced technologies, Toyota has been actively engaged in the development of robotic technologies, convinced that the robots will in future play an important role in the aging Japanese society.
