Robot evaluates tissue layers with nanometer precision

imagesThe robot is capable of displaying NanoZoomer with an extremely high resolution tissue samples at various levels in order to help the understanding of cancer. This allows detailed assessment of the effect produced by cancer treatments on cells and tissues. This development is the result of cooperation of the institute of pathology and medical and biometric information from the University of Heidelberg and the Japanese company Hamamatsu Photonics.

Dr. Niels Grabe of the Institute of Biometry and Medical Informatics and research director of TIGA notes that in the future robots will be able to determine in a fully automatic changes in cells and tissues.

Evolutionary Robotics (Evolutionary Robotics)

225362-286784This approach applies the knowledge gained from the natural sciences (biology and ethology) and Artificial Life (neural networks, evolutionary techniques and dynamical systems) on real robots, to develop their own skills in close interaction with the environment and without human intervention.
With a fixed design, it is difficult to have a robot suits (self-organized) to a dynamic environment that evolves through-often-chaotic changes. Hence, the evolutionary robotics can provide an adequate solution to this problem because the machine can automatically acquire new behaviors depending on the dynamic situations that occur in the environment where it is located.

Through the use of evolutionary techniques (genetic algorithms, genetic programming and evolutionary strategy), you may decide to evolve the control system or certain features of the robot body (morphology, sensors, actuators, etc.). Or co-evolve both. Similarly, you may decide to evolve physically the hardware (electronic circuits) or software (program or control rules). However, little is done on evolvable hardware [Fernández León, 2004] and usually what is done is to move first driver in a computer simulation, and only then, are transferred to real robots. The robot controller typically consists of artificial neural networks, and evolution is to change the weights of the connections of the network.

Currently, the main drawback is its slow evolutionary control convergence speed and the considerable amount of time that must pass to complete the evolutionary process on a real robot [Pratiharas, 2003]. It is not appropriate for solving problems of increasing complexity [Fernández León, 2004].
Robotics Biomimetics, Biologically Inspired Robotics Biorrobótica or
This approach is concerned with designing robots that function like biological systems, hence they are based on the natural sciences (biology, zoology and ethology) and robotics. Given that biological systems perform many complex processing tasks with maximum efficiency, provide a good reference for implementing artificial systems that perform tasks that living things do naturally (interpretation of sensory information, learning, movement, coordination, and so on. ) [Ros, et al, 2002]. Although it is possible to obtain different degrees of “biologically inspired” (from a vague resemblance to an acceptable reply), the ultimate goal is to make machines and systems increasingly similar to the original [Dario, 2005].

The advantage of building bio-robots is that, as is possible to study all their internal processes, they can be contrasted with the different organs of the animal from which it is based. Currently, scientists develop locusts, flies, dogs, fish, snakes and roaches robotics, in order to emulate a greater or more behavior-robust, flexible and adaptable animals. However, few machines resemble their natural counterparts.

Replicate biology is not easy and could be some time before they can produce biomimetic robots that are truly useful. Another problem, perhaps the most-is that, although well aware of the different processes of many of these living beings, there is a huge difference with their human counterparts. Indeed, the manner in which man perceives and acts is extremely more complex than a lobster does, to give an example.

D-bot by Roger

imagesThis robot is built using a 6-wheel motorized toy called the BOSS (Battery Operated Spin System) which was available at toy stores a few years ago for about $120. The unit included wheels, gear motors, batteries and charger. The plastic stuff was tossed and a wooden base was attached and multiple decks made from sheets of aluminum. The power electronics including the batteries and motor drivers are on the bottom deck, the computer is on the second deck and the sensors are on the top deck. The computer is a standard PC/XT motherboard which controls the 2 DC motors using the parallel printer port. Software resides on a 3.5″ floppy and automatically boots the robot program which was written in Quick-Basic V4.5. The software has the ability to read a joystick and record motions then play back the motions. This teach-and-repeat technique works well for short robot competitions where the task is well defined. Overall cost was about $450. Email questions to roger@robotics.com

IA: a robot becomes more intelligent by asking for help

lecturerobotTo advance artificial intelligence, robots are simply asking for help to humans. That is the idea advanced by Willow Garage, a company specializing in robotics based in Palo Alto, California. According to the company, asking for help is the second nature of human beings and this behavior could help solve one of the thorniest problems in artificial intelligence. Continue reading

Brazil: train robots to compete in the football World Cup in Austria

eurobot_bresilSAO PAULO (Brazil) (AFP) – Seven students fanatical Brazilian electronics work on the ground to improve the offensive and defensive strategies of their robots compete in the “Robocup 2009” which begins Monday in Austria. They run, dribble and mark: these robots play soccer through the development of artificial intelligence is not only used in major laboratories world but also in fairs Ignaciana University Educational Foundation (EIF), Sao Bernardo dos Campos, in the southern state of Sao Paulo.

They interact on a synthetic grass with a golf ball, microchip and high technology to prepare their team of six robots who will travel Saturday to Graz (Austria) to compete in robotics competition “Robocup football from June 29 to July 5. More than 400 teams from forty countries participate in this sort of World Cup for robots. Brazil will be represented by the team of the FEI and the Federal University of Rio Grande do Sul.

The FEI team consists of six robots, seven students in computer science and electrical engineering and two teachers, but only five students will travel with the “players” because of high costs of travel.
Young people work tirelessly to refine devices robots. Mechanics has been improved in the last minute, as Eduardo Garcia, 28, and Gabriel Francischini, 20, are they the final touches, screwdriver in hand.

The system allows the robots to play soccer alone is simple, according to these experts: high-precision cameras filming from above the football field and send the information to a computer. The computer program analyzes the situation, defines what will be happening next and sends the signal via radio to the robot receives the order and executes it.

Each “player”, 15 cm high and 30 cm in diameter has sensors for “foot” that helps to know if he has the ball.Five robots are the team owner and a sixth will remain on the bench in case of “injury” of a player during the match two halves of ten minutes each. Each robot has position: striker, defender, midfielder or goalkeeper. The program can calculate the force of the shot on goal or pass and the speed at which the players move, “says José Angelo Gurzoni, 28 years.

The FEI team is three time champion Brazil in the category “very small” (very small) but play the Robocup in that of “small size” (small).
For developing, it took many hours without sleep, money and collaboration with foreign universities. Students work with a computer program and the mechanisms of American Studies centers have shared with them.

Engines precision robots have been purchased in Austria, plates and electronic parts are Brazilian and high definition cameras have been ordered from a factory in Germany. All investments have come from the coffers of the university. Of the 25 teams competing in the category “small size”, Brazil in particular feared five, including Thailand, defending champion. So far “no Brazilian team has won the Match” for the Robocup says Gurzoni. But “the idea of this type of competition is primarily to generate knowledge and share with other universities,” says he.
