Researchers have created a new version of the robot-salamanders


Scientists often draw their inspiration from nature, when it comes to creating robots. Then spawn bots-fish, snakes, dogs , and even sea turtles. And indeed, scholars refer to the animal world for good reason, because if the challenge is building a robot that could move in a certain way, why not borrow underlying mechanisms in animals?

In the new work the “Salamandra robotica II”, which will be discussed below, scientists have tried to reproduce the movement, as it is easy to guess from the name, the salamanders. And now the robot can walk, crawl around as easily as they swim.

Salamanders are known by their structure perfectly adapted to life both on the water and on land. Legs allow them to walk on land and in the water moving through the movement of its body, like a fish. The design team of Lab robotic engineering at the Federal Polytechnic of Lausanne, Switzerland, wanted to know how one animal is able so quickly to adapt to the ways of movement and therefore created a robot-created salamander amphibian.





To do this, the research team has put together a mock skeleton and extremities salamanders, which subsequently could be used on the situation: If the robot is on the water, the movement he begins to use his feet, as if in water — the whole body. Walking robot is simply due to the fact that your legs start to rotate in a certain sequence. But the swimming is carried out through the use of nonlinear oscillators. Control of a robot-amphibian man is a laptop that wirelessly sends commands to the microcontroller installed in the salamander. In this way, you can change the direction and type of traffic, as well as speed. As a result of the construction of the first version of the robot in the year 2007, it taught to swim like a fish, crawl like a snake and walk as lizard.




The “Salamandra robotica II is the second version of this robot, more modern. In the new version of the robot are taught to swim faster, added removable legs and improved the microcontroller, which better handles simulation of nervous and muscular coordination and activity. Researchers hope that the update will work on water and land travel much easier and more natural, and it was for them an important part of this experiment.

The “Salamandra robotica II robot” are going to show the exhibition Innorobo 2013, which will be held from 19 to 21 March in Lyon, and from around the world congregate enthusiasts of robotics.
