Scientists have created a smart “self-healing” robot
What is the use of a rescue robot, if it just kind of danger adds tabs and can not function? What is the use of the robot, which was sent to the exploration of the area, but it can not cope with this task, as one of its parts broken and needs repair man? That’s right, no. Being an expensive milestone in the development of technologies, machines are not yet able to cope with such things as self-healing. However, robotics from the University of Pierre and Marie Curie created hexapod robot that is able to function even if one of its limbs is damaged, simply adapting (samostoyatelno!) to the situation.
Developed by scientists at the machine uses an algorithm called T-resilience (or T-recovery, where the prefix “T” means “substitutability”). How does it work?
The robot, endowed with all six fully functioning legs can move at a speed of 26 cm / s. But should he lose one of your limbs as speed drops to 8 cm / s. However, he begins to resemble a lame dog that can not cope with equilibrium. How to cope with such a situation? Rate the elegance of the solution! During the next 20 minutes robot diagnoses, as well as an entire group of simulations and tests, which are aimed at developing a new style of his gait, resulting in a maximum speed thereof is increased to 18 cm / s, which is quite sufficient for the robot got to the base, where it could be quickly repaired.
An important part of all this is that is responsible for conducting the tests the robot itself, not the scientists. He diagnoses the damaged parts of his robotic calf, he picks up the algorithms of “repair” and he also conducts tests for the correct simulation of future work in terms of their mechanical damage. Early studies of this question said that in this case the car will have to handle the huge amount of information to make the right decision, but the current team of the University Pierre and Marie Curie believes that the search for answers is much faster: by generating a number of possible alternative solutions to the problem based on information about the functioning of the “healthy” limb selected test solutions and its application in practice.
In alternative methods of treatment 25 in the robot leaves 20 minutes. During this time, a sensor mounted on the robot reads the defect information. Then, based on data on the work done (and still is) the way of his theoretical and practical performance, a new algorithm of movement, which allows the robot to adapt to the situation.
These developments simultaneously fascinated and at the same time frightening . And explain the reason for a second opinion, I think it is not worth it.
