Robot as caterpillar
Nature provides engineers an inexhaustible source of inspiration. The problem is that what is common in nature and obvious, sometimes very hard to play . Once you succeed, the results can be impressive.
A good example is the achievement of Polish engineers from the Department of Physics, University of Warsaw, which has managed to build an amazing machine. Constructed their robot resembles a small caterpillar. It has an oblong shape and body consisting of several segments. presents itself inconspicuously , but its features amazed the world.
Polish robot with no rigid parts
Robot there are no rigid elements . There is also no joints or joints. Although it is able to controllably bend, and move in the desired direction to squeeze through the various slots move over uneven, and to move a weight of up to six times more than the weight of the robot.
machine with a liquid-crystal elastomer
the secret of its features is the material from which it was built. The designers used the robot in fact one of the so-called. Smart materials, or liquid crystal elastomer (LCP). Its unique feature is that the light beam of the laser can reversibly change shape. Changing it in the right places can make a device moves like a caterpillar , turns and pushes before him various objects, including up to six times heavier than himself.
The result is a machine devoid of mechanical parts, which can be controlled remotely via laser beam, which is both a source of supply . The creators of this equipment are hoping that after refining can be – using the tested solution – to build not only crawling machines, but also robots floating above and below the water’s surface.
