Scientists develop robotic worms to explore hard-to-reach places
Scottish scientists from the University of Glasgow have created robotic worms to explore hard-to-reach places. The machines will be used in prosthetics, rescue operations and industry, according to the Evening Standard .
It is noted that these robots are very flexible, they can stretch and thus increase the length of the body nine times. They are also able to move, taking into account the distance and position of the body in living organisms. With the help of such a sensation, earthworms navigate in space. The authors of the novelty suggest that this development could form the basis of a new generation of robots that can autonomously explore hard-to-reach areas and can penetrate where ordinary robots cannot. For example, it can be used to search for minerals, and also be used in rescue operations to search for survivors in the rubble.
According to Professor Ravinder Dahia, developments in flexible robots can form the basis of realistic prostheses. In addition, these machines can be adapted to carry heavy, irregularly shaped items.
It is worth saying that the robotic worms received built-in strain sensors. They are covered with “leather” made of elastic EcoFlex material with a special graphite paste. There are miniature permanent magnets at the two ends of the machine. They allow the artificial worm to move even on metal surfaces.
The sensors also help the robot “feel” the movements due to the electrical resistance of the graphite paste. This indicator changes when a bend occurs on the body. Then the sensor records the achievement of a predetermined value, after which the body straightens. This cycle allows the robot to move like an earthworm.
Earlier it was reported that a robot was created in Russia that will monitor oil platforms. Walking machines will help to make the inspection of technical structures regular and safe for people. Due to the universal components, they will be able to move effectively in both air and water environments.
