Engineers at the University of California San Diego have developed a four-legged, soft robot that does not need any electronic devices to operate. The robot uses compressed air and a valve system to control its movements.
It works by controlling the air in the legs
Engineers built a valve system that acts as an oscillator and controls the order in which compressed air enters the air-powered muscles of the robot’s four arms. Each of the robot’s four legs has three degrees of freedom, working with three muscles. When pressure is applied to a cylindrical chamber, the limb bends in the opposite direction. This way, three sections of each limb provide the multi-axis bending required for walking.
The researchers paired the divisions of each leg diagonally together, simplifying the control problem. The robot is also equipped with simple mechanical sensors and small soft bubbles filled with liquid placed at the ends of the rods protruding from the body. When pressed against the bubbles, the liquid activates a valve that allows the robot to change direction.
The team believes their work is a step towards robots that do not contain fully autonomous electronics.
Can be used in places where the operation of electronic devices is not safe
Research team; He states that these cheap, simple and reliable systems can be used not only for gaming and entertainment purposes, but also in environments where electronic devices such as MRI machines or mining are not very safe to operate.
Michael T. Tolley, team lead of the study: “With our approach, you can make a very complex robotic brain. Our focus here was to build the simplest, air-powered nervous system needed to control walking.” made statements.
The team says that as a next step, they will try to improve the robot’s gait, making it easier to move across natural terrain and uneven surfaces.
