Although robotic technology has made great advances for nearly seven decades, But all the machines Including the robot’s legs, they all rely on motors. It’s a technology that’s more than 200 years old. Researchers from ETH Zurich and the Max Planck Institute for Intelligent Systems (MPI-IS) have developed the muscle. -Robot drive -Challenge this norm by developing procedures characterized by excellent energy efficiency and adaptability.
A team led by Robert Katzman from ETH Zurich and Christoph Keplinger from MPI-IS, as well as PhD students Thomas Buchner and Toshihiko Fukushima, have published their findings on a force-treated musculoskeletal robot leg. Inspiration from animals in the journal Nature Communications.
The new legs differ from traditional robot legs in that they have extensor and flexor muscles that are moved by Electro hydraulic servo valve Market, or HASELs. Actuators resembling plastic bags filled with oil contract when Voltage This results in the bag becoming lighter and the leg moving. When a resisting muscle contracts, it expands, mimicking natural muscle movement in living things.
The researchers compared the energy efficiency of the robot’s leg with that of a conventional motorized leg. And it was found that muscle-powered legs used significantly less energy. Especially when the legs are bent. Therefore must rely on a heat management system.
The leg’s muscle-powered jumping ability is a result of its ability to lift explosively. In addition, the foot has a high degree of adaptability. This is important for soft robots. Because it can be adapted to different areas. flexibly
Inventors and researchers have been developing robots for nearly 70 years. All the machines they have created to date have been For factories or anywhere else, they have one thing in common: they are driven by a motor. This is technology that is 200 years old. Even robots that can walk have their arms and legs powered by motors. They are not muscular like humans and animals. This partly explains why they lack the agility and adaptability of living things. The new muscle-powered robotic legs are not only more energy efficient than traditional feet. But can also jump high and run quickly. Including detecting and responding to obstacles. It doesn’t all have to be complicated. The new leg sensor was developed by researchers at ETH Zurich and the Max Planck Institute for Intelligent Systems (MPI-IS) in a research collaboration called the Max Planck ETH Center for Learning. Systems also known as CLS The CLS team is led by Robert Katzman at ETH Zurich and Christoph Keplinger at MPI-IS. Their PhD students, Thomas Buchner and Toshihiko Fukushima, are co-first authors of the team’s publication on force-gated musculoskeletal robot legs. Animal inspiration in Nature Communications The same is true in humans and animals. Extensors and flexors ensure that the robot legs enter. can in both directions These electro-hydraulic actuators, which the researchers call HASELs, are attached to the tendon by tendons. The actuator is a plastic bag filled with oil. The same is used to make ice cubes. One half of each vial is coated on both sides with black electrodes made of conductive material. Buchner explains that as soon as we apply voltage to the electrodes, The two electrodes are attracted to each other due to static electricity. And when I rub a balloon on my head My hair got stuck in a balloon because.
