Scientists have created a robot that can lift 1000 times its weight
Modern robots find a diversified range of applications from automating production to performing various useful things in our smart homes. The evolution of technology in recent years has led to the “Soft Robots”. In this category are compact machines that move with mechanisms mimicking the human body. This makes them more flexible and allows them to do much more. The big drawback is related to the limited power of the robots.
A team of scientists at MIT CSAIL & Harvard found an effective way to deal with this problem. Their joint project leads to the creation of a compact robot whose artificial muscles allow the prototype to lift a weight that exceeds 1,000 times its weight. Even more interesting is that to achieve this, scientists use only water and compressed air under pressure. Tests show that a muscle weighing 2.9 grams can lift up to 3 pounds.
This is an impressive achievement that can be applied to larger robots. The artificial muscles of the prototype are made of a plastic skeleton, placed in a hermetically sealed bag containing compressed air and water. Scientists have found that vacuum application provokes movement of muscles. In this case there is no need for external intervention and the whole mechanism works alone. Further tests are still underway with this interesting method of propulsion.
