Synthetic muscles printed on a 3D printer are three times stronger than human
Humanoid robots have become even more perfect, thanks to artificial muscles, which will allow them to lift the cargo 1000 times its own weight.
New artificial muscles were developed by a team of engineers from Columbia University, headed by Professor Hod Lipson. They are created by the method of 3D printing and have a unique plasticity and mobility. Muscles can produce pushing movements, with their help you can pull, bend, twist, and also lift weights.
The ability to lift heavy loads is provided by a combination of a powerful electric drive and silicone rubber with a low density, in which microbubbles of ethanol are distributed. 3D printing gives the muscles the right shape, and they are powered by a power source with a voltage of only 8 volts.
According to Professor Lipson, unlike “hard” robots androids with soft muscles can more naturally reproduce grasping movements and perform various subtle manipulations – for example, to provide medical assistance or pick up soft objects.
During the experiments, the muscles were able to stretch up to 900% of their original size, due to heating to 80 ° C. Now in the plans of developers to connect to the control of muscles artificial intelligence, which will radically improve the accuracy of the performed movements and the speed of response of the system.
