New artificial muscle comes out: overcome the last level of making realistic robot

According to foreign media, "Fortune" magazine recently reported that the existing robot is still unable to complete the fine action, such as picking up a soft object without causing any damage, therefore, Columbia University School of Engineering and Applied Science researchers to develop a new type Artificial muscle, to bring huge improvements to robot applications.

Artificial muscle

This artificial muscle is made of 3D printed material that is internally filled with a silica gel matrix containing ethanol bubbles. This material has a strain energy density of 15 times that of a natural muscle and can lift objects that weigh 1000 times their own weight. In the past, researchers often used pneumatic or hydraulic expansion to adjust traction pressure, but this required the installation of components such as compressors outside the material.

These component devices take up a lot of space and can not make robot components that are small and stand-alone. Therefore, the newly developed synthetic muscle internal installation of ultra-thin resistance wire, through the electric drive to achieve low energy consumption of simple equipment, pull-up and contraction movement.

Hudi Lipson, a professor of mechanical engineering and head of the research team, told the media that the scientific community has made great strides in the study of the concept of robotics, but the level of robot torso manufacturing has never stopped. Solving this dilemma is as hard as getting creatures to evolve. Mechanical parts can be remodeled or modified in thousands of ways, and synthetic muscle research and development is designed to overcome the last hurdles to make realistic robots.

In recent years, the ability of rigid robots to move and execute more and more powerful, all kinds of complex movements can be completed quickly, but lack of flexibility. Synthetic muscle brings a whole new feel of softness that not only achieves the level of dexterity that current grappling techniques can not achieve, but also helps to create special soft robots.

The researchers revealed that robots made with new technology can help humans in fine workmanship, such as making the next generation of integrated prostheses, and even allowing users to control their prosthetic muscles through terminals such as cell phones. The next step in the new study is to replace the resistance wire used in synthetic muscle to shorten the response time of muscle parts and increase their life. In the future, scientists plan to use Artificial Intelligence AI to control the movement of materials to develop more realistic humanoid robots.

Aluminum High-strength Thin Sheet

Aluminum High-strength Thin Sheet is one type of Aluminum Sheet which has high strength but with the thin thickness.It is good in performance condition which requires high strength.Regularly when the thickness of the aluminum is reduced,the strength of the same is also reduced.The main difference is from a special heat treatment process which enables the thin aluminum sheet with a high strength.So in the clients end,it is possible to use less aluminum material to produce the same product with same strength.The technology innovation is good for reducing the usage of the energy which also reduced the carbon oxidation.We hope to bring better future for our next generation.
