According to a recent report on the Spanish “Herald” website, the Spanish scientific research team has developed a robot that can swim and self-train based on muscle cells.This one uses muscle cells and3D printingThe small soft swimming robot made by the machine is the latest result of successful research and development by a group of researchers from the Catalan Institute of Bioengineering.

According to the report, the field of robotics has a huge source of inspiration in biological systems. By imitating and combining the complex behaviors or characteristics formed after thousands of years of evolution, it can be transformed into the improvement and perfection of technical equipment. Imagine that a robot’s body can heal itself when it is broken, just like human skin. Imagine again, what if it is not a robot that has this function, but a prosthesis for the disabled?
The biorobot developed by the Catalan Institute of Bioengineering team looks more like a living creature than a robot. These soft objects, which are only more than 1 cm long, consist of two different parts.Like small worms, they can contract and stretch, thanks to the organic materials used inside and made of3D printingThe obtained spring-like structure-a soft polymer called PDMS. In addition, a set of muscle fiber structure can produce synchronized movement in the contraction of this polymer.
“Muscle cells contract, compress the spring, and then the spring stretches again. In this way, they can train themselves to increase their strength.” The head of the research and development team, Professor Samuel of the Catalan Institute of Bioengineering Sanchez explained.
The report pointed out that it is for this reason that the biohybrid robot developed by the team moves nearly 800 times faster than other robots that also use muscle fibers. Recently, an article published in the journal “Science Robotics” introduced this project. The researchers described in the article how they studied different skeletal systems.According to Sanchez, after 4 years of hard work, they finally found the opening3D printingThe “key” to the door of bionic robots, and successfully made them mobile.
Maria Gikes, the first author of the research paper, said that the team worked hard to find the correct movement mechanism by giving play to the shape and material flexibility of the internal components. Jikes also said: “The key is to achieve continuous movement of the robot. If it is very stiff, it can only be contracted once, and will not move continuously.”
