In an engineering paper published online on the 23rd in the British "Nature" magazine, German scientists reported a millimeter-scale magnetron robot capable of performing different forms of motion. The robot is rectangular and can be switched between crawling, walking, and traveling in three shipments. It will have great potential in microengineering and health care.
Currently available small robots can reach many locations that humans cannot reach, but it is difficult to deal with complex terrain, resulting in limited application. The flexible robot, a new type of flexible device, although it has more mobility, it is more difficult to make, and it needs to make corresponding changes in the structure and control system, and even more difficult is to reduce the volume of them, especially The part responsible for the motion control of the software robot.
Chemin Siti, a scientist at the Max Planck Institute for Intelligent Systems in Germany, previously used viscous elastomeric rubber to design a viscous robot based on van der Waals's force absorbed on the surface of the object. This time, he collaborated with his colleagues to develop a new magnetron silicone device that only has a millimeter scale, but can switch between a variety of different forms of motion, including rolling and jumping, swimming and climbing, depending on the terrain. set.
This magnetron robot can also swim through liquids, move to a solid unstructured surface without any physical intervention, and can act as a "courier" - picking up extremely tiny "goods" and then Transport, store to a designated location.
Researchers say that this kind of magnetron robot will play a huge role in the process of preparing microbial cells themselves or their metabolites through modern engineering techniques, as well as targeted drug delivery or minimally invasive surgery in the medical and health field.
