In an engineering paper published online by the British magazine on January 23, German scientists reported a millimeter-scale magnetron software robot capable of performing different forms of motion. The robot is rectangular and can be switched between crawling, walking and swimming when transporting, which will have great potential in micro-engineering and health care.
Small robots that are currently available can reach many locations that humans cannot reach, but they are difficult to cope with complex terrain, resulting in limited applications. The new flexible device of software robot, although it has more mobility, is more difficult to make, and needs to be changed in the structure and control system. What is more difficult is to reduce the volume, especially Responsible for the motion control of the software robot.
Meit Sitti, a scientist at the Max Planck Institute for Intelligent Systems in Germany, has previously designed a viscous robot based on van der Waals forces on the surface of objects using viscous elastic rubber. This time, he collaborated with colleagues to develop a new magnetron-based silicone device that can only be switched between a variety of different motion modes, including roll and jump, swim and climb, depending on the terrain. set.
This magnetron software robot can also swim through liquids, move to solid unstructured surfaces without any physical intervention, and act as a "courier" - pick up tiny tiny "goods" and then Transport and store to a designated location.
Researchers say the magnetron software robots 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 health care field.
