China News Service, Beijing, September 25 (Reporter Sun Zifa) Springer Nature’s open access academic journal "Communications-Materials" recently published a technology research and development paper saying that researchers have successfully developed a new type of magnetic Drive high-speed soft robots that can walk, swim, float and catch live flies.
The paper pointed out that for the creatures in nature, high-speed action is essential for hunting, escape, and flying. This is also useful for soft robots, because it allows the robot to capture fast-moving objects and quickly respond to the surrounding dynamic environment. Response, but it is very challenging to replicate this high-speed action on a robot.
Electric motors can mimic this behavior on "hard" robots, but some cheap and simple robotic systems based on materials such as plastic or rubber are used.
The corresponding author of the paper, Denys Makarov of the Rosendorf Research Center in Dresden, Germany, and his colleagues, demonstrated the design principles, materials and production of a magnetically driven high-speed soft robot in the paper Process, they embedded tiny magnets in the robot body, which can quickly respond to the magnetic field, so that the robot can move according to their specific shape.
According to reports, this design has achieved the highest specific energy density reported so far for a soft robot, which is critical for high-speed driving under low magnetic fields.
The author of the paper said that in the future, these robots may be used in biological tissue engineering, as a component of a larger robot system, and can also be used to study the biomechanical response of high-speed moving organisms.
