Iván Hernández Dalas: Developing active and flexible microrobots
By C Huygelen Leiden researchers Professor Daniela Kraft and Mengshi Wei have created microscopic robots that move without sensors, software, or external control. Instead, their behaviour emerges entirely from their shape and the way they interact with their environment. This class of robots opens up entirely new possibilities for biomedical applications. Close-up of the microrobot. Inspired by nature Inspiration to build these robots came from nature. Kraft: “Animals like worms and snakes constantly adapt their shape as they move, which helps them to navigate their environments. Macroscopic robots similarly use flexibility for their function. However, until now, microrobots were either small and rigid, or large and flexible. We wondered if we could realize small and flexible microrobots in our lab.” Tiny, flexible, and surprisingly capable To find out, they designed a soft, chain-like structure made up of flexibly connected segments, and printed it using a 3D micro...
