Abstract Pen-drawing is an intuitive, convenient, and creative fabrication method Protection Boot Bag for delivering emergent and adaptive design to real devices.To demonstrate the application of pen-drawing to robot construction, we developed pen-drawn Marangoni swimmers that perform complex programmed tasks using a simple and accessible manufacturing process.By simply drawing on substrates using ink-based Marangoni fuel, the swimmers demonstrate advanced robotic motions such as polygon and star-shaped trajectories, and navigate through maze.
The versatility of pen-drawing allows the integration of the swimmers with time-varying substrates, BERBERINE 500MG enabling multi-step motion tasks such as cargo delivery and return to the original place.We believe that our pen-based approach will significantly expand the potential applications of miniaturized swimming robots and provide new opportunities for simple robotic implementations.
