Hydrogel-based microswimmer moving towards the target position with recognition of environmental changes

One of the major environmental issues facing humanity as society continues to rapidly develop is the destruction of the environment, especially by water pollution with organic, inorganic and human made material. Although efforts are being made to solve these problems, current measures are insufficient to deal with water pollution problems that have already occurred. Moreover, it is challenging to remove these pollutants directly from the aquatic environment. Research in underwater robotics is rapidly increasing and working toward solving these problems. Robots for solving and preventing water pollution should be able to recognize environmental changes in the aquatic environment and be able to detect large areas using programmable motion. It is also important to prevent secondary contamination by these robots. Underwater robots must be made from biocompatible materials and must be move using a fuel that is harmless to the environment. In this paper, we propose a biocompatible hydrogel based microswimmer to function as an underwater robot that can move toward a target position while simultaneously evaluating its environment and recognizing environmental changes.
