Snake-Like Robot: Advancements in Microsurgery Technology

Scientists in Japan have developed a snake-like robot designed for microsurgery. Unlike conventional robots that use electric motors and face movement issues, this new robot uses electronic muscles made from polymer gel and gold, offering smoother movements. These gels can conduct electricity and change shape based on their environment. The team aims to create a smaller, wireless version of this technology.

What is the primary purpose of the snake-like robot developed by scientists in Japan?

How does the movement of the conventional robot differ from the new type of electronic muscle?

What materials are used to create the electronic muscles mentioned in the text?

Explain how polymer gels function in the context of the electronic muscle.

What challenges remain for the team working on the snake-like robot?
