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 issue with conventional robots used in microsurgery?

• Their movements can become jerky when encountering resistance.

• They require a lot of energy to operate.

• They are too expensive to produce.

• They are too large to be used inside the human body.

What material is used to coat the polymer gel in the new electronic muscles?

• Gold

• Copper

• Silver

• Aluminum

How do polymer gels in electronic muscles respond to their environment?

• They change color.

• They swell and shrink.

• They emit light.

• They become magnetic.

What happens to the electronic muscle when it is wet and an electric charge is applied?

• It changes color.

• It disintegrates.

• It moves smoothly to one side.

• It becomes rigid.

What is the team currently working on to improve the electronic muscle technology?

• A larger model with more power.

• A model that can change colors.

• A version that can operate in extreme temperatures.

• A smaller, wireless version.
