Lemon Peel-Like Robot Made Up of 90% Water Only Needs Light to Work, Can Walk and Dance Like Humans

This new aquatic robot is made up of 90% water! What's great about it is that it only needs magnets and light to work.

These include walking, dancing, and carrying small objects. The robots take in and expel water through their soft components and can work when light and magnetic fields are present in the surrounding.

They can do these because of their precise molecular design. When light hits the robot's molecular structure, the molecules would expel water, causing the machine's legs to harden, just like how human muscle works. You can say that these robots can flex.

What makes this water-based robot different?

Tiny robots usually crawl like snails or fly like tiny insects. However, this one is different since it can walk like humans. The scientists also said that the new aquatic bots can cover one human step in one second, just like a human's casual saunter.

"By combining walking and steering motions together, we can program specific sequences of magnetic fields, which remotely operate the robot and direct it to follow paths on flat or inclined surfaces," said Monica Olvera de la Cruz, the project's co-lead author via New Atlas.

"This programmable feature allows us to direct the robot through narrow passages with complex routes," she added.

With all the robot's promising features, there's a high chance that it'll be used in medical purposes. If the researchers and developers can make it smaller, it can deliver drugs into the human body without the need of operations. Who knows what can these tiny aquatic robots can do once they are fully launched.
