Researchers at Northwestern University have developed an underwater soft robot that is similar to sea creatures. The robot is 90 percent water and has the ability to transport cargo, climb hills and release a particle by ‘break-dancing’. The centimeter-sized robot looks like a four-legged octopus and would be most useful in an underwater environment.
