Boston, Massachusetts - Researchers at Harvard have improved their soft-skeleton robot, and now can add colour to the pressurising fluid. The robot is made from silicone rubber. Low-pressure fluid is pumped into internal voids to modify the shape of the unit. With careful design of external and internal geometry, the unit can be made to walk.
In the latest paper in Science magazine, the research team says the fluids can be dyed. These coloured dyes show through the translucent structure to mimic colour-changing abilities of cephalopods, such as squid or cuttle fish
