A robot that consists entirely of soft materials has been developed by researchers at the Harvard University. Its the first completely soft-bodied robot, dubbed the “Octobot.” Earlier when soft robots were manufactured, they still needed to be linked to, or contain, something ‘hard’ to function. But the team of scientists have thus managed to get around this.
The researchers have constructed a small octopus-shaped robot that is able to lift and lower its eight arms, four at a time. It is basically made of a rubber-based material. They then put in a lot of three-dimensional channels in the rubber. And blow air into one of the channels, which expands the structure so that it moves, according to scientist Max Hamedi who has worked with the US research team that designed the robot. In this case is not normal air, but gas formed from chemical reactions with hydrogen peroxide.
