Within the walls of Harvard University, they created the first robot that does not need power supplies, an electric motor, batteries and accumulators. The body parts of a soft robot named Octobot, which looks like an octopus, are driven by the released gas, which builds up inside a silicone body as a result of a chemical reaction. The body of the octobot is created on a 3D printer made of silicone with the addition of platinum particles. Inside the robot there is a central chamber filled with hydrogen peroxide. The liquid, passing through the channels-arteries of the octobot, reacts with platinum, as a result of which water and gaseous oxygen are formed. Gas, in turn, creating pressure in a series of pneumatic chambers, makes eight \Now, scientists are faced with the task of teaching their robo-pet to crawl and swim.
