Soft things are cute. Soft things are also fun to touch. And that's part of the reason why you should care about this soft octopus robot.
According to a study in the journal Nature, soft robots could even make human interactions with robots safer than with more conventional "rigid" robots.
The autonomous robot is "the first self-contained robot made exclusively of soft, flexible parts."
It's powered by gas. Harvard University explains it this way: "A reaction inside the bot transforms a small amount of liquid fuel (hydrogen peroxide) into a large amount of gas, which flows into the octobot’s arms and inflates them like a balloon."
