This 3D-printable robot can walk around without any electronics, and it kind of looks like a deep-sea creature

3D printing is a great way to create robot shells, but you usually need an extra component to actually get them moving. The easy and more obvious answer is to wire it up with electronics to power its legs, but what if that was a no-go? What if you had to create a robot that didn't use electricity whatsoever to move? If it sounds impossible, then do I have the project for you, as this 3D-printable robot uses the power of air to get around.
