How does it handle lack or inertia? To float it must be very lightweight, so every time the kids hit it it will go and colide with the walls.

PS: If you have a small kid, helium balloon are a super nice present. Wrap them in paper for an additional surprise. Remember to give it to the children in a closed room.

Helium filled eh? I don't think this is a good idea.

It does look cute. I could imagine something like this being at children's museum or something.

Okay looks cool, but what can this robot actually do? I get the concept and the mechanics, but it’s not obvious what the practical capabilities are. Is it meant as a research platform for soft robotics, a demo of compliant movement, or does it have any specific real-world tasks in mind like inspection, underwater sensing, or manipulation? I’m curious what the intended application is beyond the technical novelty.
