OK, it's restored my faith in humanity a little bit to know that we've invented a skateboarding balloon that walks on water.
The helium-filled body is just barely counteracted by the spindly legs and feet. The feet hide the actuating cables that bend the legs along a single degree of freedom, with very limited force. But it’s enough to put one foot in front of the other, or hop in place and a few other little tricks.
Changing its locomotion style (four legs instead of two, for instance, or giving a bit more power) could allow it to go faster, jump higher, even walk on water — and versions with these capabilities are all being pursued by the lab. Although in all cases there’s the risk of it blowing away.
