I can see the military probably already making good use of this sort of technology in for instance surveillance operations to crawl, hide and listen extra. personally I think they would make great little cheep mine sweepers or terrain mappers (:

I was wondering that too myself. If I was going to do it ivwould most likely end up with some sort of gas filled displacement chamber squashed with a geared down servo or something similar (so as not to take compressed air down that could potentially run out -although the small canisters for fast inflation of bicycle tyres would be good for that)
I suppose that hard bit would be making the system small enough. These things are not that large. Light waight though considering all the servos and power source. I’m wondering how long that lasts when it has to operate the control gear and four servos and any potential extras? Maybe solar for land based and some sort of fuel cell charging system for water based applications maybe a hood direction to go in?
Would love to see these things deployed in mass from some sort of arial vehicle (:

nice,

although this would give me the creeps if i saw it coming out of the water towards me.

i didn’t see it ‘hovering’ in the video, it either sank or floated (ok, it kind of sat up a bit off the bottom). i guess its harder to get it to actually stay stationary somewhere in between.

how are they powered, and what’s the battery life on those?

“and here we see film of the first primitive water robots climbing onto land.”

I hope it doesn’t come out of the water to head towards some mean domestic geese. Because it’s goose might be cooked. Wild geese may take off domestic geese stand their ground. Wouldn’t be great if they could mate, reproduce, free bots. Well on second thought, that could be the stuff a horror movie could be based on.
