Yikes!
But it doesn’t have a beer cooler.
(Jet powered beer cooler.)
From the video, it doesn’t operate anything like my design.
It appears the foot controls are like motorcycle gear-shift levers, left toe for left side advance, right heel for right side retreat, gives you a turn.
It also seemed to need a lot of hydraulic pressure. I think that’s why he stopped and revved the engine for a while.
Still, the articulation of the legs was interesting, and functional. It also looked very like a spider, if that is your intent. It could be scaled up and costumed, and would make a very convincing horror conveyance.
Huh?
The best beer cooler has already been invented, and it is called "The Canadian Beer Fridge".
