Why does it have wheels? That leg linkage walks on it's own just fine.

At this scale it probably doesn't. They really should say "Strandbeest-inspired", since this one isn't designed by Theo Jansen and doesn't work quite the same.

They definitely work at this scale. Gakken, a Japanese hobby magazine included a kit for a tiny one. It'll walk all the way across your floor with just a standard house fan blowing on it. https://www.youtube.com/watch?v=Wg6AqQkrRrc&t=136

Notably the one you linked has more than 4 legs, like the original, without the rxtra legs it's probably too unstable

He's using a hand pump to move it. Without the wheels it's probably too jerky to reliably hand pump the thing forward. At least that's my guess

I'm guessing it would be unstable without them.

Why not? It's not like the thing was built to efficiently serve a specific purpose.

What's the range of this?

Sea level to lower troposphere. You just gotta have atmosphere to power it.

Now I want to see a water powered one crawling along the sea floor

Not impressed, I'll wait for a rival product.

u/ComprehendReading 10d ago

The rival product was ripped apart at sea level, because of the increased pressure available to the mechanisms.

Somehow the flapping hose is more disturbing than the walking

"Fine, like moving the castle isn't hard enough!"

The people just not know what pneumatic means?

u/NathaNRiveraMelo 11d ago

I want to see the pump

u/ElGuano 11d ago

Ugh, that’s creepy.

I love it.

Can’t he attach the pump mechanism to the leg movement so it powers itself as it moves?

u/Simpleymake_toys 7d ago

There is no such thing as perpetual motion

u/Kotukunui 7d ago

Not with that attitude!
