Hybrid hydrostatic transmission enables robots with human-like grace and precision
http://phys.org/news/2016-05-hybrid-hydr...obots.html

Quote:A new type of hydrostatic transmission that combines hydraulic and pneumatic lines can safely and precisely drive robot arms, giving them the delicacy necessary to pick up an egg without breaking it.

This transmission has almost no friction or play, offering extreme precision for tasks such as threading a sewing needle.
The hybrid transmission makes it possible to halve the number of bulky hydraulic lines that a fully hydraulic system would require. Robotic limbs can thus be made lighter and smaller, said John P. Whitney, an assistant professor of mechanical and industrial engineering at Northeastern University, who led the development of the transmission while an associate research scientist at Disney Research.

So... can this be scaled up? Can you put wheels on it?

Yes, and yes. You can see them on lawnmowers, and even tractors- https://www.google.com/search?q=hydrosta...ansmission

Sweet! I can mow the lawn with a mech!

I can see some very fun applications of this technology. Just imagine a robotic boxing game with a virtual reality headset like the one shown in the video, for example. Big Grin

when do I get my mech suit with rockets and lasers? I need to budget this in time for my next birthday.

Am I the only one here that not only knows what a swash plate is, but also knows what a fixed unit overspeed entails ??

No..... though I only know the terms via literature.

Thumbsup Nice to see you still around. Smile

He is deformed, crooked, old, and sere,
Ill-fac’d, worse bodied, shapeless every where;
Vicious, ungentle, foolish, blunt, unkind,
Stigmatical in making, worse in mind.
