DIY Bipedal Robot Used Pneumatic "Air-Muscles" Instead of Motors

This is what non-commercial tech looked like back before the gold rush and vulture capital. Geeks and nerds in basements doing weird stuff that would be laughed at by most people on the street. Most STEM professions were middle class, not lottery tickets.

Makes perfect sense, in nature you have a lot of both practical and odd functionality out of filling "bags" with air or liquid.

This is a pretty cool approach. If they can improve the visual presentation it can also look pretty awesome. Gives me some inspiration for drawing scifi designs too.

I would love to see this with nitinol wire muscles.

Power use would be immense and it would be insanely slow.

Considering 90%+ of the input energy goes to heat with NiTi actuators, Your walking robot would also double as a great space heater.

Power use might be high depending on configuration, but speed shouldn't be that slow using capacitors. Sufficiently strong pneumatics tend to require quite a bit of power too.

I opened the article expecting it was going to be about clone robotics https://youtu.be/5mSE6Tkhy4g?si=tDp0DUI9OOXAwsX2

Cool... their biggest failure pushed them to find what they are actually good at.

It's robot from 1990 and no, there is no video of the robot actually walking.

A guy named Walker developing legged-robot software is even more on the nose than a guy named Karpathy developing autonomous-vehicle software.

Oh my god, how have I never noticed Karpathy and Car-Path-y? Amazing!

A noble principle, albeit not without its lamentable failures.

Car-(em)pathy... Now I can't unsee it!

Thanks.
