Ah nice I've tinkered a bit with robotics few years ago, e.g. https://twitter-archive.benetou.fr/utopiah/status/1760260544... and it's pretty empowering... but also showcases how amazing the human body is. Our dexterity, ability to sense, etc.
Reminds me of https://rodneybrooks.com/why-todays-humanoids-wont-learn-dex... which is basically a stark warning against the hype.
Cool video! What made you stop if I can ask?
And yeah I feel you re humanoid. I worked on the Rubik's cube project at OpenAI, which used a humanoid hand, and it was insanely painful and hard. Also fun anecdote: it was completely impossible to teleop the shadow hand. We had a data glove to capture hand movements but as soon as contact / haptics come in, you're lost. We could never even get a single rotation on the Rubik's cube via teleop.
I do think simpler hardware like the one described in my post works really though and it's so much easier to do something with it.
