while the headline is technically correctly phrased, it buries the lede on the interesting bit here: the bi-directional feedback mechanism. robots that walk/run/jump like humans have existed for decades, but a bipedal robot that literally mimics the movements of a particular human, and sends force feedback to that human for real-time control is novel. that’s the neat part.

I subscribe to a small channel on YouTube and the channel owner had a very impressive demo of low latency bi-directional teleoperation. He's got some Cheetah vids so I'm guessing he at least contributed some code here if not control/hardware. https://www.youtube.com/watch?v=FnQGPGG-vuQ https://www.youtube.com/watch?v=FnQGPGG-vuQ I feel creepy posting this for some reason but if you have even an inkling of the complexity it's a crazy demo that I had to share lol.

  That channel owner, Ben Katz did the mechanical hardware, motor control PCB + firmware for the MIT Mini Cheetah as part of his PhD, here is his blog post on it[1], which links to a full technical report. The latest firmware is here [2] [1] http://build-its-inprogress.blogspot.com/2019/03/hello-there-mini-cheetah.html http://build-its-inprogress.blogspot.com/2019/03/hello-there...

    Ah! That links to the thesis folks were talking about in the comments. Thank you!!! Also, geez. That's a lot of (very impressive) work.
