A few things going on with this one that might not be obvious.
I'm controlling it with a headset that tracks my head and eye movement. It also has cameras in the eyeballs, streaming a stereo feed back to the headset. Where I look, it looks.

Another stewart platform for the mount - they're great for getting fluid and responsive motion out of cheap servos.

@ancientjames Oh wow, I can't remember ever seeing anything like this before! So it's basically a triangular antiprism of actuators. (It kind of tickles a memory, though, maybe of seeing some sort of stabilizing platform on a ship?)

@varx Once you start looking, you see it everywhere. One nice feature of a parallel manipulator like this is that the overall position error is just the average of all the servo errors (so tends to stay small). With a conventional robot arm, the error is the sum of all the individual errors (so tends to get large, without pricey high quality servos)
