Super Sick - 56 transition controls for a triple inverted pendulum.
(1/1)
BrianHG:
:scared: Talk about some serious balanced motion control.
:scared: I still cant believe they got all 3 pendulum joint to stand vertically in position 7 yet alone make a transition from form all other configurations to and from the total vertical alignment.
Hawaka:
It is pretty impressive, but the real question here is: Were the transitions calculated or created by random try?
dobsonr741:
Been asked on the YouTube comments. Calculated + feedback. All 3 joints send position feedback.
BrianHG:
It does look like they have rotary encoders on at least the first 2 joints.
However, I could be wrong. To keep it completely frictionless, they probably need some sort of optical or very low friction contacts prom axis-pivot to the next axis-pivot.
Otherwise, if it is all load cell measured at the moving base, this it is too unbelievable. Because of other videos on Youtube, like the impossible miss basketball net, camera feedback is also possible.
Infraviolet:
Each of the joints has a bulky blue (perhaps 3d printed plastic) housing behind it. There'd be plenty of room in there for an optical or magnetic encoder, even if only a fairly low res quadrature one.
Very impressive work!
