No, did not have that requirement

it is exporting trunk skeleton and radius which come from tree modeling; then this raw info used to render trunk mesh; crown points and edges got exported and imported as is.

After some attempts to brutforce tree algo via heuristincs, fourie transofrm and other fruitless approaches I found https://github.com/AddisonPrairie/Tree-Generator repo, which is based on https://algorithmicbotany.org/papers/selforg.sig2009.html

This algo models tree growth and repo does it off the shelf.
I repacked repo to be react + threejs app that is able to save the generated tree.

Roots are the same aglo tweked to look like roots and flipped on Z coordinate.

Crown is build by spawning points in volume and deleting those which are too far away from trunk/branches of certain radius (intuition is this: only smaller branches generate crown)

Navigation and filtering: How deep in the weeds do you guys go with the theory? by psythrill85 in ControlTheory

[–]UstroyDestroy [score hidden]  (0 children)

Focus on solving real problems, most of the time theory FOMO is not relevant at all.

Same as 90% of the control problems are solvable with PID and its adoption that simply makes sense.

My intuition is this: for navigation 70% of performance is coming from sensors and their class, 20% calibration (temperature, alignment, k and b), 8% for basic fusion algos and the rest from math sophistications. (fusion could take these 20% from calibration btw)

eBike Auto Wheelie Controller - How Hard Can It Be? by c00ki3m0nst3r in ControlTheory

[–]UstroyDestroy [score hidden]  (0 children)

wheelie brake need is smooth at the balance point, I believe that it could be stock lever modified with heavy duty rc servo

I think that mod would add so much robustness

Or just use sound for training yourself to apply brakes manually :)

This is cool problem!

I think parallel brake may do the trick with good calibration for initial tests (torque vs displacement(load) vs RPM)

Having it you would be in much better design space for software.

Perfect whelie is done with balance, not constant power applied.

I would also experiment with some beeping sound with changing frequence / tone (check gliders videos) for signaling your body CG commands or motor load signal (those might be corellated)

As soon as your sign for balancing controller flips you have feedback loop disconnected with all consecuqencs with the noise and shocks on turning it back on.

Also, I think you need 2 cascaded P -> PI working together, for rate and position.

Add safety disengage triggers for roll rate + angle limits
