Nice! This is the sort of creative technical innovation I love to see. A simple yet highly effective use of mechanical systems to gain handling benefits that doesn't rely on electronics or computing power. No AI, no fancy algorithms and no need for timing critical programming- it's all just physics and natural phenomenon put to good use. I do like highly complex electronic and computing related systems, but sometimes it's just so much more satisfying to see a purely mechanical system work in such an elegant way.

All things engineering are splendid to me.

Thanks for the interesting video.
