This second one i expected to look much better. It’s a more complicated 7 frames of movement forward. 1 frame back. 1 frame two steps ahead. 1 frame bsck.
So the angle of the arm goes 0-15. 14. 16. 15.
But it’s too smooth now.
It looks good for a shuddering robot and I might reuse this in the future, but not what I wanted.
