Step 5

Put in a bin

Into the bin

The chute rotates to the chosen bin. A door folds down to guide the falling piece into it.

The machine

Bins sit in stacked rings around a rotating chute. Each layer holds 18 small or 12 medium bins, and layers can be mixed.

The design files and the code are public.
