Planetary Drive

Pink fixed pulley, yellow satellite big pulley and green carrier create a belt differential planetary drive. Diameter of the yellow big pulley is double to the one of the pink pulley.
Six yellow small pulleys have same diameter. They are connected together by the black belt.
Using chain drive instead of belt one is better.
Input: green carrier rotating regularly.
When the yellow small pulleys reach highest position, their red plates are vertical. When the yellow small pulleys reach lowest position their red plates are horizontal.
The video also shows that after using the worm drive for adjusting the direction of the plates the situation is reversed.
