The automaton's sequence of movement is as follows:
1 - The king's left arm holds a large beer. His arm raises the bottle across his chest above the glass. The wrist then tips the bottle to pour a drink.
2 - The arm with the bottle returns to his side.
3 - The right arm holding the glass is lifted up to his mouth.
4 - The mouth opens to accept the beverage.
5 - The eyes drop to the glass to confirm it is empty.
6 - The eyes return to looking ahead.
7 - The mouth closes as the glass is returned to resting position.
