The Physics of Clockwork
Mechanism
Winding a spring: KE --> PE; When
triggered, PE --> KE as spring winds out
There are also varying cog sizes to take advantage of the
different accelerations produced by varying sizes of cogs'
radii.

Spring force is calculated so that the energy stored in it
is sufficient enough for the automaton to run through its
full “program”.

The basic principles of automata are based on basic
clockwork, with the majority of them powered like
old-fashioned clock movement:
with a spring which is wound by hand.
