Automat seesaw...

.....if we replace the two monkeys/ masses from :

.....with two masses , playing each one , on a separate belt arrangement (see yellow colour ), as seen at :

.....as a resembling first line image , using steam as its working fluid , you can see at :

Our problem can be to replace (fire+water=steam pressure ) with (continuous gravity unbalance+free fall=gravity "pressure") , in a simplified design (minimum number of spare parts ).

Yes Alex

" in a simplified design (minimum number of spare parts ) "

     Hi !
Conceptually ,as a general idea , when you play seesaw (fulcrum,bar,two masses) , you apply the principle of variable / oscillatory leverage.

As you know , there are three classes of levers...the variable/oscillatory leverage , is alike...

Starting with this image , we can develop a variety of automat ("self") motion models , due to ("free falling") gravity unbalance...switching ,every half-turn ,the torque difference (gravity "push" ) on the same side of the fulcrum.

Enstenow , as I see , you have a proposal on this line...so , good luck for your test !

.....is a non difficult evolution , development of a simple machine (lever) into a self-moving simple machine , due to inertia and the continuous gravity unbalance.


Thinking about the millions and millions of existing seesaws (fulcrum +first class lever ) , we can use them as "frames" and play variable leverage , if we add :


-a stable/fixed mass (fixed on the constant arm).


-a sliding mass(oscillating to and fro ) on the variable arm.


Variable/oscillatory leverage is a natural phenomenon ( motion of the celestial bodies/masses) , ...and so , becomes a common "intellectual property"...


Because "they" stated  the "impossibility" of this kind of motion /devices as "triple"...we can triple our designs (three kind of levers...variable/oscillatory leverage ) , also.
