Tell me flaw in this design

Mr Chip,
I am very much surprised that your kind of expert is raising the unimportant questions.a wall near the pivot point of each seesaw and curved shape of each seesaw will work to stop the ball due to gravity.when the ball stop at a point then a lever or motor will work to lift up the left hand side arm of seesaw and ball will get started rolling down towards right side seesaw due to gravity.in this design gravity will work to push the ball and stop the ball.

Unfortunately I do not understand your description of the mechanism, and I doubt anyone else has been able to understand it either. I've asked before - please provide sketches that show the position of the seesaws, the center bridge and the ball at various times throughout the cycle - similar to what I did back in post #13. Can you please do that? It doesn't need to be pretty. Thanks.

See the link and tell me input and output.the front part weight is 150 gram and small ball weight is 20 gram.the front part is lifting up 5 centimeter after dropping the ball and the height of system is 10 cm.from the surface when it is balanced.

Where do you see similarity between these two devices? Calculate input and output using potential energy formula and tell me.

From the video I see you putting energy it the system, when you lift the ball. You claim the energy that you put into the system is less than what you get out, but I don't believe your measurements are accurate. Please reshoot the video, this time with a ruler placed next to it so we can see how high you lift the ball (it looks to be more than 10 cm) and how high the heavier end is lifted (looks less than 5 cm to me). Thanks.

On the dance floor, baby!
And account for friction...

Hello Mr Chip,
I just used these figures to avoid points.
The actual figure s are .the heavy part is lifting up 5.2cm.
And height of scale to place the ball again is 12.8cm.
But my request to you that take the front load 15 kilogram and ball weight 2 kilogram.
Now calculate and tell me about your calculations.
Thank you Sir!
