CG Showcase of Overbalanced Wheel

[johnny874]

  helloha,
if you want to try something that might interest you, try over lapping
2 circles and have them rotate in opposite directions.
If you have them over lap at 45 degrees from bottom center, that point would move straight up if there was a slide between the 2 points.
This would mean that the opposite point of either circle should have more potential when moving from 45 degrees from top center to 45 degrees before bottom center.

at first thought inserting just a ramp should be fast and easy, but no, end up have to adjust almost all the internal structure of the wheel, then have to trial and error to get the timing for the ball rolling off the ramp right....  .... need to rest

the idea on opposite direction is a very good one, try first test but got problem (think its a software bug, anyway its complex, alot of headache), give up

  I'll post a drawing tomorrow helloha. not sure how doable it will be but should give everyone the idea.

                                                                                                                                   Jim

  helloha,
in this example, the distance from center line or axle to center of mass for the weight on the left is a distance of 1 (1 meter, 100%)
and is lettered A. With B, the distance is .7 (70 cm's or 70%) of A. The difficult part would be to transfer the force of the weight from
1 wheel to both wheels and then back to one wheel.
The line B would have half of the weight's mass on each wheel while it is being lifted straight up. Not sure how it could be put into
a working concept if it is possible. i have bought wood to make a routing table so I can start work on the 4 weighted wheel you modeled for me.
I'll be making it with 8 weights and will be building 2 different wheels. The wheels will use the same basic principle but one will have more detail allowing it to work faster (hopefully). Not sure how long those will take to make.

                                                                                                                                      Jim
p.s. what might be an idea is to have the weight move from one wheel to the other and do a figure 8. but 2 weights should suffice.

edited to add; may consider a 4 weighted wheel trying to replicate the model you posted a few posts back. think it would be kind of cool to
show that your modeling does help that much and to see how close they actually look when compared to each other.

just did a extend of the ramp to see how's the balls perform
