Hi all,
I just came across this http://www.youtube.com/watch?v=R8NXWkGzm1E
So I thought instead of using batteries to power it why not use magnets?
I believe a smot (http://www.youtube.com/watch?v=vvhX7BF9pL0) will work on this device.
You would have a smot on the track top and bottom where the ball rolls..
the smot must only be strong enough to roll the ball horizontally, the smot must not be strong enough to pick up the ball's weight.
the top and bottom track should have a little more distance than the picture shows so the ball falls a bit more so its away from the magnetic field of the top smot.
So when the device flips the ball falls to the bottom smot and the process repeats..
any thoughts?
Anyone?
please i am dying for answers here :)
It is not possible. Sorry, I have seriously thought about it as well as the concept and I can not see how it can work with only magnets. The smot will only allow the movement in one direction. The center would move against the smot when reversed making it stop.
ok :(
thanks for the reply.

I know something that may work, and needs to be tried. I will build it in two forms, the flip and a circle version. Using back to back double cone tracks. there may be a problem with the flip and be a touchy problem to continue the flip so I decided to do a circle version . So you might say I am joining you on this one for it looks fun.

edited to clear up my writing and add the circle version.
AB Hammer awesome! :)
Keep us posted
The original idea would be an excellent design for a robotic rover spacecraft on a "windless" dry rocky body liked Mars, Moon or larger
Asteroids. It gets you above the dust and muck. Why have the camera mask up there when the whole rover could be?
It's in a class of the "footed wheel" rovers.
Now back to our regularly scheduled broadcast...

I believe the video is faked :( for this reason....... If the motorised cylinder is heavy enough to lift the track, how does the track lift the cylinder?
Bumblebee I think you're probably right.. :-/

I will have to disagree. It looks real, and the tracking lifting the cylinder is a fine balance and the action of the motor shifting the weight in the cylinder is trying to climb as it flips angular momentum helps to create the action.
The weight in the cylinder must be on an axle with the weight spinning around it. As the weight at the end is in its furthest position it flips and when the weight is in its least position the track lifts the weight due to its position. I do think it maybe under a controller due to the jerky action but it doesn't have to be.
To duplicate as is. This would be my approach.

PS FreeEnergy; Don't give in so easy.
Chastisement LOL
AB Hammer,
I have not completely given up just yet :-)
Yes,
If this were stopped vertically and wanted to start itself again it may be in a somewhat of a bad way. But the upper ladder
would try to take the track over-center when in motion...then the roller could then make progress. Assuming the geared
power source could lift itself vertically.
