This is how I did it:

http://FantasticContraption.com/?designId=545306

I have to remember that I don't have to connect everything together. It's almost always more elegant looking in my opinion when you do it in stages and "drop" the parts once they have been used.
 
Physics news on Phys.org
There's some weird physics going on in this. In "up the stairs" I was experimenting with some stuff... I put a yellow and a blue wheel on the ground, connected them at all four outer points (top to top, right to right, etc), put the red wheel behind, and connected that to the center of the yellow wheel.

After some time, the physics starts to go crazy, and the contraption somehow launches itself at high velocity into space!

Aha, here's the link: http://FantasticContraption.com/?designId=676058

Some of the previous ones, I've pretty much just brute forced the wheels through, and dragged the red one along behind. :-p Though I admit I enjoyed making a catapult in that one level...



Aha, finally past the stairs. My contraption just wouldn't make it all the way up... so I built another contraption to give it an extra push from behind. :biggrin: http://FantasticContraption.com/?designId=676511

You could have added a wooded rod to connect the "axles", used two drive wheels, and had the red wheel ride on top:

or two wheels work fine with just a little traction:

or... Just bypass the stairs all together:

Solving level 20.

Oddly this takes advantage of what seems to be a glitch in the game in order to keep it in the zone.

What's the glitch? The game level extends (far) beyond the initial viewpoint: you can even zoom in/out and drag it around.

If you hit "back" after the victory notice to let the level continue, the "chain" drops down into part of the area it shouldn't. This seems to happen if the "links" are too short. They can also break when they are too short also.
 
looks like the physics gets wonky when driven simple harmonic motion shows up. I remember playing with some approximations for that a while back, and a numerical solution will usually diverge and have your pendulum swinging away at light speed in no time.
 
What's the simplest solution (fewest parts used) to keeping the ball in the goal box, in Around the Bend?

1 stick (from urs)!
http://FantasticContraption.com/?designId=718216

This takes >10 minutes

I don't think the ball will stay in the goal. It should push the other ball, ever so slowly, and eventually leave the zone. I suppose I have to let this thing run for an hour to know for sure...

Isn't better (Stick is too long// and assuming that costs are $/metre)
I have it on good authority that branches are sold by the piece regardless of length in that universe.

EDIT: Breaking news, it didn't take an hour. The 1-stick scheme failed to keep the ball within the goal area.

oops, I ran it for ~>20 minutes. It stopped moving

Better yet, http://fantasticcontraption.com/?designId=718066" also works by leaning one against the ball to make the ramp, but it takes so long for the ball to roll into the goal that you would lose patience...
My solution was essentially the same as this. Just move the ball so it starts higher up on the ramp. You get your solution in less than 30 sec.

[Smacks forehead.] You know, for the longest time I thought the target had to remain where it was, I didn't even try to move it. Duh on me! :rolleyes:

Took me a while to figure that out too.

Seems like cheating. I thought perhaps that was the bug you guys were talking about.
