My solution to "Back and Forth". Too many parts but decent speed. It's a work in progress.

This is honestly sort of an interesting look at the design process. I was trying to do something a lot more like what you have, but the balls kept accidentally getting stuck in the wheels and squished into the undercarriage. So I just designed it to let the balls go down there, and pull them back out if necessary. You managed to keep them from getting down there in the first place. I am now realizing I could probably just replace my second wheel with a ramp and achieve similar effectiveness.

Sorry - it seems to be hard to copy the links; that happens a lot. Fixed in the original post now.

Balancing Act in two pieces. I've also seen a complicated, 2-part thrower-and-catch solution.

You get points because the payload stays in the target permanently, though.

Not super clever, but it gets the job done.

I'm also surprised nobody else has suggested getting Big Ball done with speed. Torque Multiplication FTW! http://FantasticContraption.com/?designId=929843

EDIT: Um, apparently I missed page 3, because there are a few of you who sped in under the ball already. I still like mine though, as it's the only non-thrower I've seen to do it.

Weird... I am working on this design in which I replaced a powered wheel with an unpowered one, then changed back but it acts different now. I didn't change the node position at all, it's just now the connecting bars are hidden behind the wheel and before they were on top. Really weird.....

Anyone else experience this?

Yeah! I verified it, I deleted the bars and put them back on top of the wheel and it acts like it did before! That's not good....... boo!!! bad inconsistent 2-D physics. Fantastic Contraption game, go in the corner

I've always had to redraw all the connecting bars to replace a wheel in any of mine. I haven't been able to make a new wheel attach to an existing node. Maybe it wasn't actually attached.

Well it was... because it was supported by it. And it stayed on. It just acted differently when it hits this ramp I made

I can't take full credit for this one. It's someone else's design featuring my modifications... and a bug or two. Good for a laugh.

I fooled around trying to scavage the failures but wasn't as elegant as you at it... so I sealed all the holes. Neat solution either way.

So what's the simplest Back and Forth solution? My 12 pieces seems pretty efficient actually. Any less would seem to require a totally different approach.

http://FantasticContraption.com/?designId=980385

EDIT: Well, I managed to cut two more, but I think that's all I can manage

http://FantasticContraption.com/?designId=980721

EDIT 2: Ok, now I have 9. But that's all, I can't think of another way.

http://FantasticContraption.com/?designId=981004

EDIT 3: 7 -- And a Bonus! Now it's self-contained!

U-turn in 8 pieces. It's tough to make it simple because it needs to give to get around the bend.

I finally got into it last night at home and I'm "sort of" glad it blocked at work. I have work to do.

My wife was a bit miffed that I dropped everything else to play a comuter game.

I modded it and got 6 pieces! Lost the loose ramp stick and adjusted the front 2 wheels. to kick the ball in. One version had the ball sitting on the far right wheel for a bit as it developed spin enough to roll on in. For some reason I cannot link to it.

I've been playing with this for a while (maybe too much!!).

So far, my favorite has been the contraption that gives up, breaks itself, fixes itself and completes the puzzle!!

No, this was NOT planned.

Hey Everyone,

I’m working on the “Unpossible” task and thought I’d share the following as an example of what not to do:

http://FantasticContraption.com/?designId=996300

I’ve been trying to get away from ramps as they consume a lot of space and well, just aren’t that interesting but Fantastic Contraption physics seems to frown on levers & pulleys.

Did you save it? If so, go back to the main menu, go to my designs, and from there you can select "link to this design", and copy/paste the URL. If you didn't save it, you'll just have to make it again :).

Um, no, you've linked to some sort of truck device on "Junkyard". It must be a Jeep, because in addition to being unable to climb the hill, it spits out a random engine part in the process.

I counted the object ball, because it's integral to the design and not just a passenger, but I guess we are calling that 7. Does anyone have a simpler solution? No amount of tweaking would make the basic triangle work for me.
