This one is about as clean as you can get:

Yah, I went browsing after posting my solution and saw it. :grumpy: Well, mine is clean and has at least one piece!

I wonder if I can use that sweeping idea with my clean solution....

The extra annoying part is that I tried (unsuccessfully) to do that -- on robotic block. It didn't even cross my mind to try it here.

Not my most elegant design, but on Gantry I managed to drop the third rectangle between the other two. (I also learned that the entire thing is the goal piece -- it's not enough to just get the rectangle in)

At first, I wasn't sure what all the water rods on the right were for. I thought about using bracing for the verticals but wanted to see if I could do it without them.

Here's a different method for lowering the target onto the pillar:

I know what you mean about the goal piece. my initial try failed because I didn't take that into account.

If I had another week to work on it, I might try to drop the piece more cleanly in the middle without having to rely on supports. I'm not entirely sure it's possible, though; at best it would be a very tight fit.

I confess that I sometimes enjoy contraptions that unfold. And that method was by far the most convenient way I could find to get the wooden bits where I wanted them.

Here's what I came up with in the way of supports and dropping the piece between the pillars. I know that it is not exactly necessary to have the pick up to go out and back, but It was just one of those things I want to try.

Okay, I admit those are better supports than mine. :tongue:



Edit: I thought I had an 8 piece solution, but alas I have confirmed that
2 * {Rectangle width} + {Rectangle length} > {Goal width}​
:frown:

Okay, I just had to post this one.

A crackpot's dream brought to fruition : A perpetual motion drive using magnets(no powered wheels):

Hehe. :smile:

It got stuck after a few trips so I tried to add a new piece to help -- and boy is that design unstable. It must've taken a lot of tweaking to get it to make as many trips as it did!



Oh, new free level!

It took a lot of tweaking to get my first, and only successful solution for this one to work!
