Evolution of the Shorty

Postby Wordman » Sun Jun 03, 2012 12:49 am

A couple of years ago, I posted the Shorty chassis on my blog. While it isn't great, I do like a few things about it. Namely:
  • It is simple, with only 23 parts in the base chassis.
  • It is quite posable, rotation on one axis in the neck, elbows, wrists, ankles and hips, and rotation on two axes in the shoulders and the waist.
  • It features a surprisingly strong connection in the torso (stud to center circle of plate), making the frame a lot more solid than you might guess.
  • It is highly customizable, with various places where one part can be replaced with a host of others for different types of load.
Also has some bits I don't like:
  • It is sparse looking, not quite filled out. Sort of amateurish looking.
  • The feet are too small, giving it a slight balance problem (not as bad as you might guess).
  • Some major wasted rotation. There are two connections (the top and bottom stud of the travis brick) that allow full rotation around an axis, but they are stacked such that they both rotate around the same axis, which is useless.
  • Hips only allow rotation around X axis. Would like rotation around y axis as well.
Here is a render of the original basic Shorty frame:

In this thread, I will be experimenting with variations on the Shorty, to try to make it into more of a modern, high quality frame.

Here is the Shorty mkII-alpha "Rufus" (.ldr file). It sort of went a weird direction when I was playing with the bricks, becoming more of a full-fledged chicken walker. Even so, the basic concept of its construction is pretty much the same as the original shorty, with a 90 shift in the hips and a different torso:

I love its articulation (both the torso and the shoulders can basically rotate on all three axes). Balance is also pretty good. With the elongated torso, quite a bit of room to tinker. I think I found a fix for the feet that works pretty well without over-engineering it. The whole thing could be a bit too short.

I suppose this configuration is d6Rd d6Rd d8Rd d6Y d6B.

You had me at "chicken walker."

I've always preferred digitigrade designs (GERWALK mode, Glaugs, Mad Cats, Vultures, etc.) and with my discovery of MF0 I've really come to like what the side-by-side 1xWhatever long slopes bring to a given frame's hull/fuselage. This MkII is very nice looking.

I like the simple, functional elegance of the shorty, and I really dig the MkII.

I've built one of the original Shorty frames for myself. I had a problem with the clutch between the pieces that made the legs and the Pneumatic T. I used the 1x1 Round Plates w/Hole to tighten up the connection.

I *like* the original shorty. It has a 'this is a fun game' look to it, I think, rather than looking amateurish. And so easy to customize!

However, as Wadmaasi points out, chicken walkers rule. I too am a huge fan of digitigrade designs (and +1 point to you, Wadmaasi, for using one of my favorite words) and I think this one looks great.

The new version totally ROCKS.

Oh, and with some slight changes to the arms and a huge gun on top it would make a great Behemoth from BattleTech.

Awesome, a Shorty Thread! I first was turned on to the design by zeekhotep's Crimson Commando version on the nobsjustabs blog. http://nobsjustabs.wordpress.com/2012/0 ... y-chassis/

I've been building using ideas from that as it has a bunch of parts I already had in my old boxes, before I got into this whole non-linear microscale thing.

Thanks for the feedback, everyone. Keep it coming.

I should have mentioned in the original post: if you have modified the Shorty, I'd love to see and hear about it here in this thread.

Also, some quick and dirty .pdf instructions for the Shorty mkII-alpha

Oh man, this little guy has got a lot of personality! I think I'm definitely going to be playing around with this design.

At what point does it become a new frame? From the Travis brick down, it's the same frame. Everything else has changed though.

That's be more of a philosophical question. To me, the arms are also essentially the same, as is the torso to center-circle connection. I dunno. If it needs a new model name… hmm… it's sort of a funky chicken, so name it after the writer of "Do the Funky Chicken" and call it the Rufus.

Here is the Shorty mkII-beta "Onager" (.ldr file .pdf instructions). This one is closer to the original shorty, though the pelvis is redesigned and the torso and head use different parts:
Image
Image
This one has a wider base and a beefier look than the original. Slightly more articulated than the Rufus, as the hips rotate on an additional axis, and the head is on a ball socket. I vacillate between thinking the head is really slick or really dorky. I thought about adding another plate with an axle hole below the neck (probably a 2x2 round), but the axle/towball part dosen't fit between the studs, making it look weirder. Same with using a technic 1/2 bush. The feet turn out to be surprisingly versatile and stable. I went back and forth on the direction of the legs. I think I will probably turn them around, putting the handle of the tile in the back.

I probably went a bit over the top on the plasma missile packs. Still, I wanted this model to be a boomer. The bit on the left arm is a target designator. Color scheme is an attempt at desert/scrub-brush camouflage. Initially, the colors looked a lot better, but it turns out they don't make certain parts in dark tan or dark green.

I suppose this configuration is d6Ra d6Ra d8Ra d6Y d6B .

In the brick, probably it would stand only because the weight of the missile packs would overcome the friction on the T-piece, and they would rotate down to touch the ground. Feel free to build it and see!

Here is the Shorty mkII-beta "Onager" rev. 2 (.ldr file). Moved the missile packs forward a stud (better balance), rotated the legs the other way 'round and changed/moved the head so it wouldn't get crushed by the missile packs. You can't tell from the picture, but the head remains on a ball socket.
