Hey that looks like SJCC, but it’s not. They just remodeled the ceiling like that. SO much better for rigging now.

What is that? Is that something from the newest Star Wars. I swear those idiots are a bunch of brain dead morons. How you take a good franchise like starters and turn it into a dumpster fire with garbage like this doesn't make sense. Also WHY DOES IT HAVE TRACKS!!!!????? Its starwars!!!

tread spee ders are stupid. You can hover above the ground...why would you go BACK to treads.

Because repulsorlift jammers are a thing.

I don’t know what you’re talking about but you sound legit.

But these tread speeders can launch you into the air!

The stuff hanging from the ceiling, truss etc... We put it up there with boom lifts and motors. SJCC is San Jose Convention Center, they have the Silicon Valley Comic Con, looks just like that, Adam Savage goes to it .

Apparently this picture is from some event in Chicago, I’m assuming at McCormick Place.

Yeah I hate it in movies how they have tech to cross the galaxy but other stuff is like 1960.

I’ve only worked in the Bay Area and LA but Chicago has a busy con center from what I hear.

And yet interdictor ships still aren’t canon.  SMDH

Not to excuse things, but one of the droid tanks in Ep II had treads. As do (canonically) the astromech droids.

You could actually steer this the same way as some tracked vehicles in our universe: track warping. Reasonably effective on the Universal Carrier and I think some others. Not only that, but possibly constricting/expanding the bogies on the bottom in such a way as to change the aspect and grip behavior of the contact patch.

What exactly is track warping? The universal carrier has two tracks, right? 

user314 > HammerheadFistpunch 12/30/2019 at 16:09

Yeah they are . Several of them appeared in Rebels , which also introduced the Quasar Fire bulk cruiser/light carrier into canon as well.

Why did the AT-AT and AT-ST have legs? Why did the MTV-7 have rollers? Why did the MLC-3 have treads? Why are Rebel fighters streamlined?

Two, though the Hailfire had wheels/hoops, so that’s a judgement call on if it counts.

T he Treadwell line and the LIN minelayer both had treads too , come to think of it.

Apparently the UC did both:

Small turns moved the front road wheel assembly, warping the track so the vehicle drifted to that side. Further movement of the wheel braked the appropriate track to give a turn.

AT-AT and AT-ST are true all terrain vehicles capable of traverse the roughest terrain out there that is too intense for speeders to be effective. Having one single tank tread with no way to steer is just in sanely stupid design with no way to even justify it. I understand your point and its valid.... up to a point.

The universal carrier has two tracks, yes, but tracks flex more out-of-axis than people think. On the universal carrier, it steered with a steering wheel. The first travel of the wheel would slide a crosspin left or right to move the top guide rollers and/or the forward bogies (can’t remember) If the top guide rollers or bogies pushed left, it would mean the track was actually sort of slanting right over the front guide wheel. Because the track can’t really flex into a curve as it’s going over the front guide wheel, this means the whole track curves. If the whole track curves, the vehicle travels in a circle at the curve radius.

Obviously that’s not a way to steer tightly, so if you pulled the wheel all the way over it would engage that side brake on the diff. Mechanical Ford truck brakes.

If you had a vehicle with a single wide track, it could push the middle left or right. It is a thing.

Interesting! I knew O pponaughts would have answers for me lol

I didn’t even know you could do that!

T he A 6 Juggernaut Turbo Tank had wheels.

Don’t look too closely at their computer tech then.

AT-AT and AT-ST are chiefly used to inspire fear.

I always forget about the Jug, or get it confused with the HAVr A9 Floating Fortress. Hmm, in looking through GIS I’ve found the below recognition guide, which includes a PX-4 Mobile Command Base I don’t recall before. Interesting.

There was a German half-track that also (kinda) used it during the war, but it’s been abandoned since then. It’s an interesting bit of engineering, but not really useful for anything.

Thank you. I was trying to find a clear understanding of how track warping worked, but nothing on Wiki was this detail ed.

It is not totally unknown for tracks to even * need* to have a little off-plane flex for the suspension to work. Horstmann and its variants (like the British Cardan 3-wheeled “Bright Idea”), volute systems with inline arms (most US WWII tanks), Christie suspension (T-34, Crusader), and torsion systems like most Panzers can actually track the wheel straight up and down, but with some others, the bogies (and thereby the track) actually move in and out with suspension travel like a car.

Recall also that the track has to tilt to match the ground surface.

All that adds up to the track typically having a narrow enough drive so that it can do all that flexing without being sloppy - and that capacity for flex makes it possible to warp them.
