Principles of Vehicle Steering by KayKove Principles of Vehicle Steering by KayKove
A quasi-tutorial on the principles of optimal vehicle steering for any budding transportation designers looking for insight into such details. In an artistic context, this information simply helps designers and modelers pose their vehicles realistically, but hopefully it will also enlighten a few people and give them another codex entry for their left brain.

Most models pictured are mine, sourced models have been identified as such.

Many thanks to almighty Google our founder, as well as dear Marian87 :iconmarian87: for his exemplary automotive recreations.

Inspired by MrJumpmanV4 :iconmrjumpmanv4:, whose castle on countless wheels recently excited my mechanical mind :-)

All the vehicles look nice as well (including the "buggy")!

Love your advice and perspectives on vehicular steering! The "buggy" looks like some futuristic armored-personnel-carrier!

wonderful demonstration. i knew half way through looking at this that you were inspired by our short conversation Xp
Flaketom made a truck that would be a prime example of universal turning here [link]. That was actually the main inspiration for my tortoise model.

Universal turning wheels is a great idea, i think the only reason it's not so commonly implemented is because of the added complexity. I'm aware that most monster trucks have two turning axles in the front in back. And the LAV-25 uses a similar format that you showed in seventh slide (four front wheels turning and the rest in the back stationary)

would you like the model file for the Tortoise via email to get a closer look?

Thanks for the feedback - I was worried you might take offense at this, which wasn't my intention at all. Here I was just trying to give an overview of steering layouts and possibilities and explain how it works best. Flaketom's truck is the ultimate in that it could perform any number of these with ease. My little 8-wheeler isn't really intended to fill a particular purpose other than as a basis of comparison for different methods. In addition to your Tortoise, I had in mind vehicles like the Jeep Hurricane and all 3 generations of mar rovers Sojurner, Spirit/Opportunity, and Curiosity, as they all share the ability to drive normally as well as pirouette. The Jeep does this even without universal wheels. As for your Tortoise, the orthographic views you posted answered any and all questions I might have had as to your chassis design. Since all your control arm assemblies are identical, I would deduce that they would all be pivotable and allow it to articulate however the operator deems appropriate.

Gotchya, no offence taken =D
Btw, is the 8 wheeler you made for an example new? i haven't seen it before, looks very nice.

for my tortoise i was kinda planning on using the LAV-25 style of turning but i had already made the wheels able to turn independently, so i guess it could be capable of that gradual turning style.

Yes, this 8-wheeler was made specifically for this tutorial since the biggest thing I had was the 6-wheeled Mako and I needed a better demonstration piece. A few days of concept sketching in my free time and then maybe 6 hours of modeling, with most of the detail bits being re-purposed from other models. It turned out alright, although I don't really like the rear end, which you conveniently don't see much of here.

I see, imo it's a very nice piece. Would love to see some more work put into it if you ever want to get around to it.
