Obama's Flow Is Adequately Hydrated

[BrooklynBay]

It's like the difference between using a mouse, trackball, and a touchpad. It seems awkward to use at first, then when you have the feel of it have to get use to using something else.

A search on Google came up with some interesting results:

Yes but when we use a mouse or a trackball, we're not being bounced all over the place.

On the trails, when you hit an unexpected rock or throw a tire into an unexpected hole, you're body gets thrown around pretty well even with seatbelts. Well if I had a joystick with say a 5-inch throw from full left to full right, I think that stick would be all over the place once the vehicle hits that unexpected bump. On the other hand, on a steering wheel, depending on the volumes of the components, you could probably turn the steering wheel 3 inches and the vehicle won't be off-course too much. The amount of precision required is even greater when straddling a rock or balancing a tire on a rock. Watch a few rock-crawling competitions and you'll see that sometmies, the amount of error is typically less than an inch or else the vehicle will be off the "line" and will be hung up.

I used to play an online tank game sometimes for 10 hours straight, so I'm a big fan of joysticks -- I played the game so much I replaced joysticks every 3 months or so. You're idea of the joystick is an interesting concept and is "thinking out of the box", but I don't think a joystick would be the right control in this situation and environment.

BTW the images you linked to only show these green faces with a tongue sticking out.

EDIT -- nm your images work now. wasnt working at work

Besides, you need that steering wheel to hang onto when bouncing all over the place.:

Nope, if I was the Senator, first I would be slurring my words because I would be drunk, and I would lie to you about everything even if it didn't matter one bit. Then, I would just plain make stuff up when I could not find any facts to fit my latest crusade. My family is from the Ohio Kennedy's, farmers and landowners. You know, working people.
I guess I should talk about your project, which I think is very cool. I would love to see that when its finished. You could get the front tires wedged in between two rocks, turn the wheel and crush both rims at the same time! Now thats power!

Is rear steer next?

Is rear steer next?

Maybe next year along wih a 4-link.

 

[BrooklynBay]

The joystick idea might work better if it had force feedback to give a more realistic feel of the road.

 

[j602]

Joysticks are for rear steer.

Setup looks noice.

bah, im just gonna keep it easy and do assist, not full

We've changed a lot and then some - some
You know that we have always been down - down
And if I ever didn't thank you - you
Then just let me do it now

el removable hydro steer - floating on rubber bushings. Dont say the diff cover is taking the load from the hydro cyl cauz its not! AHH!!! All of the load should be going to the two outter bushings and then on to the axle tubes (tube.. tube.. hmm, tubamama? obomobo? saxamaphone!!)

SOME people say I dont edit my posts enough.. so this is an edit
These things below are being made on the lathe as I type -- we'll see where these go later in the show.

Steel bushings? If not I forsee problems. Top view of your model needed, it looks like your ram is in line with your axle tube?

Have you seen this one? My friend Nates setup, he goes by Sceep on here but doesnt check in very often. It also acts as an axle truss.

The bushings are rubber -- heh sorry I didnt mention that. They are the same rubber bushings I used on the links.

Here's the top view

The hydraulic cylinder is inline with the link that currently attaches the two knuckles together (using SkyManufacturing's hi-steer arms).

Quick question Brian1, what axle is that? A d60?

Which CAD program do you use?

 

[IZwack]

Which CAD program do you use?

Its not a "CAD" in the traditional sense of "computer aided design". The software I use, called Maya, is aimed more for movie production -- think along the lines of Pixar movies like "A Bug's Life", "Finding Nemo" and "Toy Story" -- all modeled and animated in Maya and then rendered in "Render Man". I use it because I took a few courses in animation in my undergrad and also I can model faster in Maya than I can in say AutoCad. Maya used to be owned by Alias|WaveFront but I think now its under Autodesk (same ppl who do AutoCad)

 

[BrooklynBay]

I guess you could use symbols from Autodesk too? Do you have any threads on how you draw these images?

Yeah you can export objects from say AutoCad, or whatever else 3d program your working with, using a universally accepted format like DXF or whatever you like, and import them to Maya.

I don't really have any threads on how I make these.. but here's a screenshot of what this looks like before its "rendered" (rendering is when the computer takes a "picture" of what you've made in the 3d world):

In the screenshot, you see four quadrants. Three are "orthographic" (its in 2d) and one is "perspective" (the upper right -- which is in pseudo 3-dimensional view).


BTW the image I posted in post #32 with all the gray cylinders and the dimensions is not done in Maya -- I did that in Adobe Illustrator which is a 2d vector graphics program (pretty much the industry standard when it comes to 2d vector graphics).


If you want to give Maya a try, you can download the Personal edition which has everything you need to model hard surfaces. Go here: http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=7639525

Yes, a D60.
