any tiny error in your calculation could have easily multiplied so you have to make sure your numbers are exact.

Also, calculate all the true values experimentally. Each part has some tolerance, and these build up, and make your theoretical calculations inaccurate.

I'd like to implement adjustable steering in my buggy for next year. So in the video below, Nestor revealed his secret of caliper steering.

Would I be able to use this kind of steering without the electronic caliper?

Its the same thing as the threaded rod steering thing, its just implemented thru the pillow block instead of the entire chassis as a whole

Dial calipers are not electronic.

Oh OK!!! I will definitely do more research into caliper steering then.

Did many of the national teams use scopes? Or just align it through 1 stick and wood dowel?

Any other interesting out of the box thinking?

Yeah, they used rifle scopes. I should have thought of that ;) . Would rifle scopes still be useful next year, even though there will probably a curving component?

Yes you still need to aim towards something when you set up your vehicle to curve. I used a laser with my EV, but a rifle scope does the same thing.
For reference, 1st, 2nd, 3rd, and 4th all used lasers to aim EV in 2017 at nats (idk about the rest, I just happened to be friends with 1, 3, and 4)

Please note that for BB, you must use a non-electric sighting / aiming device. So no lasers.

I think that almost all top 6 teams used a rifle scope at nationals this year.

We did not. But it worked out perfectly fine tbh. I think we were like .2 cm to the right of the "center" of the centerline, and we were 3 cm short ish :x for some other reasons but yea

For aligning w/o scope, it took some practice. Maybe using a scope would have made the process less stressful and a bit easier.

You can use them probably. When scrambler had bucket they let you move the bucket to sight. Only issue with curved track is you will need to be able to measure left or right of the center line depending on distance (if your car has a fixed curve).

We didn't use one btw (we got 5th)

Im not sure about Kennedy, I saw their run (when we were running). I didn't really pay attention, but I'm like 70% sure they ddin't use a scope either.

I am still kind of confused about how this "threaded rod steering" works :( ... could someone clarify more? :?:
