Adjusting steering

As a different curve would be needed at 9 meters than 12 to maximize bonus, I assume people will be attempting at adjust steering prior to a run. I have seen some caliper ideas from div c but wondering what other ideas people had to micro adjust their vehicles steering.

Or run it to maximize bonus at 12 meters and set steering there and take a slightly less high bonus score as the distance decreases to 9 meters?

The caliper steering system is an accurate system for steering that works exceptionally well when adequately mounted and calibrated. If you have the time and resources to do so, it would be a good idea to use a caliper system. However, the section of the rules regarding electronic components (3.f.) does not allow electronic measurement of any kind, excluding a stand-alone calculator, so, most likely, you will have to compromise to a vernier or a dial caliper, instead of a digital one like those used in division C. This leaves more opportunity for human error while setting up the buggy, especially under the stress of competition.

If you built the buggy to only have one steering setting, you could expect to be able to keep up with other teams with adjustable steering at some less competitive invitationals and possibly regionals depending on how competitive your area is. If your team is in a more competitive region, an adjustable steering system would be well worth it.

You should also make sure that whatever system you use, it can be set up quickly enough for two runs in eight minutes.

tried and tested
Were calipers even in common use before Bazinga+ popularized them?

I guess that my choice of words implies longer term use. I'll fix my word choice. However, I have seen quite a bit of experimenting with the concept recently, but I don't know about how extensive the use is in other parts of the country.

Haven’t heard of any calipers near me

Is this a front or rear axle steering? Any reference documents / links on this caliper steering.

Thanks

I think front. There’s a few videos on YouTube.

What a legend... Though I didn't know that he made calipers popular...

No documents exist that are known to me... But this video is really even better than a document. Nestor also answered a few questions in the comments, by the way.

Why do you think a dial caliper isnt as effective as a digital one? They have nearly the same precision and accuracy for the most part. The SAE team at my school mainly use dial calipers and from what I understand, they were pretty common in industry before the digital caliper. I disagree with the idea that a dial caliper cant be just as effective as a digital one. The real hard part will be locking the caliper in place, because plastic dial calipers dont have the set screw like the stainless steel digital ones used by most of us in EV
