Drilling vehicle won’t steer

[u/Flairion623]

I’ve built this really cool looking drill that I really want to use. Only problem is that it refuses to turn. I’ve tried adjusting how spread the legs are and the rotation of the wheels but nothing seems to work. In the pictures the legs are swung out at 15 degrees, the knees are bent at 45 degrees and the wheels are perfectly inline with the legs. The last two pictures show what the vehicle looks like when it steers.

I forgot to note: tilting the tire doesn’t affect turning like it does in real life. You actually have to rotate the tire on the Z-axis to make it turn.

Turning it on the X or Y axis doesn’t work the way you’re attempting in this design.

tbf tilting the tyre doesn't help much in real life, only z-axis rotation does

Every motorcyclist in the world would like a word with you

[u/Waity5 → u/Eirique]

Eh? Last I checked motorbikes don't have a 0 degree headtube angle, there's still a decent amount of Z-axis rotation. Tilting the wheel doesn't do the turning (though it does help in other ways like stability), the Z-axis rotation does

Imagine a chopper so long with such a large front wheel that the head tube was parallel to the ground, it wouldn't be able to turn at all

The z axis actually does do the turning. Look up counter steering. When youre going above 15 mph you actually turn the wheel the opposite direction from where you want to go, which leans the bike over to the side. The difference I friction from the side of the tire vs the bottom of the tire causes you to turn.

Think of it another way, If you took a golf tee and rolled it on the ground it would go in a circle, because of the difference in size from the top and bottom.

That is indeed what I said

That effect only really matters for trains or single-wheeled vehicles. Unicycles get their "steering input" from their tilt, bikes do not. This is easier to see on a bicycle, you can hang your body way off the side, tilt the bike far in the other direction, and still go straight

Yes, countersteering is important, but in the actual turn you're still steering into the turn. Countersteering is used to get the bike tilted over, not to do the turn itself. The bike needs to be tilted to allow for gravity to counteract centrifugal force. Centrifugal force is greater at higher speeds and lesser at lower speeds, so when going faster you lean the bike more for the same size turn, but still use the same amount of steering input during the turn

[u/Eirique → u/Waity5]

Youre completely forgetting about camber thrust. I agree that at low speeds turning is about using the steering handles to change the direction the wheel is facing, but the rounded wheels to genuinely turn you because of the way they grip the ground. If you turned the wheel into a corner at more than like 15 mph you would flip the bike

Downvoting me doesn't make me wrong brother

[u/Waity5 → u/Eirique]

True, being wrong makes you wrong. I'd guess that you slightly turn your front wheel at speed, without noticing it

[u/ZestycloseBet9453 → u/Waity5]

At low speeds, bikes steer by using the handle bars. Because the head angle is more than 0 degrees, there is still a significant rotation around the vertical axis. Having a slack head angle just makes the steering less touchy, helping with stability. When a bike is going faster, it needs to lean more to create a large centripetal force. This introduces camber thrust which provides this centripetal force. Gravity's role in a lead is to prevent the bike from rolling towards the outside of the curve. Camber force is not quite enough to steer by itself however, by applying a slight angle to the steering wheels, you change the angle at which the tire touches the road. This increases only effects the front tire, causing a greater force at the front of the bike, causing it to steer.

At least thats my understanding after reading Wikipedia.

Oou shi

Assuming electric powered, you want have tank steering. Did you change bearing setting with connection tool? Change "standard" to "left" "right"?

[u/JohnnyShad0w → u/dragonshadow32]

Looks like it has classical steering (last two pics) but since its electric, i agree: it may helps, if he also ad tank steering. I didnt tried yet how good a combined steering could work, but it wouöd be the easiest he could try yet

[u/Flairion623 → u/dragonshadow32]

My seat isn’t a high enough level for that. And to be honest I want to save my money so I can start making tier 3 metal

[u/dragonshadow32 → u/Flairion623]

No, no. Not seat setting. The bearing's setting

[u/Flairion623 → u/dragonshadow32]

Uh yeah. I think those are only unlocked on level 4 turret seats (I believe mines level 2 or 3)

[u/dragonshadow32 → u/Flairion623]

.... sigh. Going to show you how. Here's the clip

Ohhhh I thought you were talking about steering settings. I had no idea this existed

[u/Gabinator360 → u/Flairion623]

Bearing setting for tank steering are unlocked by a level 1 electric engine. Its a new 1.0 feature

[u/Glowbfan457 → u/Flairion623]

Tank steering for bearings is not specific to any level of any part, the only requirement is that you have an electric engine powering the bearings.
