Today we're back in Gearblocks with ackermann geometry! In the last video we worked on some front geometry but today we're going to dive into specific ackermann angles and how they change the steering ability of a car.

What part of the car should we work on next in Gearblocks?

Suspension and more weight on the car

You should try and do a type of hydraulics/low rider maybe, a sort of independent ride height P.S. with suspension in line

For the inverted you need yo lower the turn angle down so the outside wheel don't plow the turn you want the wheel no more then 45 degrees or it will slide out and understeer perfect 45 and you will have peek grip at high speeds

@Grunk-ik9os 4 ай бұрын

Also I feel like some weight over the front wheels would help.

@cuberznl 4 ай бұрын

tbh with the anti ackermann probably the reason you liked it at the beginning was because of the sharper turn radius because you changed every part of the steering geometry at once

@timehunter9467 4 ай бұрын

It would be interesting to see a “virtual pivot” for steering where there would be almost zero scrub radius, that would make the Ackerman geometry even more accurate. Having adjustable castor angle would be cool when it comes to suspension.

@danielstarr2483 4 ай бұрын

Anti-Ackermann is used in F1 specifically because of the slip angles in the tires being dependent on the loads. Layman terms: Tires don't go perfectly straight, and how straight they go depends on the weight applied, and the lateral force. With F1, the outside tires in a turn are loaded much more than the inside tires, so they can actually handle more lateral force due to friction increasing with more downforce/weight.

F1 also slips to heat up the front wheels

In the real world, you can drive a rear tire in the ground or lift it on a corner all from the front angles done. That can also be done from power to the drive line in a straight line, or in a corner with a panhard bar or rod, and 4 link setup if done the proper way in the rear. A proper rear setup, can make the front turn better, and harder by force from the rear. What a concept to have, if one spends the time and knows chassis physics. Thank's for the content KAN.

I am so glad I watched the first five minutes before commenting. I felt like I was the only one who knew about the forces involved with performance driving and why you might NOT want perfect 100% Ackerman (where the two lines intersect at the center of the rear axle) for any given car build. Also, in all of my research, it seems even modern road cars don't use that 100% Ackerman number. Lastly, the angle of your tie rods, and by extension, the placement of your steering rack fore/aft on the chassis, also affects Ackerman. I've seen setups (on RC cars, at least) where the knuckles look like they have extreme Ackerman, but because the tie rods are angled towards the front axle centerline (IE your rack would be moved heavily forward) it seems to cancel it out and give them fairly tame Ackerman until full lock.

@Madnessnunky 4 ай бұрын

One of the major considerations for Ackerman steering is the length of the chassis. Your example is almost a limo with how long it is. Ackerman geometry (in simple terms) should have the pivots lined up with the center of the rear driveshaft/axle line between the wheels. (Like a V-shape from the center of the rear.) I'd like to see some level of calculation made to approximate the ideal rear end distance based on your first/best iteration of Ackerman implementation. Given this game is block-based, calculating the proper distance should be pretty simple with grid paper or a digital equivalent. After that, suspension should most definitely appear.

@nidodson 4 ай бұрын

It's actually a real effect that happens that race teams have to take into consideration for their setup, as the weight of the car slightly shifts to one side when the engine is reved up higher. So, the problem with his physics engine is that it is too pronounced. Pretty cool thing we normally never think about.

I kinda want you to get The Unofficial Lego Technic Builders Guide Second Edition, it shows and explains a lot of mechanisms that you might find interesting, and explains how to find the correct Ackerman geometry. It is 6 years outdated in terms of Lego parts, but that doesn’t affect the mechanisms.

@calebs4887 4 ай бұрын

I once had to implement the math for ackermann steering (essentially create the geometry virtually, which spat out the right and left wheel angles to a pair of servos), and it was such a struggle to get all the math correct and working properly. Getting the equations in the right order was such a PITA that I broke down and used chatGPT for the first (and only) time.

Gearblocks would be the perfect game to implement the Engine Simulator that AngeTheGreat made for powering the piston engines.

Look at the setting for the tires, you can change both the driving and sliding friction

@MattDvc 4 ай бұрын

Build a chassis, add batteries to give it some good weight, balance it, put brakes on all four corners, adjust the braking force on the front so they on the edge of locking, adjust rear brakes so they wont lock but still have decent breaking power. Then start playing with suspension and geometry. You won't be disappointed, 👌

You should also try and make a fan car using the propellers to provide downforce so you can make the car as fast as possible. With my design I was able to get sub 25 seconds on the inner loop

Try using thicker wheels, so you have more surface area in contact with the ground, which translates to better grip.

@jonahgetz5882 4 ай бұрын

3:40 Kind of? Technically speaking any wheel that is supplying a lateral force will develop a slip angle as the sidewalls deform from the load. F1 has large lateral forces and tall sidewalls, so this slip angle (the angle between the direction that the tire is pointing and the direction the tire is moving) is very large. Because of this they make sure that the point the wheels line up to make a circle *after the slip angle is accounted for* and in order to make the tires line up at the contact patch you happen to need a slight anti-Ackerman at the kingpin in F1. Although that really gets into the weeds about the road-tire interaction, and this video game may or may not reflect reality depending on the physics modeling they're using.

@taimurahmedrafe4984 Ай бұрын

Man, pls do anti ackerman with a bit less steering angle in general, the front wheels were almost perpendicular, if it had normal-ish steering angle it would perform much better

@stratch1559 4 ай бұрын

Once suspension has been added and upgraded I would like to see a faster transmission, potentially two electric motors powering the vehicle.

@willie9899 4 ай бұрын

I wonder if powering the front wheels would help with the front end plowing

@roccov3614 4 ай бұрын

I think you spin out because you lose traction with your back wheels before losing traction with your front. The reverse ackermann made you lose traction with your front wheels before the back wheels. That probably explains why you spun out less. Maybe the perfect set up is to have the ackermann angle set so the front wheels just barely loses traction before the back ones but not so bad that you can't steer.

@SabertoothTamer 4 ай бұрын

For the Anti-Ackermann it might turn better if you used a controller so that you don't largely oversteer.
