This seems unnecessarily complex. If the whole point is that two front tires don't have the same angle when turned, you could start with the math and be done in a minute, or leave it out and do it all with shapes and then describe the simple fact that the wheelbase divided by the radius (at any given degree of steering) is the angle of that wheel – and be done in half a minute. But, you left nothing out.
Why is that so many videos (and books) which explain stuff spend 80% of the time talking basic concepts and only spend 20% of the time talking about the advanced concepts?
Excellent
Good starter video
Too complex, not needed. Best is to use few but correct words and drawings.
First video I've seen that clearly explains the math behind Ackermann steering, instead of just what it is mechanically. I was looking precisely for this, so thank you!
can you explain anti ackerman too?
so the ideal set up is delta delta i and delta o should be as near as possible to each other? ( have a modified off road vehicle that is all over the place as i drive)
Before calculating the tire-angles, don't you need to calculate the radius of the front-tire first?
Can you make a video on Front Steer vs Rear steer,
what should be the Ackerman percentage for off-road cars?
What about the radius of the curvature path of the ideal tire, it should be slightly bigger then the radius of the rear tire, but you didn't show how to derive it…
wow
This is the best example of Achermann's Geometry that I have seen. Great job!
Great video! I have a question, how should ackermann be approached when most of the steering input is counter steering to the right when making a left turn such as on a dirt surface? Thanks
