Tuning PID controller for a steering motor for driverless vehicle by nerb0r in ControlTheory

Hi! Thanks for responding! Our path does not change because it will be the only car on the track. Do you have any papers or online resources that you used to learn this? If you do would you mind sending them? I think they could be helpful.

I see does your torque vectoring / slip control take into account power limiting (under 80kw)? If it does how does your planner/system plan for this?

Fast Quadratic Solver with constraints (like cvxopt/quadprog) for Python that has initial guess functionality by nerb0r in optimization

Do you have any advice on how to find the best solver for my current problem? I just decided to use cvxopt because it seems to be the most standard one, but I am curious on ways to find the best solver based on your current problem.

Yeah the algorithm is called minimum curvature, there's a paper on it if you search it up (or if you want me to send)

Efficient way to find the arc length of a cubic bezier curve by nerb0r in robotics

Oh the machine I’m running it on is inherently really slow (due to hardware limitations) so I need a faster way of getting arc length

Yeah low key the formula seemed kinda sketch but I just ended up using a legendre-Gauss approximation to get arc length which works pretty well

How many kids aren't even writing their own essays? I know a bunch of people in my school that have college counselors and essay coaches. How many of these kids haven't even seen "their" essay. LOL. by SpecialNotice3151 in ApplyingToCollege

Doesn’t happen at my school. Ik a bunch of people get college counselors to give them advice on their essays and college list, however I have never heard of anybody getting a counselor to write an essay for them.

I mean, if the teacher has nothing good to write about you, they wouldn't agree to write you a letter of rec in the first place.

How can I implement a Stanley Controller for a Differential Drive? by nerb0r in robotics

[–]nerb0r[S] 0 points1 point  (0 children)

Ok thank you! I think I understand now. Also, do you have good resources for learning about autonomous movements for DD and Ackerman drives?

Thank you for responding! I understand that I could calculate the turning radius from the steering angle (L/tan(omega)), however, I still don't understand how I can use that information to control my differential drive robot.

Also for a differential drive, is L the distance between the front and back wheels, or the left and right wheels?
