4 wheeled differential wheeled (skid-steer) robot steering problem

My question is about a square shaped differential wheeled robot, I built, that has a hub-motor (BLDC motor) attached to each corner, i.e., the wheels on the same side, either left or right, have the ...

How to determine the required CPU speed for a micro-controller with a 2-phase encoder attached to interrupts?

I am building a high-torque steering servo. I am trying to use the Adafruit Feather M0, which has a CPU speed of 48MHz, to monitor a 2-phase encoder that has 2400 pulses per rotation. I have attached ...

Tuning PID controlling car's steering angle

We built a car model with Ackerman steering type for line following task. The distance between rear and front wheels' axes was about 42 cm. Then we tuned PID controller (really just PD: Kp = 0.9, Ki = ...

Overcoming or managing dead time in vehicle steering controller

I found out there is a dead time in my steering controller after several runs. The transfer function for it in the $s$-domain is: $$ H(s)=\frac{270 \cdot e^{-0.03s}}{0.015 \cdot s + 1} $$ To ...
