Create your post! thanks in advance. For tuning, I always go with "Trial and Error".Start with low Kp (for example Kp = 0.2) and keep increasing it by any increment steps you want (for example keep increasing it by 0.1 each time you try) until you reach your desired performance. Going back to the lane keeping car, my controlled variable was throttling speed (since steering has only two states either right or left). Zheng Wang from Bridgwater State University has used a Raspberry Pi and some other hardware to modify a remote-controlled (RC) car to follow a track, detect, understand and respond to stop signs and traffic lights, and to avoid collisions. If your motors draw a lot of current and can not be connected to one motor driver, then connect your 4 motors to 2 motor drivers and control each one individually.As for the code:- If you choose to connect two motors to the same output use:Right_motor_PWM = constant_throttle - PID_outLeft_motor_PWM = constant_throttle + PID_out- If you choose to control each motor individually:Front_Right_motor_PWM = constant_throttle - PID_outRear_Right_motor_PWM = constant_throttle - PID_outFront_Left_motor_PWM = constant_throttle + PID_outRear_Left_motor_PWM = constant_throttle + PID_out, Question As mentioned earlier, if steering angle is greater than 90, the car should turn right otherwise it should turn left. 2. I got mine from. (error increases, P action also increases). Two client programs run on Raspberry Pi for streaming color video and ultrasonic sensor data to the computer via local Wi-Fi connection. Best of luck! 8 months ago. Part-1: (Course - 1) 1. The error is calculated (error = setpoint - actual). Full disclosure: This car is perhaps not quite as big as the car you envisioned when you read the headline.
