How can I navigate the car with Neo 6m gps with my RPI-4 model-B. I'm receiving the data from gps correctly but how can I get the turn angle form gps data to rotate the steering to get the directions. I have placed a dc motor and motor driver on the steering of car to rotate the steering. but I'm unable to find the way how much I have to rotate the motor using that gps data.

Note: The car will run on constant speed and plane road. The purpose is only to auto-steer the car using the gps data

The Component I already have:

  1. Raspberry pi - 4
  2. Dc motor
  3. Motor driver(bts6760)
  4. Ultra sonic distance sensor

Any other component needed for this?

thanks

One method to achieve this is to use the pynmea2 library to parse the GPS position and get the true_course (the direction the car is heading). Then use the pure pursuit algorithm to work which way your car needs to turn to achieve its desired waypoint.
