Car Follower

Synopsis

An Ev3Dev program that allows the Ev3 to acccurately follow another RC car infront of it using proportionality.

Tutorial

1. Clone the repository.

2. Build your robot. Make sure that the robot includes two large motors, an ultrasound sensor, and a touch sensor .

3. In lines 47, remove the negative sign in left_motor.duty_cycle_sp = int(-(power + correction)), right before the word power. Do the same for line 48. I have the negative sign because my robot's motors are reversed.

4. Run the program! Change the constant of proportionality, power, and target distance by changing the variables kp, power, and target in line 21.
