When the EV3 color sensor is exactly on the black line, it's value is 4. When I start moving it slowly towards the white space, the value is getting greater and greater until we reach a value of 39 to 40. Again, our aim will be to follow the line between the black line. The latest version of the Line Follower lesson is available at thiswebpage while the latest version of the Wall Follower lesson is available at thiswebpage. Our LEGO EV3 Line Follower robot follows the black line that has several curved turns and may split and re-join. It uses the 2 LEGO Large motors in reversed position with big LEGO wheels. The robot can also cope with track obstacles like objects laid on the track or line cut-offs. Refer to the Robot Design page on this site for various base models that can be used with our lessons. If you are using an EV3, we recommend that you start with EV3 Enterprise, EV3 Discovery, DroidBot 2,0 or the base robot in the EV3 Education Core Set.
Proportional Line Following with EV3 Mindstorms. Part 1 In this first part we stop at an algorithm that is the base for following lines and explains the basic idea for the proportion. A must watch if you want to understand the robot at its behaviour. A PID Controller For Lego Mindstorms Robots. A PID Controller is a common technique used to control a wide variety of machinery including vehicles, robots and even rockets. The complete mathematical description of a PID Controller is fairly complex but a much simpler understanding is really all that is needed to use a PID effectively. Proportional Line Following with EV3 Mindstorms. Part 2. Proportional Smooth Line Following. Use this program and you won't have problems in following lines with EV3 Mindstorms Color Sensor: English. This is the result that we currently have for the proportional following of a line.
This Line Follower robot is designed to have almost all of its weight over the drive wheels. Using a small scale in the experiment shown below, we find that the robot weights a total of 622 grams, with 560 grams over the back wheels.
