PLF-block for steering robots

The block has the following parameters from left to right:

Maximum angle – the maximum steering angle of the front wheels. It is measured from position of straight wheels, to maximum left or right position.
Relaxation coefficient – the relaxation coefficient regulates how smoothly the robot follows the line. The default value is 1. In general the range for the coefficient is between 0.5 till 2. If the difference between the value measured by the sensor on black and on white is great i.e. on black is 10 and on white is 80, then the coefficient should be smaller. If those values are closer, then the coefficient should be larger.
Value on black – the value detected by the light sensor in reflected light mode when it is on the line.
Value on white – the value detected by the light sensor in reflected light mode when it is outside the line.

This Program is used in the following courses and lessons

Instructors Remote Training

If you are working with students and you want to introduce Robotics to your class or you want to mentor a FLL team, but you are insecure about your technical knowledge in the Robotics field, then this is the right place for you. Having in mind teachers' busy schedule, we have design two different schedules and added an option to design one just for you. FLLCasts's Mindstorms EV3 Robotics Online Training is the perfect match for any teacher.

After the completion of each task the participant has to upload his solution for verification.

My Blocks

In this section we will learn how to create, edit, import and use My blocks. First we begin with ilustrating a use of My blocks. There is a whole group of robot constructions called steering robots. Today we will build a steering robot and learn more about the way it is driven through a differential. Then you will have to download a My block that implements the Proportional Line Following algorithm for steering robtos. You need to download, import and modify the block to fit your robot setup. Finally, you will have to create a block of your own and learn how to add parameters.
