We want you to know how things work, so that you should make some adjustments to the block.

How that block works
Open the myBlock in the software and follow the text below. A picture is intentionally omitted here.
There are three important things to remember for the time being. The myBlock uses a yellow block for color sensor and reads the color in front of the robot.
After that, the myBlock calculates where the robot should steer. We use these calculations "as is", we don't change them.
Finally, the calculated result is used to control the steering motor of the robot.
What needs to be adjusted
The yellow block for color sensor must match the port of the sensor on your robot.
The last two blocks must match the port of the steering medium motor of the robot. Both the yellow rotation sensor block and the green motor block must be set to one and the same port.
If the robot is still not following the line well
Think of the speed and the direction of the robot. In Level D2 we discussed and practiced what the correct direction of the robot should be and what maximum speed it could use.

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.
