This page shows all the robotics tutorials listed without specific grouping. Each tutorial is short, on specific topic, has a video. Tutorials are structured in sequence in Courses.
On of the most precise ways to position on the FIRST LEGO League and other competition fields is to follow and align and in this tutorial we demonstrate exactly this - how consistent and reliable this method is to reach specific mission models. In this way you know that every time you will be at the right place, which is great.
In this video tutorial we show how you can build robots that position on the field consistently and reliably by following and line and then aligning to a line. We also demonstrate the concept of "double align" which is quite powerful and even if there were some mistakes they will be handled.
This tutorial demonstrates how a robot could align to a black line. The code for the program is available in the course. Aligning to black lines is popular at robotics competitions like FIRST LEGO League as it is the primary way to know where you are on the field and to develop a program that is reproducible. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
In this video we are showing how to use two light sensors to do basic aligning on a black line. This is always needed at the competitions. We also show an example for following a line with two sensors.
