How to forward align to a line with two Color Sensors from LEGO Education SPIKE Prime
The reason why you would want to watch this tutorial is because it demonstrates one of the most reliable ways to know where you are on the field and to accomplish missions successfully and this is aligning to a line. In the tutorial you will also see how a parallel program is developed and who parallel programs could be used in a meaningful way.

FLL 2021: Use of motion and color sensors for a three-part mission - How to accomplish the Train Tracks mission
This tutorial explains the use of motion and light/color sensors to accomplish a complex mission split into three parts. It gets into detail about how we keep a straight line with the motion sensor, follow a line with the color sensors, and transition between different parts of the program by aligning and detecting lines with the sensor. The goal is to get to a reliable and consistent behavior of the robot. On top of that, it is configurable, as we've left a few parameters that could be set to configure the behavior for a specific robot, venue, lighting, battery level, and wheels friction.

Crossed lines (T Sections). Positioning. Part 1.
How do you detect a cross-section and move from following the main line to following the crossing line. In this series of video tutorials we are starting with a very simple solution that could work in most of the cases. It is especially useful for the FIRST LEGO League Trash Trek competition where there is such a section.

How to Solve Senior Solutions Medicines, Cardiovascular and Strength exercise missions with one attachment
In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab.

How to arrive at a specific position on the FLL field with LEGO Education SPIKE Prime
This is one of the last tutorials in the LEGO Education SPIKE Prime programming for Competitions course and it demonstrates what we've all been waiting for - how to reach a mission model from base in a reliable and consistent way when the mission model is on the other end of the field. Naturally what we use are all the different concepts that we've learned in the course and the tutorial is more advanced than the other so if anything is not clear take a look also at the different tutorials an concepts in the course.

FLL 2021: 10 out of 10 on how to accomplish The Bridge mission
This is a 10 out of 10 video tutorial where we demonstrate the consistency and reliability of a LEGO Education SPIKE Prime Active attachment connected to the motors of the robot. The goal of this attachment is to accomplish the Bridge mission where we have to push both parts of the bridge and bring them down to connect them. We use some line following.

10 out of 10 on arriving at a specific position on the FLL field with LEGO Education SPIKE Prime
Using everything that we've learned about LEGO Education SPIKE Prime competition programming we arrive at the final boss mission - how do we consistently reach a mission model at the other end of the field. Consistently. Every time. We use line following, motion sensor, counting of lines and border alignment. All the different concepts that we've looked at separately are now implemented together.
