Trains can transport cargo to many places. Keeping infrastructure like train tracks in good condition is important to ensure trains reach their destinations.

Score
- If the train track is repaired so that it rests completely down/west: 20
- If the train has reached its destination, latched at the end of the tracks: 20
FLLCasts Tip
The easiest way to solve this mission is to complete it by going to the field twice. The first time the robot should have an attachment with a hook to pull / 'push at an angle' the upright rail so that it falls into place. The second time the robot should have an attachment that pushes the rear wagon (through an axle or beam protruding to the left of the robot) until the train stops at the end of the rails where the train is going to be locked. This attachment can be part of the attachment that solves M10.

FIRST LEGO League 2021-2022 Cargo Connect solutions and review with LEGO Education SPIKE Prime
In this course, we demonstrate and explain example solutions for the FIRST LEGO League 2021-2022 Cargo Connect competition. Just like every year, we share solutions only after the season is over. In this course, you will find examples and principles of building attachments and will learn how to program consistent and reliable robots for each mission. You can follow the course, and as you go through each mission, try to replicate the solutions to understand the programs and explanations. Upon completion of the course, you will have many new ideas about how to approach the missions in every FLL robotics competition and how to help your team score more points.
Before starting this course, we suggest you go through the FIRST LEGO League robot game guide

M09. Train Tracks - 100% consistent behavior with more sensors
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.

M09. Train tracks - a two-part mission where only the first part uses sensors
"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.
