• Run on rails

This is a 10 out of 10 tutorial in which the Minibox accomplishes M08, M14, and M15 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge robotics competition. The robot is a LEGO Education SPIKE Prime box robot. In this run, the robot should consistently and reliably deliver the LEGO minifigure to its designated place and then push the M08 camera down the track to shoot the movie scene.

In this video tutorial, we demonstrate how to accomplish the second part of M8 of the the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot built from LEGO Education SPIKE Prime.

The goal of the mission is to push the M08 rolling camera up the rails. Let's see how the robot does it.

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.

"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.

Getting a camera into exactly the right position to capture a shot requires a lot of precise movement and great communication with the actors.

Release the camera down the track to shoot the movie scene.
