Light sensors cover on LEGO Mindstorms NXT robots

In this video we are solving one of the most important challenges on the FIRST LEGO League competition, i.e how to cover your Mindstorms NXT light sensors so that they are not affected by outer light sources at the day of the competition. Once again you would find 3 solutions and more will come in the next videos.

A common problem at the competition is that most of the time the light sensors are affected by light sources in the room, in the hall, in the venue, so to make an efficient robot you must find a way to cover the light sources so there is no other light sources that affect the work of the sensors. Today we are going to show you a few ways to cover the light sources on this robot, to cover the light sensors, and in one of the next videos probably we are going to show you in details how to calibrate the sensors and what you can do with the sensors. One of the first ways you can cover the sensors on this construction, on this robot is to use two very simple parts. You can cover it from here. We have come up with another part we could use for covering the sensor, it looks like this. I will probably remove the tier and I will keep it right here. Currently the right sensor is much well covered than the left sensor. We have also come up with another idea to cover sensors, it includes these six parts attached to each other. I will put them right here. And in this way you can cover your light sensors so that they are not affected by the light in the venue.

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

FIRST LEGO League Competition. Constructing and Programming a Robot Base

This course if used by teams, mentors and students to structure the preparation for the Robotics Game of the FIRST LEGO League Robotics Competitions. One thing that is common each year at FLL is that experience matters a lot. Our goal with this course is to quickly bring new teams up to speed with experienced teams and to share some new tricks, patterns, constructions with the more experienced teams.

Simple following and aligning to lines and borders

Before looking at the way we do follow lines first we have to make sure the light/color sensors are covered. The next video is a classic NXT light sensor covering, but it also applies directly to EV3.

FIRST LEGO League with LEGO Education SPIKE Prime. "Challenge" competition for 9-16 years old

This is the most detailed course we've ever built on how to prepare for a FIRST LEGO League robotics competition and we've specifically focused on the use of LEGO Education SPIKE Prime as a simple Box Robot. The course consists of 25 lessons suitable for both beginner and advanced students. We build on the knowledge of 10 years of sharing example solutions with explanations for FIRST LEGO League robotics competitions.

This course is one of the popular courses in the FIRST LEGO League Robot Game. The Complete Guide. We recommend you also check out the whole guide.

Cover for color sensors

FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old

The goal of this course is to take you through some of the most useful principles for building and using attachments to accomplish missions at FIRST LEGO League competitions. The whole course is based on a LEGO MINDSTORMS Robot Inventor and you need a single 51515 set and without additional parts (you will need a second color sensor for the lessons for using two color sensors, but feel free to skip them if you don't have it). For every mission there is a Scratch and Python program attachment. The course consists of 25 lessons suitable for beginner and advanced students. Every lessons consists of a video tutorial demonstrating the principle and how the mission could be accomplished along with building instructions for the robot, the attachment and programs for controlling the robot.

Cover for color sensors

In this video tutorial we demonstrate the importance of properly shielding and protecting the light/color sensors of your LEGO Mindstorms Robot Inventor robots. These principles generally apply for all kind of robots. The problem is that external light sources from the venue could change the behavior of the robot - like have you ever been to a competition venue where the lighting just makes the robot behave in different ways? - well this tutorial is for you!
