Methane Loops and Truck. FIRST LEGO League Trash Trek 2015
There are many loops in the FIRST LEGO League competition. In this video we collect some of them by following the idea of the ELM team.

There are many loops in the FIRST LEGO League competition. In this video we collect some of them by following the idea of the ELM team.
Many FLL competitions have a mission for demolition. You should always destroy something, but destroy it in a regulated manner and probably collect the destroyed mission model after that.
Here is Iknathir - a LEGO Paper Plane Launcher. Just take a piece of paper, fold it to create a paper plane, place it on top of Iknathir, press the lever forward and the plane will be launched in the air. If you are not sure how to make a paper place, we got you covered! Just go to the following tutorial - How to make a simple paper plane. Feel free to experiment with the structure of the plane. How far can your plane go?
This tutorial is about how to follow a wall with an ultrasonic sensor. The example is with a border from a FIRST LEGO League (FLL) competition, but could also easily be applied to other competitions and problems.
We keep the robot orientation straight while moving, but when we stop the robot could be in a different orientation. This applies for both using the Mindstorms Gyro Sensor when moving straight or the Mindstorms Color sensor when following a line. In this video tutorial, we will do a few examples of when an how this could happen.
This is the final run for our World Robotics Olympiad (WRO) 2015 Elementary Challenge Robot. In "dives", detects the color of the pearl and then counts the number of Ping-Pong balls to release.
You can collect the car for scrap or repair it. The ELM teams decide to repair it. This requires them to place the engine in the car and it's very interesting to think about this problem.
We've detected the gap. It's time to move over it. This is difficult because we have to detect where the line is after the 0.1 meters gap on the line following field.
In this tutorial we would should you how to accomplish the FIRST LEGO League 2019-2020 Mission called Elevator. We are using the Whakatae - LEGO Education SPIKE Prime Competition Box robot
We create a program for detecting when the Touch Sensor was Pressed/Released. Move until it is pressed, continue when it is released.
In the first LEGO tutorial we started following a wall with the Ultrasonic Sensor. In this tutorial we would improve the program, remove the zig zag movement and make it very smooth.
The way sensors and programs work in a robotics system is sometimes not-intuitive for a beginner, but nevertheless very logical. Building a program for a touch sensors for "Press->Go->Press->Stop" using the EV3-G software could be quite challenging at the beginning even for experienced teachers, students and robot builders.
This is a fun video with robots doing the Harlem Shake. We thought about posting the programs for the robots, but actually the whole Harlem Shake is so awkward that we decided not to do it :) Enjoy the video
Scratch is a very good platform for you to start learning to program. Here's how you can start and what you need to know for your initial orientation.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We would be making mistakes, showing them and taking up the challenges right in front of your eyes. The first construction would not be perfect but we would eventually arive at it.
"What is the light in the room?" - should it even matter. You can use one program for all lighting conditions by calibrating the color/light sensor of the LEGO Mindstorms EV3/NXT robots.
Tasks for school STEM classes or home exersie. Try to solve them to submit your solutions below.
One attachment to rule them all...We have seen it and it works -> solving most of the competition models with only one attachment. In this video tutorial without programming we would walk you through the principles and methods of using a single attachment for most of the FIRST LEGO League competition models. One can learn alot from using as few parts as possible to solve as many missions as possible.
Mantissa, a LEGO Mindstorms Robot, moves and attacks. It uses the ultrasonic sensor and it's two special hands. Follow the building instructions and download the prepared program to directly use the robot.
Specific challenge on programming the robot to move as a Yo-Yo
Experiment with moving the robot in different geometrical figures. The tasks could be used in STEM classes for introducing students to geometry and math.
Lifting a loop is one of the most common missions in different robotics competitions. In this video we demonstrate how we could do "Vertical lift". It is suitable for precise lifting especially when the mission model requires you to lift straight up. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
In this tutorial of the series we would get into more details on how the flywheel works, what's its purpose and how the whole attachment is triggered with the first rubber band.
"The devil is in the details". We are improving the Rubber band attachment with a Flywheel by introducing a few small, but important modifications that make the whole robot attachment more stable and reliable. With the conclusion of the series this attachment could be used as a basis for some very interesting STEM demonstrations on energy accumulation and conservation.
Move the robot using the Move Steering block. We explore what the different values for Steering mean and how to use them. We also explore how the motor is configured to run for a number of rotations or seconds and what is the difference.
How to search for an unknown value with the fewest possible tries.
