Video tutorials

Based on your feedback we've build a course for introducing new students to the LEGO Mindstorms EV3 programming and construction. It is designed for school groups, competition teams and students alone in home that can get our feedback on their progress

This tutorial in an animated demonstration of how a LEGO Education SPIKE Prime robot turns to the left and to the right. To download the program check out the courses in which the tutorial is used.

Counting lines and stopping on the third is the subject of this video. It is important to know how to do this in order to conduct more than one experiment in STEM classes (if we consider that each line is an experiment)

The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands. 

Recap on the attachments, their purpose and how you should use them. 

This video is about a lever that should be pushed and this lever is connected to an axle. This means the lever should rotate. It is a common mission on robotics competitions like FIRST LEGO League/World Robotics Olympiad. The inspiration for this mission is the FLL 2012 Senior Solutions Oven mission. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

This tutorial demonstrates how a robot moves forward in a straight line with the use of the LEGO Education SPIKE Prime Motion sensor. While the robot is moving we push on the robot at the back, simulating that "something has happened" and the robot then again returns back to the moving straight. To download the program check out the courses in which the tutorial is used.

In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition. 

The program from part 3 should be refactored and improved to make it easier to understand and support. We extract most of the repeatable behaviours in a loop and this reduces the size of the program three times in terms of the number of blocks used. 

This video tutorial reviews the EV3 Gyro Sensor and the HiTechnic Gyro Sensor for the LEGO Mindstorms NXT robotics Kit. We compare the two sensors and demonstrate them in action.

In this video we are showing how to use two light sensors to do basic aligning on a black line. This is always needed at the competitions. We also show an example for following a line with two sensors. 

In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.

This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.

Tasks for introduction on building robots.

Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set. 

In this video tutorial we will show you three ways for making your robot stable on the field. We will present each one of them with their advantages and disadvantages - it's up to you to choose which one is the best for your case.

Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons. 

The way you move the robot is always imprecise. Don't TRY to fight with this. Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind. 

This one is very special- an attachment that could lock itself on purpose while working. 

The color sensors supports different modes of working. In this video we are working with the Reflected light, which is not actually the detected color. Most robotics sensors actually work with reflected light and you should definitely learn how to use this mode.

Enchansing a previous attachment, but only this time we are solving the FIRST LEGO League 2012 Medicine mission. There is a lever and a rubber band. When the lever is released the rubber band activates the attachment. 

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.
