Video tutorials

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. 

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.

Very simple and basic introduction to the color sensor in the LEGO Mindstorms EV3 set. The first program is to stop at a line. Then we can move from stoping at line to counting lines and even more complex tasks.

Tasks for school STEM classes or home exersie. Try to solve them to submit your solutions below.

Previously we caught the Truck with two rubber bands. The next step was to lift it. For lifting we used the Medium LEGO Mindstorms EV3 motors. In this video we are extending the attachment so that we could catch also the Ambulance. In forth video we would explore how to release both vehicles after transporting them.

"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.

Follow an object using the LEGO Mindstorms Ultrasonic Sensor. Object moves away, the robot moves with the object. The program is very useful if you are doing STEM classes and you want to demonstrate results. People react very well to a robot following you like a dog for example. 

Stop on detecting an object with the Ultrasonic sensor and move after detecting there is no object. Join of the previous two video tutorials in one

The robot detects an object. After the object is remove we want to make the LEGO robot move forward.

We are introducing the LEGO Mindstorms EV3 Ultrasonic Sensor. The first program is actually to detect an object and stop near it, at about 4 inches/10 centimeters. The ultrasonic sensor could be used during robotics competitions, but most of its use is for experiments.

Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down. 

Tasks for STEM classroom and home exercise to get you used to using the LEGO Mindstorms Touch sensor.  Solve them, build a program, record a video and upload your solutions below. 

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.

We create a program for detecting when the Touch Sensor was Pressed/Released. Move until it is pressed, continue when it is released.

Complete introduction to the LEGO Mindstorms EV3 Touch sensors from the very first step. In this video tutorial we program the robot to stop on touch sensor pressed. Again, this is based on your feedback that much of our tutorials in previous years were a little more advanced and that we have never made a proper introduction. A few more videos on touch sensor will follow after this

One of the most interesting challenges in the series of FLL Competitions. Move a block and add additional floor on top of the block without damaging the construction. In this tutorial we would focus only this mission and we would achieve two movements with only one motor which makes the attachment quite powerful.

Robot tasks to exercize how to position on the field using only motors. STEM classes could use it to demonstrate mechanical imperfections in constructions and how important using sensors in this LEGO Mindstorms Robotics sets is 

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. 

Experiment with moving the robot in different geometrical figures. The tasks could be used in STEM classes for introducing students to geometry and math. 

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. 

First time programming the motors of the robot using the EV3-G software installed on a computer. We would explore how to move forward/backward and turn with the robot.

The LEGO EV3 Mindstorms brick can be programmed from the brick itself. The motors can be moved forward/backward and even simple programs could be implemented without even touching the EV3-G software at the computer

Tasks for introduction on building robots.

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

With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor. 

The attachment is now so advanced that we can do two tasks at once with it in order to solve the FIRST LEGO League 2014 World Class Search Engine Mission.

The third part of the series the goal is to extend the robot attachment so that we could solve the second part of the FIRST LEGO League World Class mission challenge - to take the loop.
