EV3 basics course. Gyro Sensor. Turn at an angle (part 1)
The Gyro sensor in LEGO Mindstorms EV3 sets is new for the sets and we answer basic questions about its usage. The sensor detect when the whole constructions turns at a particular angle, but there are a number of gotchas in using it.

EV3 basics course. Gyro Sensor. Why is the robot turning to a different angle (part 2)
Turning with the Gyro Sensor on a specified angle and stopping there have never been easy. It is not going to get any better. However, this is not a problem of the Gyro sensor. The problem is in the way we develop our programs.

Gapped and Crossed Line Following with LEGO Mindstorms. Part 1. Challenge. Use of State Machines
We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.

EV3 basics course. Color Sensor. Detect line (part 1)
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.

EV3 basics course. Color Sensor at a competition (part 7)
In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.

Gapped & Crossed Line Following. Part 2. Strategy
Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot.

EV3 basics course. Color Sensor. Stop on third line. Hack (part 2)
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 is not at the right position at the end of the straight movement?
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.

EV3 basics course. Precise motor programming for competitions (part 7)
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.

EV3 basics course. Ultrasonic Sensor. Detect object (part1)
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.

EV3 basics course. Precise motor programming. Tasks (part 8)
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

How to calibrate more than one LEGO Mindstorms EV3 Light/Color sensors at a time
Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors.
When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.

EV3 basics course. Motors control and program from the brick (part3)
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

EV3 basics course. Programming motor from EV3-G on the computer (part 4)
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.

EV3 basics course. Ultrasonic Sensor. Move after object is removed (part2)
The robot detects an object. After the object is remove we want to make the LEGO robot move forward.

EV3 basics course. Touch sensor (part 1)
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

EV3 basics course. Touch sensor. Non-intuitive, but logical (part 3)
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.
