WRO Robot building instruction
For World Robotics Olympiad Ball Collection competitions we prepared an interesting Robot Base Chassis that could be extended with a container. The container contains the ping-pong ball. A mechanism collects them. This LEGO Mindstorms EV3 building instructions are for the chassis of the robot and were one of the versions from a series of robots.

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.

Example program for using the Advanced Calibration Blocks Package
This is the example program using the blocks available at Blocks Package for Advance Calibration of LEGO Mindstorms EV3 Color/Light sensors. The program makes the robot find the minimum and maximum values and to calibrate the current sensor value depending to the min and max.

PLF-block with two coefficients
EV3 PLF-block for LEGO front-wheel steered robots. The block has two relaxation coefficients – one for steering to the left and one for steering to the right. The aim is to make the robot follow a line smoothly when the color sensor is positioned closer to one of the wheels.
The block has the following parameters from left to right:
- Maximum angle – the maximum steering angle of the front wheels.
- Relaxation coefficient left – the relaxation coefficient regulates how sharply the robot responds to error, turning left. The default value is 1.
- Relaxation coefficient right – the relaxation coefficient regulates how sharply the robot responds to error, turning right. The default value is 1.
- Value on black – the value detected by the light sensor when it is on the line.
- Value on white – the value detected by the light sensor when it is outside the line.

Initialize an array for Advanced Light/Color sensors calibration
"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must.
In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block
