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.

PLF-block for steering robots
The block has the following parameters from left to right:
- Maximum angle – the maximum steering angle of the front wheels. It is measured from position of straight wheels, to maximum left or right position.
- Relaxation coefficient – the relaxation coefficient regulates how smoothly the robot follows the line. The default value is 1. In general the range for the coefficient is between 0.5 till 2. If the difference between the value measured by the sensor on black and on white is great i.e. on black is 10 and on white is 80, then the coefficient should be smaller. If those values are closer, then the coefficient should be larger.
- Value on black – the value detected by the light sensor in reflected light mode when it is on the line.
- Value on white – the value detected by the light sensor in reflected light mode when it is outside the line.

Sumo Competition Robot from LEGO Mindstorms EV3
This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.
Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring.

WRO Robot LEGO Base for container attachment
LEGO Mindstorms Robot Base for a high placed attachment for containing ping pong balls. It is interesting how the balance is achieved with such an attachment. It was only one of the version in a series of LEGO Mindstorms Robots for World Robotics Olympiad.

WRO Robot with a Ping Pong Balls Collecting Attachment - Full
This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.

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.
