Demolition. Destroying and Gathering. FIRST LEGO League Trash Trek 2015
Many FLL competitions have a mission for demolition. You should always destroy something, but destroy it in a regulated manner and probably collect the destroyed mission model after that.

Precisely dropping the chicken. FIRST LEGO League Trash Trek 2015
This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.

Pinless attachments. FIRST LEGO League Trash Trek 2015.
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.

WRO Junior-High 2014. Sputnik. Following an orbit. Part 2
We would see how both satellites work together on the World Robotics Olympiad competition. They must both follow different orbits and must cooperate for the mission to be accomplished.

Gapped & Crossed Line Following. Part 11. The state of "Lost"
We discuss the state of "Lost" and the different ways we could escape this state. We also build the next step of our State machine programming pattern where the next state is determined by the previous state.

Best Seed for the longest living seed in a 6x6 field. Robotics Game of Life
The task is to find what the best seed is that will live the longest without entering into a loop or without dying. Find it and submit in the tasks section.

Display 2D Arrays on the bricks screen with a block. Robotics Game of Life
Display a matrix with "life" and "dead" cells on the EV3 LEGO Mindstorms brick screen. The program is available. You can see it, change it, modify it and learn from it.

Display the game on the brick screen. Robotics Game of Life.
Learn to program the Game of Life on the LEGO Mindstorms brick screen. This would require drawing on the brick screen, using blocks with switches and loops.

Gapped & Crossed Line Following. Part 10. Robot is lost
All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.

Programming with one language with code ready. Robotics Game of Life.
The code is already ready. It is attached below the video. Let's see how the program works and what it does and how to use it.

EV3 Robot with Motors in Opposite Directions. Proportional like following. Part 3
Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.

General Programming of the Game. Robotics Game of Life.
In the current course we would use a number of languages. Generally we would program the robots in EV3-G, but we would also program them in JavaScript to make the parallel with the JavaScript. The programming would include arrays, switches and loops.

Simulation online. Robotics Game of Life.
There are a number of tools available online to help you play the game. You just seed the initial conditions and leave the game. Let's look at some of the sites.

Gapped & Crossed Line Following. Part 9. Crossed Sections
We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.

EV3 Robot with Motors in Opposite Directions. The Frankenstein. Part 2
We are programming this strange construction to move in a square. This is a basic task, but it is worth doing for a robot with motors placed in different directions.

Gapped & Crossed Line Following. Part 8. Turn left state
Next state in our state machine programming pattern is the "Turn Left" state and the corresponding behaviour.

Robot Design Ideas for Chassis with Mindstorms EV3. Base Chassis 5
The last fifth construction is larger compared to the previous constructions. It is wider. It has four sensors and you can take a larger load all by keeping the robot stable.

Gapped & Crossed Line Following. Part 6. Move after the Gap
We've detected the gap. It's time to move over it. This is difficult because we have to detect where the line is after the 0.1 meters gap on the line following field.

Robot Design Ideas for Chassis with Mindstorms EV3. Base Chassis 4
Probably the robot I like the most from this series of five robots. See the video to understand why and what is interesting and special about this robot.

Gapped & Crossed Line Following. Part 5. Detect Gap
It's inevitable. While following this gapped line we would reach a gap. The robot must somehow understand that there is a gap and must make a decision on what to do. For detecting the gap we use the Rotation Sensor. Not the most popular, but very convenient in many cases. Check out the video.
