Video tutorials

In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field. 

With the shape of a box it is very easy to align this robot to different wall and to add very stable pinless attachments to it. The goal of the video is to discuss this feature of this particular robot construction.

With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build. 

Where should you lift the robot? Especially if you don`t have the mission model that we are using

Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

Let us do a quick recap of the whole lifting mission and its solution

In the previous video, we found the correct answer for our task and it is 18.75, or is it?

The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect. 

One of the very common tasks on different FIRST Technical Challenge competitions is to collect objects. In this case, these are colourful specifically shaped plastic object or in simple terms - balls.

In this 10 out of 10 tutorial we demonstrate the accuracy of the robot when we use acceleration in its movements. The robot has not sensors attached to it and it is not making use of it's internal sensors. The goal of the tutorial is to give you the understanding and to make a demonstration of how difficult it is to consistently reach a mission model without the use of sensor even when we use acceleration.

With this 10 runs we demonstrate the consistency and reliability that could be achieved with a LEGO Education SPIKE Prime robot and a 2-states simple line following algorithm. It is not bad. Still there are some things you should consider when using this program and one of the things is the use of the timers

On the topic of following lines with a robot there is a way to make the robot follow the line a little more precisely. This method is called "Multi-states" program. Or at least we call it like this. In this tutorial you will see how we program 5 state for the robot line following program. This could be particularly important with FIRST LEGO League competitions where we must build consistent and reliable robots.
