Video tutorials

In this video tutorial we would look at the mission run for M09. STRENGTH EXERCISE. The mission is to lift a heavy object in the air. And that could a complex mission. It requires to use gear wheel and the attachment should be quite strong. The tutorial contains only the mission run on the field. We accomplish a single mission. 

The M08. AEROBIC EXERCISE is one of the very common types of mission in FIRST LEGO League robotics competitions. I think this pattern of missions was first introduced with the growing abilities of the participating students that were constantly reaching the maximum number of points. So the competition introduced mission that require a lot of time - 20-30 seconds, are time consuming and are complex. They requires a lot of moves. This here is a video tutorial on how it could be accomplished

In this video tutorial we would look at the mission run for M06. SPACE STATION MODULES. The missions is to precisely push a mission model into an opening. In almost any FIRST LEGO League competition there are such missions. The tutorial contains only the mission run on the field. We accomplish a single mission. 

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M08. AEROBIC EXERCISE. This again is a very interesting mission from the competition. We could learn a lot of basic principles in the field of robotics. This mission requires the robot do to something very fast and many times. 

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished. 

This video tutorial contains a details explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M06. SPACE STATION MODULES. This again is a very interesting mission from the competition from which we could learn a lot of basic principles in the field of robotics.

Here is Lintu. It is a marvelous LEGO Mindstorms EV3 Animal robot that looks like Kiwi, the famous New Zealand bird. It is quite rare to see a Kiwi bird in person. But fear not, we've prepare a robot that looks almost exactly like the original.

In this video tutorial we would discuss the M13. OBSERVATORY mission from the FIRST LEGO League robotics competition 2018-2019 Into Orbit. This is an easy mission. You can accomplish it by pushing the level with the robot. The challenge is that there is not enough space to move with the robot around the attachment. Let's discuss how we could achieve it. 

This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the M06. SPACE STATION MODULES mission 9 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission. It moves forward and attaches the space station module with the space station. 

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M04. CRATER CROSSING. These are some of the funniest missions at this robotics competition. Try to move over an obstacle with a robot and if you manage to return back to base without bumping into other mission models that would be great. 

This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever. 

The M07. SPACE WALK EMERGENCY is one of the most interesting missions in FLL the we've even seen. This video tutorial demonstrates a mission run for Mission 07 Emergency Walk in FIRST LEGO League 2018-2019 Into Orbit robotics competition. The tutorial contains only the mission run on the field. We accomplish a single mission. 

This video tutorial contains a detailed description on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called Emergency Walk, which I think is one of the most interesting missions ever in FIRST LEGO League competitions. Join me in for a short explanation. 

This is the fifth and the last run of the Nightbeast team. Robot goes out of the base, do missions:

1. M11 - Escape Velocity
2. M13 - Observatory 

and stays on the field. It's a common practice for the competitors to left the robot on the field after the last run. This allows them to do some important points at the end of the match. 

In the third run Nightbeast team solves Mission 04 - Crater Crossing and partly Mission 03 -  3D printing and Mission 014 Meteoroid Deflection:

1. Eject the 2x4 Brick by placing a Regolith Core Sample into the 3D Printer.
2. Crater Crossing
3. Tries to score a meteoroid( tries to shoot a ball)

In the second run Nightbeast team solves different tasks from two missions - M05 Extraction and M06 Space Station Modules:

1. Insert the Tube Module into the Habitation Hub port, west side 
2. Move all four Core Samples so they are no longer touching the axle that held them in the Core Site Model
3. Place the Gas Core Sample completely in Base

Mantissa, a LEGO Mindstorms Robot, moves and attacks. It uses the ultrasonic sensor and it's two special hands. Follow the building instructions and download the prepared program to directly use the robot.  

We've recently received a number of question on how could the SUV box robot be charged. The answer is simple - you detach the back pane. The question and topic of detaching modules from a robot and attaching them again is really interesting and powerfull and yet not very often implemented in many robots. 

Football with robots could be quite fun. Football with LEGO Mindstorms robots is one of the popular categories for competitions with LEGO Mindstorms Robots. 

There are a few main challenges with box robots and in the following tutorial we would like to resolve them. Read on and let's see how we could do this. 

As we are already off the season we decided to look back at the competition. First, we will take a look at the working solution for FIRST LEGO League 2017 Manhole Cover. This was generally accepted as one of the most difficult missions during the competition. We've built a single attachment to accomplish it. 

(we are releasing the video without explanations and will add the explanations later)

We should multiply the error by a certain number and then add it to the steering of the LEGO Mindstorms Steering block. In this way, by changing the coefficient we change how much/fast should the proportional part influence the steering of the robot. 

After we take each sample, we perform calculations and these calculations could take different time. It is important to know how much time does it take to perform the calculations. In this video tutorial, we would data log the time and plot the data.

Let's record the values of the Gyro Sensor while the robot is moving and is trying to keep its orientation straight. This is an interesting experiment and we will have to use file access to write the values to a file. 

This video tutorial contains the final 2 programs for moving straight with a LEGO Mindstorms EV3 robot. The first program is for proportional compensation that just keeps the robot orientation straight, while the second program is for Integral compensation that returns the robot to the straight line when the robot makes a mistake. 

In this video tutorial, we would do a few experiments with the coefficients for the Integral compensation. There are actually two coefficients - "c" and "b"
