Improving FLL Robot Game. Task. 9 out of 10 repeatable operations
The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works.

Improving FLL Robot Game. Losses in mechanical systems and especially in gears
Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot.

FLL 2018: How to accomplish M05 (extract and collect) from FIRST LEGO League 2018 Into Orbit. Review
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION. On every robotics competition we have the challenge to collect, carry and return to base a number of objects. It is just in different way every time.

FLL 2018: How to accomplish M14 (throw precisely) from FIRST LEGO League 2018 Into Orbit. Review
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M14. METEOROID DEFLECTION. The mission is a simple throw of a ball. But of course the ball should reach a specific mission model and arrive at a specific place. And that's always challenging.

Improving FLL Robot Game. The planetary mechanism for Lifting the robot
If you've done the calculation following the previous tutorials you would arrive at a result of 18.75 rotations. But this is not the correct answer. The calculation is wrong, because the math model that we've built, although kind of obvious, is not correct. When experimenting the correct number of rotations would be 37.5. This is a large difference. Two times larger. Exactly two times large. Something should be happening here - and this thing is "planetary mechanism"

Extracting the logic for finding minimum an maximum into a new block
One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.

How to display on the screen the calibrated minimum and maximum values from the Array
A common question is how to display arrays on the LEGO Mindstorms EV3 brick screen. Displaying values from an array is not different from any other display operation. In this tutorial, we would look at displaying two specific values. The minimum and the maximum for a specific sensor from the Advance Calibration Course Section

Calculated read of calibrated value for Light/Color LEGO Mindstorms sensors
Following the Advanced Sensor Calibration course section, it is time to extract the logic for getting a calibrated value into a new block. This block will have an input and on this input, we give the port number. The block will return the calibrated value for this port number. We've built all the other blocks only because of this almost final video here.

How to display on the screen all the values from an array, using an "Iteration"
In this tutorial, we show you how to display all the values from an EV3-G array on the EV3 brick display. We are using an array Read Operation along with a loop. We are also detecting the loop counter and using it as an index to an array. It's basically the only viable way to do it. The process is commonly referred to as - "Iteration over an array" (although we still do not have an iterator in the programming language, we promise that one day we would do the super advance videos on "iteration" using the LEGO MINDSTORMS robots")

FLL 2018: How to accomplish M05 (collect) in Into Orbit. Review with Box Robot 1
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION, but compared to one of the other tutorials about this mission, in this specific tutorial we are using Box Robot 1 and a multi-purpose attachment. The attachment is designed for two missions and one of the missions is the Extraction

FLL 2018: How to accomplish M06 (precisely push) from FIRST LEGO League 2018 Into Orbit. Review
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.

Hardcode read of calibrated value for Light/Color LEGO Mindstorms sensors
Following the Advance Sensor Calibration course section, we found the min and max values detected by each sensor. Now it is time for the real deal of the calibration. Detect the current value from the sensor and find what is the percentage of this value for the range between min and max.
