Block for accurate turning on 90 degrees with the Gyro Sensor
This block accurately turns the robot to a specific angle. One of the most useful blocks that you could use during competitions. The block makes the robot turn and when the robot makes an error, the block will correct for this error.
Finally, you can be sure that the robot has turned to the specific angle that you want.
You have three inputs
- Turning angle - the angle that you would like the robot to turn.
- Power - the power that you would like the motors to have
- Correction power - the power during the correction phase.
VERY IMPORTANT: This is a block for EV3-G. You download and import this block from Project Settings->Blocks->Import. If you are using Internet Explorer or Microsoft Edge and you click to download the file it will try to save it as "zip". DO NOT SAVE IT AS ZIP. Save it as "ev3s" or just PLEASE, STOP using Internet Explorer or Microsoft Edge. This will dramatically improve your browsing experience.

Program for returning to the Straight line after the Robot makes an error (Integral compensating)
This is an EV3-G project that contains two programs implementing an Integral compensation - integral part of the PID algorithm. The first program is for a Five Minute Bot and the second program is for Box Robot. The things that you should be careful when using the program for your robot are the direction of the motors in the steering block; whether the motors in the steering block are written as "B+C" or "C+B" and the coefficients in the two math blocks. The coefficients that we've chosen should work for most of the robots, but will probably not work for some of them. If they don't work, write to us, comment below in the comment section or drop us an email.

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.

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.

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.

Data logging the behavior of the LEGO Mindstorms Robot and its Gyro Sensor
This video tutorial is about understanding the "magic". In this video tutorial, we would conduct an experiment and will look at how exactly does the integral part of the PID algorithm compensate for the error that the LEGO Mindstorms EV3 robot makes.

FLL 2018: How to accomplish M09 (lift heavy) 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 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.

Crossed lines (T Sections). Positioning. Part 1.
How do you detect a cross-section and move from following the main line to following the crossing line. In this series of video tutorials we are starting with a very simple solution that could work in most of the cases. It is especially useful for the FIRST LEGO League Trash Trek competition where there is such a section.

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
