LEGO MINDSTORMS EV3
EV3 basics course. Gyro Sensor. Why is the robot turning to a different angle (part 2)
Turning with the Gyro Sensor on a specified angle and stopping there have never been easy. It is not going to get any better. However, this is not a problem of the Gyro sensor. The problem is in the way we develop our programs.

Strange Bot - LEGO Robot with two motors in reverse direction
This LEGO Mindstorms robot is strange. Can you guess what is strange about it?... The motors are placed in a reverse direction. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you make the robot move forward with a Tank Block in the EV3-G software it will just rotate. To make the robot move forward, you will have to make one of the motors rotate forward and the other one - rotate backwards.
The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction. Also, it is quite fun.

Balancing the Jib of the Crane
Balance is of utmost importance when we talk about constructions. In the case of cranes, balance is even more important. If a crane is not well-balanced, it may easily fall due to its weight and cause a lot of damage. Now, we will see how we can balance our crane.

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.
