Straight at the end of the program - EV3-G program for returning to straight orientation

In this program, we return the robot to a straight orientation at the end of the program. If there is not enough time for the Mindstorms Gyro sensor the correct the orientation of the robot before the end of the program, then we should do it at the end.

The robot is not straight at the end of the movement?

We keep the robot orientation straight while moving, but when we stop the robot could be in a different orientation. This applies for both using the Mindstorms Gyro Sensor when moving straight or the Mindstorms Color sensor when following a line. In this video tutorial, we will do a few examples of when an how this could happen.

Moving Straight with LEGO Mindstorms EV3 robots

One of the most controversial topics when it comes to LEGO Mindstorms robots is how to make them move in a straight line. This is a problem that has caused a lot of confusion among teachers, parents, rookie teams and students. The robot makes about 2-3 centimetres error for every meter, which is about an inch for every 3-4 feets. In this course, I would like to discuss the different ways in which you can improve the behaviour of the robot and how you could make it move in a straight line with the help of the LEGO Mindstorms EV3 Gyro Sensor.

Moving in straight line with LEGO Mindstorms EV3 robots

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.

PID Algorithm for Moving Straight with Gyro Sensor. Proportional Part

The first part of making the robot move straight is to keep it oriented straight. While it moves it could make an error and turn slightly to the right and then the program should turn in back to the left to make its orientation straight. In this video tutorial, we would discuss how to implement a program to keep the robot orientation straight even when we are pushing or pulling it to either side and in the same time it has different wheels.
