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.
This second part continues with importing two previously developed in Episode 53 blocks into our program. With them we can for align to lines. We program the robot to align to the cross line and start following it.
In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.
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.
The LEGO Mindstorms EV3 set comes with two LARGE motors. But even though these motors look almost the same they are not quite the same. There are always some differences in their behaviour. If you have more than two motors, because you bought them or you won them somewhere at a competition, it is worth doing an experiment to find which pair of motors works best.

Laboratory 2.0 is a second and lighter version of the Laboratory. The new version of the robot replaces its motor with a gyroscope and uses a lightweight flip. Programming this robot requires a well-developed abstract thinking. The main purpose of the robot is to measure the volume of the bubble placed in it only by the values measured by the sensors.
The construction has a valve with which you can let the air out of the balloon at different speeds.
How exactly the balloon is placed in the robot is explained in this lesson.
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This is the simplest module for constructing and programming. At the bottom, a channel is left for the cable to pass through.
The Laboratory is a robot that tests your programming skills. You will have to measure the volume of a balloon, only by the values you receive from the sensors.
It has a valve, that allows you to deflate your balloon at different rates.
How to place the balloon in the robot is explained in this tutorial.
This is a vehicle that is used to help you to learn programming, to experiment with addons, attachments and constructions. It has a frame. Which is nice. A frame is always nice.
It has two wheels at the back, but this is needed only if you have them.
This project contains two programs. Both programs are made for Omusbot - LEGO Mindstorms EV3 sumo robot. The first one is a simple program that makes the robot spin, until it detects something with its ultrasonic sensor and then it attacks forward until it detects the black border of the sumo field, at which point it goes back two rotations. The other program is does the same thing, but it can detect also if the robot is being pushed from the back. This is achieved using behaviour programming which is explained here: How to make a behaviour program?
The way you move the robot is always imprecise. Don't TRY to fight with this. Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind.
This project works with the Chronos - LEGO Mindstorms EV3 clock robot. It makes the hands of the clock start moving like they would on a real clock. There are two programs in the project, one that controls hours and minutes hands, and second that controls seconds and minutes hands of the clock.
This project works with the Chronos - LEGO Mindstorms EV3 clock robot. It aims to teach you to read the clock by showing a randomly selected time and giving you 5 seconds to guess what it is. It then shows you the correct answer and returns to its starting position.
