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.
The Gyro sensor can be positioned horizontally, vertically or at a random angle. Have you ever wonder what does the gyro detect when it is positioned vertically. This is the subject of this video tutorial for the LEGO Mindstorms EV3 Gyro Sensor.
(LEGO humans of course, not real humans :) ). Working on World Robotics Olympiad 2014 elementary challenge. Collecting modules, bringing them together and lifting them. A very funny and interesting competition that we would explore in this and the next video tutorials from the series
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.
Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot.
In this tutorial, I will cover the adjustments of the display and the color lamp blocks from the LEGO Mindstorms NXT-G. Today I will show you how to use the color lamp in order to make your robot more interesting or how to display sensors values or try to draw something on the screen of the brick.
Tasks for STEM classroom and home exercise to get you used to using the LEGO Mindstorms Touch sensor. Solve them, build a program, record a video and upload your solutions below.
The comunication between the motors and the controller should be configured in the RobotC software. Each motor could be connected on a different port and the goal of the video is to show you how.
This is a disk image containing a Raspbian OS. The image is modified and set up specifically for the Perfect course. It contains all the needed files, libraries and additional tools that we would use in the course. The file is quite large so be prepared to wait some time while downloading.

Introduction to robotics - The first level of the Robotics with LEGO curriculum for students in second, third or fourth grades. A journey in space, with robots. Various constructions with robots are built. Learn how to control the motors so that the robot navigates around the Sun, the Moon and Earth in various ways. Getting to know the first of the sensors. The robot can feel its surroundings with the help of the Touch sensor and avoid obstacles.
EV3-G program for following and object with the LEGO Mindstorms EV3 robots
EV3 PLF-block for LEGO front-wheel steered robots. The block has two relaxation coefficients – one for steering to the left and one for steering to the right. The aim is to make the robot follow a line smoothly when the color sensor is positioned closer to one of the wheels.
The block has the following parameters from left to right:
These are the programs for our boxing robots and their Joysticks. They are made for a game of two fighters with their respective joysticks, fighting until one is knocked out or its "heart" touch sensor is punched by the other robot. The fighters require the two "leg" motors to be connected on ports B and C and the hand medium motors on port D. The touch sensors should be connected on port 1, however keep in mind that the game may be better without them. The distance sensor has no purpose in the program as it is used only for aesthetics. The joysticks require the motor for forward and backward to be connected on port B and the motor for left and right to be connected on port A. The touch sensor operates the hands and must be connected on port 4.
This Python program is for controlling Gazon, LEGO Education SPIKE Prime competition robot to accomplish FIRST LEGO League (FLL) 2020 RePLAY Challenge mission 05 - basketball using Attachment for FLL 2020 RePLAY Basketball mission
In this 10 out of 10 tutorial we demonstrate the accuracy of the robot when we use acceleration in its movements. The robot has not sensors attached to it and it is not making use of it's internal sensors. The goal of the tutorial is to give you the understanding and to make a demonstration of how difficult it is to consistently reach a mission model without the use of sensor even when we use acceleration.
In this 10 out of 10 tutorials we do 10 runs that demonstrated how consistent and reliable it is to stop at the second intersection. This is useful as it is one of the main ways to figure out how to position yourself on the field.
In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. In this program, we use the sensor value to calculate a number to feed in the "start moving" command. The numbers in this program depend highly on the size of the wheels of the robot, the distance between the wheels, the color sensor reflected light range, the wheels friction, and the speed at which the robot moves. The numbers in the program must be adjusted for every case, and are in no meaning optimal to use as is, in other projects.
This program was intended for and tested on the Gazon robot
