This robot could quite possibly be build from a single EV3 core and EV3 resource sets. It uses fewer parts and only three motors. There are additional parts that could be skipped when building the robot and we have added these parts only as to make the construction more complete.
Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.
In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
In this video tutorial we will reach a specific location on the field 10 times. This programs demonstrates the accuracy and consistency of a program that used the Motion Sensor to detect the angle at which the robot rotates. At the end of the tutorial you will have a visual and clear picture of what you could expect from this basic usage in terms of consistency and accuracy. This might be enough for some cases and it might not be enough for others.
Very simple and basic introduction to the color sensor in the LEGO Mindstorms EV3 set. The first program is to stop at a line. Then we can move from stoping at line to counting lines and even more complex tasks.
This is the first, but not the last video tutorial of the course where we reach a specific mission model in a consistent way. We use the Motion sensor and only some basic principles like turning to an angle. If we use the principles in this tutorial and then build an attachment for the mission model we will have a pretty consistent way of accomplishing the FIRST LEGO League mission
In this video tutorial we demonstrate how the robot could accomplish the Power Switch mission. Power Switch consists of a cube with a lever and the lever should be rotate to 180 degrees. This mission model was very close to a FIRST LEGO League 2012 competition mission which was called - Oven. The robot, the attachment adn the mission model are built form a single LEGO Mindstorms Robot Inventor 51515 set and with the tutorial you will learn how to use an active attachment with 2 gear wheels to complete such missions.
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.
We extract the Proportional Line Following algorithm into a new block with parameters. This allows us to experiment with the Threshold, Constant Speed and Relaxation Coefficient. You can now easily use the block in you other programs without having to implement it.
This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.
In this lesson I would like to show you how to build a LEGO Mindstorms competition robot and tell you how we have designed the construction used in the videos so far. Surely it isn’t perfect, but it is a good start.
This animated video tutorial demonstrate the use of a lift attachment to accomplish loops mission. It is a lift attachment with a circular motion
In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.
This animation demonstrate the use of an LEGO MINDSTORMS Robot Inventor attachment to lift a lever of a mission model. The mission model is the Power Switch mission model where you have to move the lever from one side of the mission model to another. The principle of the attachment is powerful and easy to implement for all kinds of missions.
The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
In this video tutorial we look at Acceleration and Deceleration with a LEGO Education SPIKE Prime robot. The goal of the tutorial is to demonstrate the accuracy of the robot when we us default acceleration and slow acceleration.
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 video tutorial we demonstrate the use of the motion sensor and how it could be use to turn precisely to 90 degrees. We demonstrate some of the caveats of the sensor and how sometimes it does not work as expected. Like you set the robot to turn until the sensors detects 90 degrees and at the end the robot is not at exactly 90 degrees.
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
This videos tutorials demonstrated the robot accuracy in 10 runs one after the other. 5 of them are with the robot moving slow and 5 are with the robot moving fast. See for your self what is the accuracy achieved only with the move blocks of the robot.
Use the color sensor to count the lines and stop on the third line. We do not use the wait block for this.
In this tutorial we demonstrate how accurate the robot is when we are moving it slow vs when moving it fast. The point of the tutorial is to show that moving slowly is generally much more accurate. It is not accurate enough for a FIRST LEGO League competition, but if you have to move without the use of the sensors you can at least move slow.
Based on your feedback we've build a course for introducing new students to the LEGO Mindstorms EV3 programming and construction. It is designed for school groups, competition teams and students alone in home that can get our feedback on their progress
This video tutorial demonstrates the accuracy and consistency of the robot behavior when we use only the blocks for moving the robot without any sensor. Spoiler alert - the robot is not consistent and it is not accurate.
This tutorial in an animated demonstration of how a LEGO Education SPIKE Prime robot could turn precisely at 90 degrees using the Motion Sensor. The goal of the task is to download the program and rotate at exactly 90 degrees. Because of this precise rotation it is easy to know where your robot is on the field and to program the robot to perform in a reproducible way. To download the program check out the courses in which the tutorial is used.
In this video tutorial we start with the basic of the basic, eg. how to move. We use the block from LEGO Education SPIKE Prime Word Blocks software. It is based on Scratch. The goal of the tutorial is to demonstrate how we can move and to teach something very important - the robot moves inaccurately
In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.
