In this video tutorial we follow a line 10 consecutive times. In this way we demonstrate whats the consistency that you could expect from the robot when following a line with a multi-states algorithm.
On the topic of following lines with a robot there is a way to make the robot follow the line a little more precisely. This method is called "Multi-states" program. Or at least we call it like this. In this tutorial you will see how we program 5 state for the robot line following program. This could be particularly important with FIRST LEGO League competitions where we must build consistent and reliable robots.
With this 10 runs we demonstrate the consistency and reliability that could be achieved with a LEGO Education SPIKE Prime robot and a 2-states simple line following algorithm. It is not bad. Still there are some things you should consider when using this program and one of the things is the use of the timers
In this video tutorial we demonstrate the classic algorithm for following a line with robots. It is widely used in FIRST LEGO League competition and could be applied to LEGO Education SPIKE Prime and to other robots also. The algorithm follows a line by moving to the left and to the right and trying to stay at the edge of a black line.
We use a sensor so the robot must be reliable and accurate right? Wrong. The robot is not reliable and accurate only because we use sensors and that's really important during FIRST LEGO League competition. There is a reason for this and in this tutorial we demonstrate and explain how the robot behaves with a basic use of the Motion Sensor to move straight. As a result you will learn why is it important not to stop at this stage and to go to the next level with more advance use of sensors.
In this video tutorial we use the LEGO Education SPIKE Prime Motion Sensor to reach a mission model on the field. It's a basic use of the motion sensor that we will extend in the next few tutorials and in the same time we take the opportunity to demonstrate what a MyBlock is and how to develop one. As a result of this video you will learn how to make the program easier to read and maintain by organizing the blocks in the program in special MyBlocks that couple them all together.
We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.
One of the easiest ways to improve the accuracy of LEGO Education SPIKE Prime robots is to use acceleration and deceleration when moving. This also applies to LEGO Mindstorms EV3 and LEGO Mindstorms Robot Inventor and generally to most robots that we know of. This tutorial demonstrates how acceleration and deceleration could be used and what improvement in accuracy and consistency you could expect. This is quite useful for FIRST LEGO League and other robotics competitions.
In this video tutorial we take a look at the consistency of a robot that uses acceleration and deceleration to turn precisely. We use the motion sensor. In 10 consecutive runs we demonstrate what could you expect from the robot when it comes to consistency.
In this video tutorial we explore acceleration and deceleration and how to make the robot turn precisely by using acceleration and deceleration. The goal is for us to demonstrate a program that turns the robot to 90 degree. In the first 45 the robot is accelerating and in the second 45 it is decelerating.
This LEGO Education SPIKE Prime video tutorial demonstrates the difference in turning slow and turning fast and using the Motion sensor to understand the orientation of the robot. We do 10 consecutive runs. The goal is to understand what can you expect from the robot behavior in terms of consistency.
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 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
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.
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.
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.
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.
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.
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
Counting lines and stopping on the third is the subject of this video. It is important to know how to do this in order to conduct more than one experiment in STEM classes (if we consider that each line is an experiment)
