In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors while moving backward. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.
This program was intended for and tested on the Gazon robot
In this program, we demonstrate how to follow a line with a SPIKE robot and then align to that line. That way the robot can position itself at specific distances on a predetermined path.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect an intersection with another color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

In this program, we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect and stop at the second intersection with the aid of another color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

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.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. since we are measuring reflected light rather than the color of the line, we can and have implemented multiple states line following.

In this program, we present an "MY BLOCK" that follows a line presented as a yaw angle from the robot's starting position. If the program acts differently when tested again, then the most likely problem is the direction the robot is facing, when starting the program. Make sure to place the robot at the correct starting position with the correct facing direction, before every test.

Two concepts are important for robotics competitions - consistently navigate and position the robot exactly where we need it to be on the field, and builing attachments that would accomplish a mission once we have reached it. This course is focused on the first part. The second part is the whole FLLCasts platform, but start at FIRST LEGO League with LEGO Education SPIKE Prime. "Challenge" competition for 9-16 years old
The goal of this course is the help you learn to program LEGO Education SPIKE Prime robots to behave consistently and reliably during competitions. As a language we use LEGO Education SPIKE App Word Blocks which is based on Scratch. We look at a lot of concepts that could be used for FIRST LEGO League and World Robot Olympiad competitions - eg how to follow a line fast, slow, in a smooth way, with 5 states. Also how to align to lines, how to do double alignment, how to keep a straight line with motion sensor.
To successfully advance at competitions we need to understand two concepts - how to reliably and consistently navigate the field and position the robot exactly where we need it to be on every run, and how to build attachments that would accomplish a mission model once we have reached it. This course is focused on the first part. The second part is the whole FLLCasts platform, but start at FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old.
The goal of this course is to help you learn to program LEGO Robots using Scratch and make them behave consistently and reliably during competitions. As a language we use LEGO MINDSTORMS App Word Blocks which is based on Scratch. We look at a lot of concepts that could be used for FIRST LEGO League and World Robot Olympiad competitions - for example, how to follow a line fast, slow, in a smooth way, with 5 states. Also, how to align to lines, how to do double align, how to keep a straight line with a motion sensor.
Unfortunately, LEGO discontinued the robot series during the making of this course which is why it's kind of shortish. You could use the SPIKE Prime course for a more in-depth analysis.
In this course, we demonstrate and explain example solutions for the FIRST LEGO League 2021-2022 Cargo Connect competition. Just like every year, we share solutions only after the season is over. In this course, you will find examples and principles of building attachments and will learn how to program consistent and reliable robots for each mission. You can follow the course, and as you go through each mission, try to replicate the solutions to understand the programs and explanations. Upon completion of the course, you will have many new ideas about how to approach the missions in every FLL robotics competition and how to help your team score more points.
