Scratch (Word Blocks) program for a multiple states

Scratch (Word Blocks) program for a multiple states algorith for line follow with Color Sensor from LEGO Education SPIKE Prime

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.

This program was intended for and tested on the Gazon robot

How to open?

Programs with extension *.llsp could be opened with version 2 of the LEGO Scratch Word Blocks software. It is also known as 'SPIKE Legacy'. You can download it from LEGO website. You can also visit spikelegacy.legoeducation.com to use it online Note that this programs are incompatible with version 3 of the software.

Courses and lessons with this Program

This Program is used in the following courses and lessons

LEGO Education SPIKE Prime Programming for competition with Word Blocks

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.

Color Sensor - Follow a line with a multiple 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.
