Scratch (Word Blocks) program for follow and align with Color Sensors from LEGO Education SPIKE Prime

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.

This program was intended for and tested on the Gazon robot

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.

Follow and align

In this video tutorial we show how you can build robots that position on the field consistently and reliably by following and line and then aligning to a line. We also demonstrate the concept of "double align" which is quite powerful and even if there were some mistakes they will be handled.
