FIRST LEGO League Challenge Programming

There are several ways of programming FIRST LEGO League Challenge Robots. The two most popular are EV3-G, which is also referred to as EV3 Lab, and a new language created by LEGO Education based on Scratch. The latter language was originally introduced with the SPIKE Prime set when it debuted in 2019. A version of this Scratch-based language called EV3 Classroom is now also available for programming EV3 robots on Apple Mac computers.

Mindstorms EV3 Lab Software

Mindstorms EV3 Lab also known as EV3-G was the main programming language provided by LEGO Education for the MINDSTORMS EV3 sets until fall 2020. EV3 Lab is graphical programming language where programming blocks are arranged horizontally. It is quite different from traditional programming languages.

Mindstorms EV3 Classroom

Mindstorms EV3 Classroom is a graphical programming language for the Mindstorms EV3 sets. It became the standard software for the EV3 Set for those running Windows 10 and macOS Catalina 10.15 in the fall of 2020. The Mac version also works with macOS Mojave 10.14. Those with earlier operating systems should continue to use EV3 Lab.

EV3 Classroom is based on an educational language called Scratch and is quite similar to Word Blocks, the graphical language provided by LEGO Education for its SPIKE Prime set. LEGO Education has also announced that EV3 Classroom will become available for and Chromebooks.
