What is an LMSP file?

An LMSP file is a program created using LEGO Education EV3 Classroom, a block-based code editor that students use to learn to code. It contains source code written in the Scratch programming language, which is displayed as block-based code in EV3 Classroom. LMSP files are used to program LEGO robots constructed using the LEGO MINDSTORMS Education EV3 Core Set.

LEGO Education EV3 Classroom is a cross-platform application that allows students to create programs for use with the EV3 Intelligent Brick. The EV3 Intelligent Brick is a miniature, programmable computer that students use to control LEGO robots, which are built from the LEGO MINDSTORMS Education EV3 Core Set.

Programs that students create using EV3 Classroom are saved as LMSP files. In EV3 Classroom, the code that LMSP files contain appears as blocks, which students can drag and drop to change the functions their program includes. After a student has finished editing the program their LMSP file contains, they can install the file on their EV3 Intelligent Brick. They can then attach the Brick to a LEGO robot designed to execute their program and watch as the robot performs the functions their program contains.

NOTE: LMSP files are Zip-compressed files that contain an .SB3, .SVG, and .jsn file. Students will likely never have to decompress an LMSP file, but doing so and examining the file's decompressed contents could be a valuable educational exercise.

How to open an LMSP file

You can open LMSP files in LEGO Education EV3 Classroom (cross-platform). To do so, select File → Open File from the program's menu bar. Then, navigate to and open your LMSP file.

To install an LMSP file on your EV3 Intelligent Brick, you must pair the Brick with your computer. You can do this by turning on the Brick's Bluetooth or connecting it to your computer using a USB cable and then pressing the connect button found in LEGO Education EV3 Classroom. Then, follow the instructions included with EV3 Classroom to install your LMSP file on your EV3 Intelligent Brick.
