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 [[Wikipedia:Scratch (programming language)|Scratch]] called Word Blocks. A version of this Scratch-based language called EV3 Classroom is also available. LEGO also provides a special version of a line-by-line language called Python for programming robots.
There are several ways of programming ''FIRST'' LEGO League Challenge Robots.  The most popular new language created by LEGO Education is based on [[Wikipedia:Scratch (programming language)|Scratch]] called Word Blocks. A version of this Scratch-based language called EV3 Classroom is also available for those using EV3 sets rather than SPIKE Prime. LEGO also provides a special version of a line-by-line language called Python for programming robots.

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 PCs with the 64-bit version of Windows 10, Chromebooks and Macs using 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.

There are several ways of programming FIRST LEGO League Challenge Robots. The most popular new language created by LEGO Education is based on Scratch called Word Blocks. A version of this Scratch-based language called EV3 Classroom is also available for those using EV3 sets rather than SPIKE Prime. LEGO also provides a special version of a line-by-line language called Python for programming robots.

General

SPIKE Prime Software

SPIKE Prime Word Blocks (Scratch)

SPIKE Prime Icon
Sample Word Blocks program

The main programming language for SPIKE Prime is called Word Blocks, which is based on Scratch. LEGO Education provides an online introduction to the set and its software. The software app can be downloaded and installed before or after receiving the SPIKE Prime set.

  • SPIKE Prime App Version 2 (2022 version)
  • SPIKE Prime App Version 3 (latest version)
    • This new version of the app includes a variety of improvements but also reduces the number of choices for Movement blocks.
    • LEGO Education description of SPIKE Prime App Version 3
    • Youtube video about the changes in App Version 3
    • The current version of SPIKE App Version 3 will allow you to open projects saved using Spike App version 2 also known as Legacy.
      • When you open Word Block projects created using Version 2 they are automatically translated so that the program will work in Spike App 3.
      • To open a project created with Version 2
        • Click on File then Open.
        • In the File Name field type *.* to get it to display your Version 2 projects by showing each name followed by ".llsp".
        • You can then select and open one of your Version 2 projects.
      • Even though it will be translated to App 3 you may need to make some adjustments.
    • Slides showing how to convert Movement Blocks from App Version 2 to Version 3
    • If you upgrade to version 3 of the SPIKE Prime App, it will update your hub to new firmware that works with the new app.
    • If you decide to go back to version 2, you will need to change the firmware back to a version that works with App Version 2 of the App. See this link to downgrade your Hub firmware to the compatible version.

Slide Set for Coaches

Each year ORTOP holds workshops in the summer and early fall.

Introductory Exercises for Coaches

Season-Independent Lessons Using Small Printable Mat

One of the best ways for team members to learn how to program a LEGO robot is to have simple challenges with guidance on how they might solve those challenges. And, these challenges can performed on a 2x3 foot mat, allowing small groups or individuals to learn the skills they'll need for the annual challenge on the full-size mat. With this in mind, ORTOP has developed a set of simple lessons that feature such challenges that are backed up by short videos that give hints on how to solve the challenges. Follow this link to find out more.
