Frequently Asked Questions

What is FIRST®?

FIRST® (For Inspiration and Recognition of Science and Technology) is an international not-for-profit organisation founded by inventor Dean Kamen in 1989. FIRST prepares young people for the future through a suite of inclusive, team-based robotics programs for ages 4-18 that can be facilitated in school or in structured afterschool programs. Boosted by a global support system of volunteers, educators, and sponsors, teams operate under a signature set of FIRST Core Values to conduct research, design, build, and showcase their achievements during annual challenges.

What is FIRST® LEGO® League?

FIRST® LEGO® League is an international program created in a partnership between FIRST and the LEGO® Group in 1998. Each year, the program announces an annual theme, which engages teams of young people in authentic scientific research and hands-on robotics design using LEGO products.


FIRST LEGO League introduces science, technology, engineering, and mathematics (STEM) to children aged 4 to 16 years. Three divisions inspire young people to experiment and grow their critical thinking, coding, and design skills through hands-on STEM learning and robotics. From Discover (Junior and Senior Infants), to Explore (First to Fifth Class), and then to Challenge (Sixth Class to Transition Year), students will understand the basics of STEM and apply their skills in an exciting competition while building habits of learning, confidence, and teamwork skills along the way. 


Learn more here: https://www.firstlegoleague.org/about

What is FIRST® LEGO® League Challenge?

FIRST® LEGO® League Challenge is a global STEM (science, technology, engineering and maths) programme for teams of young people aged 9 to 16 years, to encourage an interest in real world themes and develop key skills that are crucial for their future careers. Young people work together to explore a given topic and to design, build and program an autonomous LEGO® robot to solve a series of missions.


In Ireland, Challenge is open to students in Sixth Class to Transition Year, and is delivered in one of two ways:

Tournament - teams of up to 10 participate in regional tournaments leading to national and international events

Class Pack - for delivery to a larger group, leading to an in-house event

What is UNEARTHEDSM?

UNEARTHEDSM is the theme for FIRST® LEGO® League in 2025-26. In the UNEARTHED season, FIRST LEGO League teams will use creative thinking and LEGO technology to unearth new findings about ourselves and our collective communities to help build a better world.

What is the Challenge Class Pack?

FIRST® LEGO® League Challenge Class Pack is an ‘in house’ version of the Challenge programme. It gives teachers and community leaders the opportunity, resources and guidance to run and deliver the programme within curriculum time or with a larger group of children.

Who are Creative Hut?

Since 2010 Creative Hut, formerly Learnit, has been on a mission to 'inspire the creators of tomorrow by making learning fun for the children of today'. We are the delivery partners for FIRST® LEGO® League in Ireland and are proud to partner with FIRST on this exciting programme.

Who is Dean Kamen?

Dean Kamen is a prolific inventor (AutoSyringe, Segway, iBOT), entrepreneur, and tireless advocate for science and technology. His passion and determination to help young people discover the excitement and rewards of science and technology are the cornerstones of FIRST, which he founded in 1989. Kamen holds over 1000 patents, but says that FIRST is the invention he is most proud of, and predicts that the 1 million students who have taken part in the contests so far will be responsible for some significant technological advances in years to come.

What is the role of the teacher or coach?

The role of the teacher or team coach in FIRST LEGO League Challenge is to organise, encourage, motivate, support and guide the team. The coach doesn't need to be an expert LEGO builder or coder, in fact it's probably better if they're not: the team will learn far more by solving problems themselves.


The IET has an explanation of the role of the coach, including some useful do's and don'ts, on their Teachers and team coaches page.

I'm a teacher or coach: how do I get started?

As a first-time coach, there's a lot to take in! We've put together this guide that will help you get up and running:

Getting Started Guide for Teachers and Coaches (pdf) - actions to take before and during your first team session using SPIKE Prime


From there, the documents and links on the various tabs of this Resources page should cover most of what you need to know.

When will the Tournaments take place?

We plan to hold most Regional Tournaments in January and February 2026, with the All Ireland taking place in March 2026.

The centre button on my SPIKE™ Prime Hub is flashing, what does it mean?

Orange

Your Hub's battery is running low (under 20% charge). Connect the Hub via the USB cable to begin charging the battery.


Red

There’s an extended load on the Hub. Turn off the Hub and let it cool down for 15 minutes.


Purple

A Hub firmware update is in progress.


The colour of the centre button can be controlled by a program running on the Hub, so check that your code isn't making it flash!

The Bluetooth button on my SPIKE™ Prime Hub is flashing, what does it mean?

Blue

The ring around the Bluetooth button flashes blue when you press the button to initiate pairing, and is solid blue when a connection is established. It remains off if a USB connection is established.

How do I replace broken or missing LEGO® pieces?

Contact LEGO Service through one of the links below, depending on your needs:


Bricks & Pieces (link) - online service to replace small numbers of missing or broken parts in new sets, or buy additional parts

LEGO Service (link) - contact form to report missing bags in LEGO Education sets; be sure to mention FIRST LEGO League Challenge

What does this Word Block do and how should I use it?

In the SPIKE App, click on Help and then Word Blocks to get a complete description of all of the Word Blocks that are available.

How do I use Python to program my SPIKE™ Prime Hub?

In the SPIKE App, start a new project and select Python in the pop-up where you name the project. When the programming canvas is open, an on-screen Knowledge Base describes the Python functions that are specific to SPIKE Prime, and includes a Getting Started section. Note that SPIKE Prime uses MicroPython, so not all features and functions of the Python language are available.


The Python chapter from the Computer Science for Leaving Certificate book is available from the Golden Key website.


Sources of more general information are the official MicroPython and Python websites, and tutorial sites like W3Schools. 

What software should we use for our presentations?

You can use any package you like to prepare your presentation: PowerPoint, Google Slides, Canva, or anything you're comfortable with. It doesn't have to be a slide-based presentation: you could make a video, or present everything live with props or other visual aids - whatever gets your message across!


Internet connectivity and an overhead projector are usually available at Tournaments; however, we strongly recommend that you don't rely on an internet connection for your presentation (download it to your device), and we also suggest that you have printed copies to give the judges (in case of compatibility problems with the projector).

Should I upgrade to SPIKE App 3 or not?

Yes! There are a number of much-needed improvements in SPIKE App 3, particularly in the area of Bluetooth connectivity. Some points to note:


1. Upgrading to SPIKE App 3 triggers a firmware update in your SPIKE Prime Hub, after which it will no longer work with SPIKE Legacy App (SPIKE App 2). The Hub can be downgraded again if required, but you may need administrator rights on a Windows PC to install the required drivers. In case of an unintended Hub update, contact us for more information. See also the Hub Downgrade page.


2. SPIKE App 3 has fewer movement and motor blocks available, and some of the blocks have fewer options than in SPIKE Legacy App (SPIKE App 2). While this is intended to reduce confusion by simplifying the palette of blocks, it means that some familiar blocks that students have been using up to now will no longer be available. LEGO Education lesson plans have been updated to reflect this change. See also the Word Block Updates from LEGO Support.


3. SPIKE App 3 can open programs written in SPIKE Legacy App (SPIKE App 2) and will attempt to convert unsupported blocks. However, this is not 100% reliable and we recommend that programs be completely rewritten. It may be helpful to take screenshots of legacy code blocks to make this easier.


4. SPIKE App 3 has a new Python API, and existing Python programs will need to be rewritten. A comprehensive API reference is built into the App.
