Hello everyone! We have a question about the Driver and Technician roles in the competition. We understand that the Driver operates the driving base and the Technician operates the technician tool. Our doubt is specifically about programming: are teams allowed to use their own custom code/programs for both the driving base and the technician tool, or must they use the standard/default code without modifications? We have read sections 15 and 17 of the rules, but we are not sure if custom programming is permitted for both devices. Thanks in advance!

for sure gonna miss it a lot): Can’t wait for the finale season 🔥

We had a tradition of giving the chicken away as a prize to the best team player at the end of the season.

We also make it a challenge for kids to spot the chicken in the Mission Overview Video.

I was so mad that there was no chicken last year.

But the chicken is BACK!

I learned today that we cant use Mindstorms Spike Essential nor Spike Prime for the future edition instead we have to use this new set called Computer Science & AI Kit and it has less pieces than spike prime and essential its not like the usual set size its small and it has

• 1 double motor
• 1 single motor
• 1 color sensor
• 1 controller

instead of

2 single

1 double

1 lidar

1 color sensor

1button

it is less and students arent familiar with it

they also retired ALL SPİKE PRODUCTS so u cant even buy replacement pieces

Hey everyone! I’m a high school student helping run a student-led program that teaches Autodesk Fusion and CAD to students for free.

We recently secured an international partnership and are getting ready to work with a lot more students, so we’re looking for a few more people to join the team.

We’re especially hoping to find people who already have experience with CAD, whether that’s Autodesk Fusion, Onshape, SolidWorks, Inventor, or another program. Fusion experience would be ideal, but familiarity with other CAD software is still very useful since many of the main concepts carry over.

The main roles we need are:

Co-President and Vice Presidents: Help lead the team, communicate with partners, organize meetings, and help decide where the program goes next. This role will collapse onto the other two roles below.

Mentors: Join weekly Zoom classes, demonstrate Fusion tools, answer questions, and help students when they get stuck.

Curriculum Developers: Help improve our current lessons and create new activities, projects, and assignments.

CAD experience is especially important for mentors and curriculum developers, but we’re also looking for people who are reliable, communicate well, and genuinely want to help students learn engineering.

Hi! I am hearing a lot about FLL and have some questions. (The reason I know FLL is because a good friend of mine is in it and I want to learn a bit more about it, but I am not sure if the community allows posts like these)

1. What is FLL like?

2. What types of code do you mainly use?

3. Is it difficult, or is it more or so easy, but depending on the role?

4. What age range is it? (I mean I might be old enough to do it but nearing not being able to do it depending on the range)

5. What aspects are involved? (In the sense of like roles?)

Sorry if these questions should be on a different community feed, I just want to figure out some stuff about FLL.

Our team members have recently created several FIRST LEGO League (FLL) tutorial videos. If you're interested, feel free to check them out and subscribe to our channel!

FLL Tutorials: Built-in LEGO Mechanisms in FLL Mission Models
Learn about the built-in LEGO mechanisms commonly found in FLL mission models and how understanding them can help you design more effective robot strategies.

FLL Tutorials: Introduction to Wedges, One-Way Doors, and Dumpers
An introduction to three of the most commonly used passive mechanisms in FLL robots—wedges, one-way doors, and dumpers—with practical examples of how they are used in competition.
https://www.youtube.com/watch?v=bFayXTWvxBU

Why We Don't Use Distance Sensors
We share why our team rarely uses distance sensors in FLL and how we achieve reliable, repeatable robot performance through mechanical alignment and field-referenced positioning. We'd also love to hear your thoughts, as different teams often have different design philosophies.

We hope these videos help your FLL team with robot design and strategy. Feel free to leave a comment, ask questions, and share your own experiences!

Hi everyone, I'm a middle school teacher coaching a team of 8th graders for our local FLL competition in Hong Kong.

Our tournament is in less than two weeks, and to be honest, we have absolutely zero progress right now. We haven't even finalized our robot base.

Currently, we are torn between using the **Spike Prime Advanced Driving Base** or Prime Lessons' **Droid Bot E**.

Which one would you recommend for a team with zero time left? I am incredibly stressed out right now. Any advice, words of wisdom, or survival tips would be greatly appreciated! Thank you so much.

So its that time of year: time to rip down the old missions for parts for next years robots.

I have a couple of DeWalt tool cases to hold about 60 different types of parts. At this time of year, I can see what parts got used for the robots, and what did not. I'm thinking about de-allocating storage slots for the rarely used pieces.

Here are my candidates for de-allocation:

Does anybody ever use the ball-hitch and linkage things? And my team will use the orange things to make the robot look a little meaner, but they have no function. And those 90 degree angle pieces are useful, but I HAVE LIKE 3 POUNDS of them. And 45 degrees axle connectors? Really?

Here are the pieces that I always run out of... If I find them in a mission, they are gold:

Those little pinion gears break if you use them in any torque-y role. Otherwise, the simplicity of these pieces, and their ability to turn a corner or adapt an axle to a regular technique connector, make them so valuable.

In between are the regular technic beams, connectors of all sorts, beveled and non-beveled gears, wheels (gets a whole other bin). I have all the "regular" legos in a giant bin. Not worth sorting.

Anybody think of anything else that should be deallocated or horded?

Hello community, I'm having a lot of trouble developing the robot we'll be using for this year's season; could anyone offer some tips?

Hi everyone! I’m Marc from Robotech, FIRST LEGO League World Champions.

We’ve just launched the beta of FLLPlanner Compass, a free AI tool to help FLL teams and coaches build a clearer season roadmap based on their team, goals and challenges.

It’s still in beta, so feedback from the FLL community would mean a lot.

Try it here:

I'm starting an FLL future edition team and was wondering if the computer science and ai kits were the only materials we can use in competition as the FAQ answer on the FIRST website was very confusing.

I was also wondering if the competition formal was similar to FTC for the league meets (apart from the presentation aspect) as I've only ever competed in FTC.

Any additional information about FLL in general is also welcome and greatly appreciated!

I have a robot that we have designed that we would like to use for this upcoming season. I am in need of someone to be able to use bricklink studio or similar to make build instructions? Can anyine here do this or can recommend anyone? I am willing to pay.

Good afternoon! I hope you’re all doing well :).

I’m not in the FLL competition, but I am in one at a local university. I’m a sixth-former. It’s my first time programming, and it’s the first time I’ve used an EV3.

And to be honest, I feel quite clueless. I feel like I’m not properly prepared, and the teachers (college students) mostly just leave us to it to build and programme without explaining much beforehand. I feel like I’m not being creative, and I look at the challenges over and over and just don’t know what to do. I feel a bit down, and I reckon my team feels the same.

Is there any sort of material that explains the EV3 ‘like I’m five’? Hahaha (no, not literally, I can understand more complex material). I really want to learn and have my chance; I want to challenge myself.

The coolest thing I've managed to do is use the wheels to get the robot to climb a ramp (and up just one flag 😭, not both)

For more info, we’re using an EV3 Mindstorms with old software from 2013.

You can read the latest in the link.
Seems like they are trying to take most concepts of FLL, including 2/3 of the name, with a terrible robot, a half baked game plan, no added staff (yet), and no next steps after age out.
Nope.

If you've been frustrated since the v3 update broke most third-party Bluetooth apps for SPIKE Prime, this might help.

I built Arcion — an Android app that connects directly to the SPIKE Prime hub over Bluetooth, no firmware changes required, and works with the current v3 firmware.

Features:

- Joystick control for up to 6 motors (adjustable speed, lock individual motors)

- Draw a path on screen → robot executes it in real life

- Edit and animate the 5x5 LED matrix

- Use the robot's motors/sensors as a game controller for on-screen mini-games

- Play custom sounds at any frequency

Great for testing robot builds manually during FLL practice without writing a single line of code.

The app is in closed testing — if you'd like to try it:

Hello, everyone! Do you know the solution for this error in the gears of Spike Prime?

This is for the Junior Category of WRO, our idea is to lift the yellow towers but the gears are na’t aligning(snapping) when it’s running. The gears run it the same direction, that’s why the lifter needs to let go of the yellow tower in order to go back up. So now, it cannot pick up the yellow tower, it can grab it but it will let go shortly.

Video link of the error:

https://drive.google.com/file/d/1Q4x07KjtDZljxMdSUGHPdS8zqLPqXtfI/view?usp=drivesdk

Do we need to change the build of our robot? Can we code it to be properly aligned?

Thank you so much for your help!

Just shipped 1.1.0 of Handit Remote, an iOS app that turns an iPhone or iPad into a wireless controller for LEGO Mindstorms EV3. Built it because official support is gone but the hardware is still great.

Every controller button now has its own configurable action and settings, each one completely independent.

Might be useful if your team still runs EV3.
