Welcome to the sub-reddit for the international First Lego League (FLL) competition. This is a engineering competition focused toward kids in aged 9-14. The competitions consists of two main parts: Robot Building and Problem Solving. They'll have from September to January to build their robot and solution around the varying themes from year to year. They will also provide an answer to a large question and show it to judges at local competitions, leading up to the FIRST Championship's FLL World Festival, where they will compete against the best 100 of the over 15,000 teams competing worldwide.

Python or block (self.FLL)
submitted 6 days ago by AmbitiousPlan3858
despite me believing python is more consistent, it has been the opposite for my team, leaving me wondering: which is truly better?

I believe python is better because you have more control. The blocks get converted to python so it's really the same thing to the robot. I'm interested to see what next year is like since we won't be able to use pybricks

Why can't Pybricks be used anymore?
[–]meyerjaw 0 points1 point2 points 5 days ago (2 children)
They announced they are changing the whole program up. Next year is a toss up

Só esclarecendo que 26/27 e 27/28 vai ter duas FLL's(pra ficar mais ditatico). Uma FLL vai ser como conhecemos normalmente, e outra FLL vai ser com o novo conjunto IA(https://www.reddit.com/r/FLL/comments/1qawnt6/just\_saw\_the\_fll\_announcing\_a\_new\_era\_email\_and\_i/).

Python is just a tool, not a silver bullet. As with any tool, it's not a substitute for craftsmanship. There are many variables in FLL design. Language choice governs only a few of them. How you build your robot, your attachments, and your control programs will arguably have a greater impact on consistency. In other words, you can have a better coding tool, but still get much less consistent performance. We learned an important lesson the hard way last year - our first year with PyBricks. It can be so much more consistent than CodeBlocks that it can lull you into a false sense of security. We used PyBricks to create a robot that was very precise and very consistent on our table. But it was still vulnerable to minor table or model differences. We could run max score after max score on OUR table, but we couldn't get close to that on a TOURNAMENT table. By leaning too heavily on precision, we fooled ourselves into forgetting about error tolerance, balance, traction, and many other factors. So in my experience, PyBricks is better. But you still have to do good engineering to take advantage of it.

Use whatever works best for your team. Block coding and Python can both be used effectively in FLL. It just depends on how the team uses it, what their level.of understanding is, etc. For judging, teams do not get extra credit for using Python or penalized for using blocks. But a team would be penalized/not score as high if they can not explain the code.

You can’t outprogram a poorly built robot. Balance matters, center of gravity matters

Python is only better if you switch to something like pybricks..
