Prepare for World Robot Olympiad robotics competition. The complete guide

This World Robot Olympiad guide is the single greatest resource to prepare for the competition. The guide aims to make it easier for mentors, teams, and team members to successfully get up to speed, participate and advance in the World Robot Olympiad competitions. WRO is similar to FLL competitions, as LEGO robots are used. But apart from that, it is a completely different competition with specific categories and challenges. We've published 300+ robots, 1500+ attachments/constructions, 50+ courses, and 500+ tutorials for teams to get started and then advance to building consistent and reliable robots. From our point of view, WRO is much more about programming and doing fewer more complex tasks and many simple tasks where competitors are limited by time.

Introduction - Why this guide?

We are mentors, judges, teachers, professional engineers, and software developers. Through the years, we've gathered a lot of experience in robotics competitions, mainly FLL and WRO, but also in Sumo, FTC, FRC, First Global, and many others. We've been helping teams for the last 15 years. At FLLCasts, we share courses, robot constructions, attachments, and programs that demonstrate how different missions could be accomplished and how you can have complete control over your robot. We try to build resources that are suitable for both getting started and building consistent and reliable robots. Note that we do not share solutions for the current seasons. That is against our rules. We share the principles by which various missions could be accomplished and how similar missions were accomplished in the past. You have all the information in one place.

WRO is a challenging journey with three major categories - Elementary, Junior, and Senior. FLLCasts has helped tens of thousands of students build consistent robots that accomplish complex missions. You can find topics like Line Following and Aligning, as well as more advanced programming, Box Robots, use of rubber bands. The goal is to have consistent behavior of the robot. We are your partner with all the experience and knowledge that we have, and we will guide you through the process of learning and accomplishing the missions.

This is the current season of the competition and you are reading this guide because you would like to prepare better for the robot game, have lots of fun and advance to the next rounds.

The guide will help you with developing the programs and the mechanism. We will also help you with building reliable and consistent robots. But before any of this, you should get familiar with the season, its missions, and rules.

Where to start?

In the beginning, FLLCasts was built around FLL, and then it grew to WRO and more similar competitions. Start with the FIRST LEGO League Robot Game. The complete guide. We built the FLL guide before WRO, and we have most of the information structured there.

After you get familiar with it, proceed to the specific courses you need for your specific set.

Both EV3 and NXT are no longer supported by LEGO. Although LEGO does not sell these sets anymore, almost all of the constructions that were previously built with EV3 and NXT could be reused. After all, they are just LEGO parts with different electronics.

If you don't have a field from previous years, you could use the FLLCasts Off-Season course to work on general competitions missions with a single LEGO Mindstorms EV3 set.


Learn from previous competitions

"Smart people learn from their mistakes. Wise people learn from everywhere they can"

When you prepare for the current WRO season, there is nothing better than having all the experience from participating in previous competitions. But this is not possible, because previous competitions are...well...previous. You are forming the team now. It's a new team, and all the experience from previous years is gone.

Luckily we've recorded and explained our solutions to some of the World Robot Olympiad (WRO) challenges. Start with the most recent ones and then go back to the missions and their solutions and reviews. Learn how a similar mission was approached in the past. As you already have this toolbox of knowledge, you can now decide which attachments and robots to modify and use for the current season.

Testimonials

FLL Casts has great content! Our team is composed of 4th-5th grade students, and we found the information you provided on topics like Box robots *extremely* helpful. Also, the tips on how to follow a line and other types of intelligent robot control are invaluable. There is no resource like FLL Casts out there for a new team of young kids who are eager and excited to learn the EV3. Neither Lego nor First Lego League provides *any* step-by-step instruction from both a mechanical and programming point of view - which seems like a huge miss.

I want to thank you for your programs, they were so valuable in having a FLL team move forward.

First of all, you have produced a page with very nice content. Thank you very much. Since I participated in the FLL contest, I was using your web page in robot design and basically to learn the codes. I chose not to participate in the competition this year. I am thinking of rejoining your platform when I decide to join the competition again.
