What is it about?

FLS Battlebots in cooperation with Maker Faire has prepared a combat robot tournament for you, in which original robotic constructions will be presented in a special arena, showing what can be created with the help of modern technologies, 3D printing, electronics, and skilled hands. The robots will face off in dynamic and often noisy matches full of surprises, during which it will never be clear in advance who will be the winner. The competition consists of building your own remote-controlled machines, which compete in the arena in one-on-one battles, with the goal of pushing your opponent out of the arena or simply knocking them out of commission. If you come as a spectator, you can look forward not only to the battles themselves, but also to the opportunity to see the robots up close, watch them being repaired between matches, have their creators explain how the robots work, and even try controlling a robot yourself. An unforgettable experience awaits you, where you can cheer on your favorites, be inspired, and get to know the world of combat robots up close.

Registration

Registration is done on a team basis. Each team can have up to 5 members and 5 robots. The number of robots is independent of the number of team members or drivers. Robots from the same team cannot fight each other (this rule may not apply if there are only a few robots registered).

Registration OPEN!

The hole can be covered with panels on all sides. During the tournament, only the side facing the center of the arena will be covered. Around the hole at the bottom, there is a box into which the robots can fall. These robots can be removed through a small door on the wall of the box. The arena also includes a timer for counting down the time and lighting. wall of the box.

Participants are expected to arrive at the tournament by 9:30 a.m. at the latest and bring their belongings to the hall, where tables and chairs will be provided for them. Organizational details will be specified approximately one week before the festival. Upon arrival, participants must report to the organizer and undergo a technical inspection during the tent period, where the robot must comply with the following:

• weight – 150 g (or 225 or 300 g)
• dimensions – must fit into a cube measuring 15 cm x 15 cm x unlimited
• failsafe – weapon and drive shutdown after loss of signal from the control
• color coding of the off position on slide switches (a visible dot at the off position is sufficient)
• weapon safety (in the case of rotating or sharp weapons)

Once the robot has passed the technical inspection, it is eligible to participate in the tournament. Even after the inspection, it is possible to make adjustments to the robot, but the same requirements must still be met. The organizer may perform an inspection at any time and may disqualify the robot if the requirements are not met. Before the first round, the remaining time can be used, for example, to get to know other builders, inspect competing robots, or help with organizational matters

Matches are paired using the Swiss system, meaning that the highest-ranked robots compete against each other. However, it is not possible to compete against the same robot twice (except in the final matches and in cases where there are more rounds than possible pairing combinations). After the matches, there is always a break to recharge batteries or make repairs and improvements. The winner is decided based on points. If some robots have the same number of points and it is not possible to decide the medal positions, one or more final matches will be played. In the event of a tie between the top three robots, the robots will compete against each other at the same time.

Things to remember

• Carefully study the tournament rules.
• Prepare spare parts and tools for repairs between matches. Bring your own extension cords.
• Pay attention to safety – not only your own, but also that of others.
• Follow the schedule and be ready for your matches on time.
• Respect the decisions of the referees and organizers.
