What is the Czech Combat Robot League (CCRL)?

The Czech Combat Robot League (CCRL) is a series of combat robot tournaments run by FLS Battlebots, a robotics community from Pilsen (Plzeň). In the 2026 season the league held six rounds in Pilsen, Karlovy Vary, Prague, České Budějovice and Brno, four of them as part of a Maker Faire. This calendar also lists tournaments in other countries, so you can find events across Europe on the map and in the list above, filtered by weight class and country.

Weight classes

Each robot fights only against robots of the same weight class. The CCRL recognises four classes:

  • Antweight – up to 150 g, must fit a 15 × 15 cm base (plus PLANT, an antweight made only of plastic)
  • Beetleweight – up to 1.5 kg, spinning weapons limited to 1 kJ
  • Raptorweight – up to 6 kg (called hobbyweight in the USA), rules in preparation
  • Featherweight – up to 13.6 kg, rules in preparation

Robots with non-traditional movement get a 50% weight bonus and true walkers 100%. More in weight categories.

How to take part

Dates, venues and details are on each tournament page. Before you build, make sure there are tournaments for your chosen weight class in your area, and read the antweight rules or beetleweight rules. Announce all your robot's configurations before the competition starts, and if you are unsure whether your weapon complies, contact the organiser before the tournament.

What happens at a tournament

Before the competition, organisers check every robot: weight, dimensions or weapon energy, power switch, failsafe, weapon lock and covered sharp edges. Matches take place in a closed arena and normally last 3 minutes. A robot loses if it falls into the pit, cannot move during a 10-second count or gives up; if a winner must be decided, three judges score weapon effectiveness, aggression and control. At Maker Faire rounds visitors can also meet the builders and try driving a robot. Read more in how combat robot tournaments work.
