The provided information relates to the specifics of the competition.

Arena size: 5.4 m x 7.2m, max height 2m

Obstacles: Obstacles will be pipes of different height and diameter (~10cm) as illustrated in the below picture. 

Marker size: The marker size will be 10×10 cm, and it should be visible from a distance around 70 cm (grayscale image, camera streamed with 3 FPS)

Number of markers in the arena: The markers will be between 5 to 10, however, the exact number of markers will be announced immediately before a scheduled run

Crazyflie team size: 3 or 4 Crazyflies

Pose feedback: Optitrack

Connectivity rules: same as for the simulation, communication range: tentatively 2 to 3 meters (exact number will be provided before the competition, depends on the size of the Optitrack coverage area)

Map layout: different layouts will be used, octomap will be provided at runtime

Flight restrictions:
Takeoff rate: 0.2 m/s
Max velocity: 0.9 m/s
Minimal xy distance between UAVs: 0.3m (no flying Crazyflies above other Crazyflies regardless of height difference)

Battery recharging procedure:
As soon as one Crazyflie reaches the critical battery level, all UAVs must return to base. Batteries can then be exchanged by team members, and the mission can continue.

​Run ending procedure:
All UAVs must return to the base and land, team leader then declares that the run is over.

Competition timeline: 
Tuesday May 13: arena setup by the competition organizers, software installation and integration workshop for teams
Wednesday May 14: practice day (slot duration and schedule will be announced on Tuesday)
Thursday May 15: competition day (slot duration and schedule will be announce on Wednesday)
Thursday May 15 evening: gala dinner with the competition results announcement

Software: 
We are working on preparing the Docker image and container, the procedure for running your solutions should be similar to the simulation stage. We kindly ask for your patience, as I already mentioned we are working hard on testing the Crazyflies, camera streams and everything else. However, if you have urgent questions, feel free to contact us.
