The field
- At least 11 m long, 5 m wide and 2,5 m high and a safety net. The field ground is a dark coloured carpet or rubber mat.
- 4 walls (obstacles) with at least 1500×1000 mm (width × height) rectangular holes at different heights. Maximum size of a wall is 1800×2500 mm. The colour of the walls is dark brown or black.
- a white 50 mm indicative line on the field.
The robot
- Fly at the height of 0,3 - 3 m. Can have stiff wings, rotors, moving wings or an airship-like design. A maximum speed of 10 m/s.
- Weight up to 2 kg and its dimensions max 80×80×80 cm3.
- Maximum of four active and/or passive navigation devices can be used. Navigation
devices must be placed in the corners of the field.
The competition
- Max 3 people

Technologies
- Wi-Fi-based positioning system (WPS)
- Bluetooth (ver 5.1 *does* specify AoA and AoD )
- Long Range and Direction Finding Multiprotocol Module Suitable for BLE / Thread / Zigbee / ANT+ / NFC applications with MCU and Antenna https://www.insightsip.com/products/bluetooth-le-modules/isp1907 https://www.insightsip.com/fichiers_insightsip/pdf/ble/ISP1907/isp_aoa_AN210401.pdf
- 12 Antennas should be used? https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/direction_finding_central/README.html
- Needs an antenna array? SmartBond TINY Bluetooth Low Energy Module https://www.renesas.com/en/products/da14531mod?language=en
- Choke point concepts (RFID / NFC systems)
- RFID's range about 2 or 3 m absolute max.
- Grid concepts
- Angle of arrival
- Time of arrival
- Received signal strength indication
- Radio frequency identification[16] (RFID): passive tags are very cost-effective, but do not support any metrics
- Ultra-wideband (UWB): reduced interference with other devices. DW1000 and DW3000 chips.
- a wide bandwidth (>500 MHz)
- pulse-position or time modulation
- Indoor localization using ESP32_UWB (DW1000) tags and anchors https://github.com/jremington/UWB-Indoor-Localization_Arduino/blob/main/README.md https://www.makerfabs.com/esp32-uwb-ultra-wideband.html
- Ardupilot and UWB https://discuss.ardupilot.org/t/indoor-positioning-with-ardupilot-based-on-uwb-modules/28819
- Test https://www.instructables.com/ESP32-UWB-Indoor-Positioning-Test/
- https://github.com/KunYi/esp32-uwb-positioning-system (ESP32 boards with DW3000 UWB module)
- Infrared: previously included in most mobile devices
- Gen2IR (second generation infrared)
- Visible light communication (VLC), as LiFi: can use existing lighting systems
- Ultrasound: waves move very slowly, which results in much higher accuracy
- IR emitter & receiver
- RSSI will not give very good results even in an open space (https://forum.arduino.cc/t/indoor-positioning-system-using-arduino/242161/2)
