Lighthouse Positioning Deck

The Lighthouse deck uses the HTC Vive base stations (aka Lighthouse) to achieve high precision positioning. The deck has 4 receivers which gives position and will in the future also give pose of the Crazyflie.

The hardware supports both Lighthouse V1 and V2 base stations, but with the current firmware only the V1 base stations are supported. The firmware is under heavy development and V2 support will soon be added.

The position and pose is calculated directly in the Crazyflie, which makes it possible to create fully autonomous systems without external communication.

Since this is an early access product the main documentation is on the wiki:

• Hardware documentation
• System and getting started documentation

Below is a video of 3 Crazyflie 2.1 flying with the Lighthouse deck and V1 base stations using our python MotionCommander API.
