Optical navigation
Enable positioning in the air with optical motion detection.
How it works
The Flow deck V2 gives the Crazyflie® 2.x the ability to understand when it’s moving in any direction. The VL53L1x ToF sensor measures the distance to the ground with high precision and the PMW3901 optical flow sensor measures movements in relation to the ground. This creates a flying 3D robot that can be pre-programmed to fly distances in any direction or act as an aid for beginners where it creates a very stable flying platform.

Development
Firmware intergration
The flowdeck provides optical flow and height measurements which are fused in the Extended Kalman Filter of the Crazyflie Firmware.
Hardware Hacks
We did a light painting with the flowdeck together the LED-ring deck . Check the project on hackster.io
