Laser ranging
Adds the possibility to fly with precise height control.
How it works
The Z-ranger deck V2 uses a laser sensor to measure the distance to the ground. The deck enables the Crazyflie® to automatically maintain a constant distance to the objects under it when flying in automatic mode. Over a floor it will stay on the same height, but will follow the shape of a stair case up or down when going on adventures.
The maximum range for the ranger is 4 meters.
