Laser ranging
Measure distances to objects all round
How it works
The Multi-ranger deck measures the distance to the nearest surface in five directions around the Crazyflie® 2.x - front, back, left, right, and up - with millimeter precision up to 4 meters.
The Multi-ranger can also be used as a starting point for experimenting with mapping and exploration.
Note: The deck provides sensor data only. No collision avoidance or obstacle reaction is enabled by default. For examples of how to use the sensor data, see the Multi-ranger examples in the crazyflie-demos repository.
