In this use case you’ll see TeraRanger Tower and TeraRanger Evo enabling obstacle avoidance for indoor drone flight (GPS-denied). A single TeraRanger Evo controls the altitude of the drone whilst TeraRanger Tower prevents the drone from flying into static and dynamic obstacles.
This configuration is compatible with Pixhawk running ArduCopter. See our detailed post here for full setup details and instructions.
