It's also probably because it's a lot easier to use an off-the-shelf commercial drone than to build/modify one (from a researcher's perspective), and commercial drones typically already have cameras than can be accessed through their SDKs.
Also, off-the-shelf depth sensors can add a lot of weight to the drone. It might still be possible to fly with the extra weight, but now the drone will be more sluggish and fragile. It would be great if commercial drones had a built-in depth sensor.
Distance sensors such as sonar and proximity sensors are usually very noisy and they are susceptible to interference (if you use more than one).
- otto_ortega 9y agoThose drones are perfectly able to lift a couple of pounds according to their specs. The other reason you mentioned about not wanting to customize it is more likely.
- alexleegk 9y agoYes, but what I was trying to get to is that even if the drone can handle the payload, the drone becomes too heavy to crash safely, and it might break more easily (after falling down with all that extra weight).
- blt 9y agoVision-based navigation is ultimately more interesting for robotics. Structured light depth cameras don't work in bright sunlight and aren't useful for long range perception. They also use more battery power for the light source.
