Limitations of using just one base station

[rampudia]

Hi I have two question about the lighthouse system:

1- What are the limitations in terms of range and accuracy for the positioning system for one crazyflie using just one base station?
2- Is it possible to program an automatic route using the crazy-lib-Python instead of moving it around with the Bitcraze client? If so where can I find an example? (I found https://github.com/bitcraze/crazyflie-l ... vr_grab.py butI don't understand what it is meant by 'grab' and if that changes things a lot)

Hi!

1. The maximum range of the base stations is around 5-6 meters. Usually the useful flight area is smaller as you need a bit of an angle to the sensors for them to receive the light, assuming the base station is mounted on one side of the area. The accuracy is not effected that much, but the robustness is better with two base stations since the Crazyflie will get more data. It will also handle tilt better as it is more likely to receive at least one base station when tilted.

2. Yes, you can. lighthouse_openvr_grab.py is not a good example for what you want to do. Check out https://github.com/bitcraze/crazyflie-l ... h_level.py, https://github.com/bitcraze/crazyflie-l ... equence.py and https://github.com/bitcraze/crazyflie-l ... er_demo.py instead.

Thank you! Very useful
