Re: implementing collision avoidance in FW

OK , I have done alot of testing and have some success! I succeeded in making the CF stop whenever it encounters obstacles. But it is doing it with a high-level position command , so it works when I use a high-level controller. This required changing the go_to function in crtp_commander_high_level.c...

Re: implementing collision avoidance in FW

I found crtpCommanderHighLevelGetSetpoint https://github.com/bitcraze/crazyflie-firmware-experimental/blob/857c1e64ec91eaa5b0e2799447dffcb75343ea27/src/modules/src/commander.c#L87 I assume it allows polling the current go_to setpoint. but if I want to pass all commands through my code I will have to...

Re: implementing collision avoidance in FW

Thanks! it works! I was focused on the compiling and running I missed this functionality in the code. regarding your comment on high level control, from my experience you can send low level set points to a drone running high level controller, but after the command finishes executing the drone will r...

Re: implementing collision avoidance in FW

Hi again! I tried to follow the instructions. for the first method (push.c as a "virtual deck") first I tried cloning the proper branch of crazyflie-experimental and building it, but there were many errors.

Re: implementing collision avoidance in FW

thank you very much! I have searched for few hours and found no similar code on the web, academic articles or in the forums.
I will try to implement using a "virtual deck" method first, as I assume it has lower chance of creating bugs.
report here when I have progress

implementing collision avoidance in FW

Hello are you aware of anyone who implemented collision avoidance in firmware? I am using the mellinger controller so I would prefer to implement on it. I tried running collision avoidance routine on the PC but sometimes it has lag or communication glitches and doesn't work well. even pointers on an...

flow deck outlier filter - after update to new FW version

I'm moving at slow speeds 0.15m/s using mellinger controller. when logging the motion.deltaX , motion.deltaY parameters (raw data from flow camera) I no...

Re: number of anchors needed

thank you for the reply tobias. I researched the topic but missed the part about accuracy. Now I read it again. I would love if you had some more details , even for a test case. the documentation refers to a room about 3*6 meters in size, 2.6 meters height. what accuracy can I expect in this case wi...
