RZR Release Time

Hi all, I am not sure if I have opened this topic in right subject or not, so sorry if I am wrong. I am working on my Master's Thesis right now and need to use a platform either built with BQ-Deck or (hopefully) RZR. As I followed from blog news, RZR should be out any time soon. So, my question is, ...

Re: LPS with Flow Deck and uneven terrain

Hi Carlos,

Would you mind to share with me how you manage to ignore Z data from UWB (I assume you did this, anyway I will be happy to learn what you did and how)? We are dealing with the same system now (UWB + Flow Deck) and I am searching for some ways to improve Z performance.

Thanks in advance,

Re: LPS System - Altitude Hold (z-position) Problem

Hi again, We have switched the system mode to TWR and conducted some tests. In the videos above, we placed crazyflie in the pre-measured points in the arena, and look for the overall estimated position of cf in addition to distance to every node. Firstly, here are the videos: https://www.youtube.com...

Re: LPS System - Altitude Hold (z-position) Problem

Hi kristoffer, After some trials, I want to explain you the situation we are in now. First of all, I upgraded the crazyflies' and nodes' firmwares to the latest one, I compiled and uploaded them. There is no connectivity issue right now, everything is fine and green, both in TWR and TDoA modes. As a...

LPS System - Altitude Hold (z-position) Problem

Hi all, We have LPS system installed in a room, exactly like in the starting guide, coordinates entered correctly (the bottom position of node 0 choosen to be origin, its coordinates seems like (0.0,0.0,0.15). There are 8 nodes, uploaded with the LPS Node Firmware (2018.01). For the time being, they...

Re: HITL and SITL for crazyflie

Hi, The multi-uav-final branch works fine for me with 5-6 cfs, but not 7. I compared my CPU (Intel® Core™ i7-6700HQ CPU @ 2.60GHz × 8 ) with yours and its an expected result I guess (I have same RAM size). When it comes to HITL, I wonder did you ever tried to fly multi cfs in HITL mode, or a single ...

Re: HITL and SITL for crazyflie

Hi,

We manage to work multi-uav-fix branch and in our case, it is working perfectly with 3 cfs but for 4 cfs, it sometimes crashes at some point. Yet multi cf performance is developed significantly, thank you again for this :D Apart from this, everything seems fine.

Hope to hear from you again

Re: HITL and SITL for crazyflie

I have tried the two quad case also, they work seamless except the consequences of increased computational load, you are right... Even so, thank you again for your valuable contribution. a small note: in the tutorial for two quad case, for the second console, port number will be "19951" instead of "...

Re: HITL and SITL for crazyflie

Hi again, I just want to let you know, about the multiple instances of SITL (to explain, in two separate terminals, executing "./cf2" command with different arguments), the second instance can not be opened, corresponding situation can be seen at attachments. Moreover, "./cf2" command does not seem ...
