Re: Communication problems when running multiple Crazyflies

Thank you both for the replies, I really appreciate the help! I'll try time-slicing today and see if that helps me (I'm not using sensor data so hopefully this helps) For IM, that makes sense- I'll try to randomly space out my channels. As far as which flies are errant, this is fairly random between...

Communication problems when running multiple Crazyflies

Hello! (I have read multiple relevant posts on this forum, but haven't been able to solve my problems, so this isn't a repeated post) I am running 7 Crazyflies at a time, and I am using 7 Crazyradios, so I have 1 radio for each crazyflie. I developed my own trajectory tracking controller, which (usi...

Re: vertical control

My gains are very different than yours, but that is because I have 2 different nodes that handle the command-- the first one limits the thrust between some minimum (currently .7) and max (1), and the second one turns that into a number between 10,000 and 60,000 for the thrust command I would love to...

Re: vertical control

My oscillations seem to be around 4 cm, which isn't a big number, but it's not smooth flight at all. (attached plot of the vertical position over time, with the desired position being at .4) I use an OptiTrack system with 120 Hz update rate, and I am also using ROS directly installed on a machine wi...

vertical control

I'm working with crazyflies in a motion capture area, and I've implemented both -PID control to travel to waypoints, as well as -trajectory tracking to travel in certain paths. However, I'm having trouble getting the vertical stability. Currently, my trajectory tracking deals with x/y (pitch/roll) c...
