Re: Pose topic using Crazyswarm

I am referring to the topic crazyflie/pose. When I used lps-ros with crazyflie_ros I could see the pose of the cf with it. Now, when I launch hover_swarm.launch I can see the following topics and services: ROSTOPIC LIST: /cf4/cmd_full_state /cf4/cmd_position /cf4/cmd_stop /clicked_point /diagnostics...

Pose topic using Crazyswarm

Hi everyone, Since Whoenig recommended us to use the Crazyswarm package instead of the crazyflie_ros package to fly more than one cf2 (https://forum.bitcraze.io/viewtopic.php?f=16&t=3362) we have been flying properly with it. However, we have a doubt about the information it offers over ROS. In cont...

Take off error using dwm_loc_ekf_swarm_hover.launch

Hi, I am Agustín and in my research group we are testing swarm missions with LPS in TDoA2 mode and 8 anchors. Now, we are testing with 2 crazyflies 2.0 launching the dwm_loc_ekf_swarm_hover.launch commenting the part of the code related to the 3 last cfs (the launch by default is for 5 cfs). Our pro...

Re: cmd_vel in crazyflie_controller_bridge.py

Ok, thank you. We remain attentive for new changes. It would be very beneficial for our research. According to the crazyradio, we are trying to fly 3 cf2 using 1 cr. However, one of them never takes off. We have tried to add a second cr but do not get it to work properly.Although both cr are plugged...

Re: cmd_vel in crazyflie_controller_bridge.py

Thank you for your answer!! We are already flying two cf2 in mode TDoA2 with 8 anchors (the guide recommends to use this mode for 8 anchors). Now, we're using the crazyflie_controller_bridge.py with more accuracy than ever. At the moment, we're sending position setpoints to the topic cmd_vel, but we...

cmd_vel in crazyflie_controller_bridge.py

Hello, My name is Agustín Ramos and I am a researcher at the University of Seville (Spain) in the group of Robotics, Vision and Control. Since a month ago we are testing the Loco Positioning System with 6 nodes in TWR mode and with one cf2. We are using ROS Kinetic, Ubuntu 16.04 and the drivers lps-...
