ROS crazyflie_server

Post by ciccio » Tue Apr 10, 2018 7:43 am

Hi Crazyflie team,

i've installed ROS kinetic on Ubuntu 16.04 LTE as suggested by https://wiki.bitcraze.io/doc:lps:ros. I've tried to run roslaunch bitcraze_lps_estimator dwm_loc_ekf_hover.launch uri:=radio://0/80/250K x:=3 y:=2.3 z:=1.0 changing appropriately parameters. I have already connected the crazyflie with the client several times and it recognizes all the anchors but when we start the command it starts RViz but the terminal gives me this error: the crazyflie_server has stopped working.

Rvitz can not display the crazyflie in the area, a green dot should appear, as can be seen in the image below.
It also reports errors in RobotModel and Axes

How can i solve these issues?

I have seen similar problem when the URI is not correct, are you sure of the radio URI you are using is correct? Are the LEDs on the crazyradio blinking green or red briefly when you start the launchfile?
