Hi all
I successfully follow your instructions about getting started with LPS :
https://wiki.bitcraze.io/doc:lps:index
Each anchor is set with the rignt number as anchors.
The crazyflie have new firmware. (anchor also new firmware)
In RViz the green dot don't move when I tried to move the Crazyflie
ROS display a error like the picture. And in the client, the date is normal.
And I use this command
It shows the error：
Code: Select all
ERROR: Cannot load message class for [bitcraze_lps_estimator/RangeArray]. Are your messages built?
Any help would be appreciated.

Hi,
The message from rostopic comes from fact that the workspace 'devel/setup.bash' has not been sourced in your terminal and maybe you are missing the catkin_make step. This file should be sourced in all the terminal you are using. One way is to add the line:
Code: Select all
source $HOME/catkin_ws/devel/setup.bash
in your ~/.bashrc. Also did you run catkin_make in your workspace after cloning all the projects?
For the visualisation it seems that not all the nodes are launched correctly. If the problem persist could you send an image of rtq_graph?

I modify it according to your prompts. And I did catkin_make before. The rtq_graph image is this?
I run rostopic again,but it's no response.

Maybe the crazyradio does't work,Normally,I use the "sudo cfclient" to run the cfclient,but I don't know how to run ros with super user.

I try to run ros with super user,and it worked. When I move the plane , the green point moved.
But now I try to control it with gamepad, the plane has no response.

You should setup udev to be able to run without superuser right. See there:
https://github.com/bitcraze/crazyflie-lib-python#linux
Can you describe a bit more your problem:
1 - What launchfile are you using
2 - Are you using an x-box gamepad
3 - What are you doing that does not work (ie. what button, ....)

Thanks for your reply.
1 - Actually I don't understand the launchfile you said.
2 - I am not using an x-box gamepad,but it recognized as a x-box in the cfclient.
3 - After run this command :
Code: Select all
roslaunch bitcraze_lps_estimator dwm_loc_ekf_hover.launch uri:=radio://0/80/250K x:=3 y:=2.3 z:=1.0
The RV worked , and I read the mapping，but the gamepad can't let it fly.
Thanks for your patience again.

Hi, thanks for the screenshot I might have an idea of what is going wrong.
Your laptop exposes an accelerometer as a joystick, and the launchfiles are setup to use the first joystick. In your case it is not the xbox gamepad but the laptop accelerometer.
You can try to change the used joystick with:
Code: Select all
roslaunch bitcraze_lps_estimator dwm_loc_ekf_hover.launch joy_dev:=/dev/input/js1 uri:=radio://0/80/250K x:=3 y:=2.3 z:=1.0
Best regards,
Arnaud
