Error When running base drive in RVIZ

abdksyed opened this issue 4 years ago · comments

Hi,
When I am running the command
roslaunch champ_config bringup.launch rviz:=true
I am getting this error, and the RVIZ GUI is opening up, but I am unable to perform any task like moving forward or turning etc using keyboard controls of (u,i,o,j......).

Can you help me check the following:

Have you build the workspace:

cd ~/<your_ws>/ && catkin_make

You have sourced the workspace before running the demos:

source ~/<your_ws>/devel/setup.bash

You have yocs_velocity_smoother in your 'src' folder

cd ~/<your_ws>/src
git clone https://github.com/chvmp/yocs_velocity_smoother
cd ..
catkin_make

I tried reinstalling everything from scratch, and it's working fine now.
Thanks for the help anyways.

I am facing a similar issue without any explicit error messages on the terminal.

I am unable to move the bot using teleop.launch.
I double-checked and followed the steps mentioned earlier by grassjelly. Even re-installing wasn't of help.
After firing up teleop.launch, performing rostopic echo /cmd_vel displays nothing. Likewise for rostopic echo \body_pose.
Any suggestions would be greatly appreciated!

After launching both terminals (teleop and rviz), press and HOLD the key in the controls terminal (U or I or O), the bot will move

It did! Thanks a lot!

It seems like the warning in the screenshot are not error messages but related to velocities that meant sensors are not getting proper input to move

Haha right! I spent a long time going through the code imagining that those warnings caused the bot to not move. Can we display a more explicit message in the teleop.launch to keep the key pressed?

The last line gave me the impression that it's constantly publishing to the velocity topics.

lol! Yes, you just need to follow those instructions. In the code there is a docstring for this message and you can make changes locally by adding the statement. But you can check with the author of the GitHub if you want to publish it .
