Hello everyone,
When I run rviz under Kinetic on minipc, it show me this:
rosrun rviz rviz
/opt/ros/kinetic/lib/rviz/rviz: symbol lookup error: /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: undefined symbol: _ZN24QAbstractDeclarativeData15setWidgetParentE
It seems there are some wrong with Qt.
I had saw some questions just like this,but get nothing to solve this.
ldd /opt/ros/kinetic/lib/librviz.so | grep Qt
libQt5Widgets.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 (0x00007f936b63f000)
libQt5Gui.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5 (0x00007f9369640000)
libQt5Core.so.5 => /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 (0x00007f9368f9a000)
there is no wrong with the librviz,can someone tell me how to solve this?
thx.

Finger positions of kinova arm does not update in RViz
Dear ROS community,
I am using kinova-ros package installed from source (kinova-driver release 1.2.1). The finger positions of kinova arm does not update in Rviz.
But both joint_state and finger positions topics are published. And I am able to controller each fingers with the script "fingers_action_client.py".
rosrun kinova_demo fingers_action_client.py j2n6s300 -r -v percent -100 -100 100

Gmapping doesn't notice robot is stuck on Gazebo
Hello !
I am trying to do slam with gmapping on a custom robot simulated on Gazebo. My robot has a squared base, two wheel at the front, one caster at the back, a laser scan(similar to RpLidar) and an IMU. Odom is get thank to diff_drive_controller.
At first, I noticed that my odom was awful. For example, when rotating the robot, the laser scan was totally wrong and didn't match the walls previoulsy seen. So I used robot_pose_efk to fuse IMU and odom data.
Now, the results are very satisfaying : the new scans match up the old ones when rotating the robot and I am able to perform SLAM on a "complexe" world. Troubles come when my robot get stucks somewhere. For example, if I use teleop to make the robot moving against the wall, rviz doesn't see that at all. It will act as the robot is continuing its path normally, though it is completely stuck on gazebo. As a result, my map become totally wrong.
My question is : how can I avoid this ? I thought fusing IMU and odom were going to be sufficient, but apparently I was wrong. So what then ? Adding bumpers or other sensors to detect a collision with a wall ? Can I achieve that with my already implemented laser scan ?
Here's my lauch file to start simulation :

How to make a maker parallel to a vector
Hi there, I'm trying to define a marker(cylinder) which connects two known frames visualized in rviz.
I want this maker point from one frame to the other frame...
And the what I've gotten now is the transform between these two known frames. The first thing I come up with is make this marker parallel to this transform vector. But I was failed to implement this idea.
I would be appreciated if you can give some Pseudo Code (and the function names that will be perfect).
OR, maybe a greater idea to make this thing up.
Code_of_mine
marker.pose.position.x = ls_transform.getOrigin().x()/2;
marker.pose.position.y = ls_transform.getOrigin().y()/2;
marker.pose.position.z = ls_transform.getOrigin().z()/2;
marker.pose.orientation.x = ls_transform.getRotation().x();
marker.pose.orientation.y = ls_transform.getRotation().y();
marker.pose.orientation.z = ls_transform.getRotation().z();
marker.pose.orientation.w = ls_transform.getRotation().w();
And the marker is put in the middle of two frame, but the angle is not correct. (Sorry I can't load up my picture cause I don't got enough points...)
P.S. I set the marker_frame follow the one of two frames(which means origin = 0). When I set the marker_frame is my first frame, problem still occur.

How to show marker with utf8 in RViz
Hello everyone,
I wanna show a TEXT_VIEW_FACING Marker in RViz with utf-8 encoding, but Marker doesn't show in RViz, new_mark.text is a std::string value and print in terminal.
std::cout << "it -> first: " << it.first << std::endl;

Turtlebot depth image not showing in image_view
Hello,
I want to try some opencv algorithms with depth images from the turtlebot1 (create base). I want to save them for later use because of the complexity of modifying and remaking a node.
We have our Turtlebot started with Turtlebot_bringup minimal.launch and turtlebot_bringup 3dsensor.launch. RVIZ is currently showing */camera/depth_registered/image_raw* (which dont look as detailed as I imagined looking at the IR image) but not any */camera/depth/* topic. I tried `rostopic hz /camera/depth/image_raw` but it is not publishing.
`rosrun image_view image_view image:=/camera/depth_registered/image_raw` says:
> Unable to convert '16UC1' image to bgr8: '[16UC1] is not a color format. but [bgr8] is. The conversion does not make sense'
Can I somehow easily save these images for later processing?

Isolated and non-isolated ament build command behave differently
I'm building ros2 from source using this [dockerfile](https://gitlab.com/kunaltyagi/dockerfiles/snippets/1723360). This is outcome of [this question](https://answers.ros.org/question/293443/docker-ament-command-not-found/). TLDR: the additional packages recommended on [the wiki](https://github.com/ros2/ros2/wiki/Linux-Development-Setup) plus `ros2:ardent-basic` image.
Isolated build complete successfully, but non-isolated builds fail (specifically `rviz_rendering` fails due to missing `RenderSystems/GL/OgreGLPlugin.h`). Apart from this package, no other package has such an issue. Ideally, I'd expect the non-isolated build to not fail for missing header files if the isolated build doesn't (as @marguedas pointed it out on [this post](https://discourse.ros.org/t/isolated-in-docker-image/3504/2?u=tyagikunal)).
To reproduce, use the docker image and run:
cd
mkdir -p ros2/src
wget https://raw.githubusercontent/ros2/ros2/release-latest/ros2.repos
vcs-import src < ros2.repos
src/ament/ament_tools/scripts/ament.py build --build-tests --symlink-install

Moveit teleoperation of 3DOF arm with 3D mouse
In short, I want to control the endeffector of my 3DOF arm in cartesian space with a 3D mouse. (Very similar to https://answers.ros.org/question/226958/best-way-to-use-moveit-for-teleoperation/ , only that my robot arm only has 3 DOF)
What I got working so far:
- Moveit configuration generated
- I can move the interactive marker, plan and execute paths in Rviz
- I can move the arm into goal poses with orientation from python
Now my problem seems to be that due to the lack of DOFs I always need the orientation values for the EEF in the moveit interface to plan poses that I want my endeffector to end up in.
I attempted to
- generate an IKFast solver using the Translation3D configuration/parameter => compiles, works, however still requires orientation?!
- play with the tolerance as mentioned in https://bitbucket.org/traclabs/trac_ik/issues/30/use-trac_ik_plugin-with-3dof-robot (changed the value in the all_close() function)
- tried to set position_only_ik: True in kinematics.yaml
- took a look at https://github.com/ros-planning/moveit/issues/548 however I dont want any EEF rotation (also can set it), just an EEF x,y,z position
Now my question is: How can I get moveit to plan paths to EEF positions without needing to specify any orientation values?

How to control the 'ghost' in MoveIt's Rviz MotionPlanning plugin from code?
Hi guys,
I am fairly new to MoveIt's MotionPlanning API. When adding the MotionPlanning plugin to rviz, a 'ghost' of the controlled robot arm is spawned, along with an interactive marker that can be used to drag it around. Is there also a way to control the ghost (the end effector and the joints) in a cpp node? Can the joint states of this ghost be read out somewhere?
Cheers,
