problem using Turtlebot Interactive Markers

Hi everyone,

I'm trying to use interactive markers to move the turtlebot using Ros Electric version. The connexion with the turtlebot seems ok. The turtlebot service is running on the laptop. The dashboard is all green!!

I'm following the "TurtleBot Teleoperation Using Interactive Markers" tutorial. When I click on "interact" button on rviz, the interactive markers appear. But when I click on them to move the robot, only the camera moves. It's like I didn't change mode.

Has someone an idea of what is going wrong?

Thanks a lot for your help.

I suggest using "rostopic echo /cmd_vel" on the TurtleBot netbook to verify that when you're interacting, the messages are being received by the netbook. If they're not, you may need to make sure ROS_IP or ROS_HOSTNAME are set properly on the machine running rviz. (check here for more information)

Hey Barriere,

Were you able to figure this out. I am getting the same issue.

I tried "rostopic echo /cmd_vel", it give me correct values corresponding to motion. But the robot doesn't move. The circle is blue not green like you mentioned.

Thanks

Hi Ryan,

Thank you for your answer. But I don't think my problem is a communication problem between my desktop PC and the laptop.

I have made some basic test like "rostopic list" that succeed. I can teleop the turtlebot using my desktop pc keyboard. I can launch slam process and see result on rviz using my desktop PC. But I can't use the interactive marker.

As I said in my first post it's like nothing appends when I click on interact button. The markers appear but when I click on the 3D view it seems that we are still using "move camera" mode.

The only difference I can see with the tuto is that the circle marker is not green but blue. (Maybe color has a sense)

Thank you a lot for your help!

Hello,

I'm running the pr2 demo that is available for indigo and I'm getting the same issue. When I am in 'Interact' mode, I can put my cursor over the joint I want to control and the Interact Marker will appear, but if I try to click on one of the controls, all that happens is the camera moves.
