Joy node doesn't work well [closed]

Hi everybody!

I am trying to use an Xbox joystick with the joy node in a virtual machine. Although I've checked the correct joystick signals reception as shown in http://www.ros.org/wiki/joy/Tutorials/ConfiguringALinuxJoystick (link text) with sudo jstest /dev/input/js1; I've changed correctly the permissions; and I've set the ros param to the correct device (js1), but the node has problems to publish the data. If I run the test as the tutorial tells, it takes some minutes before the first rostopic echo /joy received. Once I receive the echo, the values seems to be correct. This problem increases when I launch that joy node with a several other nodes, in that case, I never get the echo response of the /joy topic.

I am running Ubuntu 12.04LTS with ROS fuerte on a virtual machine using VirtualBox, and It doesn't seems to have any processor, I/O, or RAM problems (I run it together with Gazebo, rviz, etc.).

Thank you!

When you say it doesn't seem to have any processor, I/O or RAM problems, you mean nothing else is slow? If all that is happening is the /joy topic takes long to get published to, I would assume it is a problem of hardware virtualization and/or excessive swapping. Could you try it outside the VM?

Testing the joystick with a test like "jstest", running on the virtual machine, everything works fine. Using ROS, everything seems to work fine, even gazebo and graphic rendering programs. The problem starts using /joy node. (Other nodes or programs work fine running at the same time than /joy).

Finally I got the solution without finding the failure...

I've reinstalled the whole system again and now it seems to work.

In order to change the ros param, you have to go to the xbox360_teleop.launch and add < param name="dev" value="/dev/input/js1"/ > to the joy node. <node pkg="joy" type="joy_node" name="joystick"/>
