joy_node runs fine but teleop_node causes segmentation fault. Also tried it with joystick_teleop_node and it does the same thing. I have the Husky simulator running in Gazebo and Rviz but I wanted to control Husky with an Xbox controller and I can't get these other nodes to work. I have Ubuntu 14.4 and am using ROS Indigo.
If you don't want to diagnose the problem, but rather work-around it, then I'd recommend using teleop_twist_joy. It's a standard pkg for joystick teleoperation.
Unless you want to educate yourself, writing yet another teleop node seems unnecessary.
Going carefully trough the joystick tutorials took care of the problem. Those are excellent!

Which
joystick_teleop_nodeare you referring to specifically?The one from utexas bwi repository. I tried this one because it had worked for me last year on this same laptop. I tried these two nodes without Gazebo and Rviz loaded but it still faulted.
Could I ask you to please always include either a reference or a link to the specific pkg(s) you are using?
As for
SEGFAULTs, agdbbacktrace is almost an obligation. Could you add one? Can't guarantee that will help, but it's a good start.I will try following this tutorial and see what happens. http://wiki.ros.org/joy/Tutorials/Wri...
So far I don't have experience with gdb backtrace.
Does
joystick_teleop_nodeSEGFAULTwhen you run it with justjoybut without any of the other nodes / programs (ie: Gazebo and RViz)?
