I am setting up a ps3 joystick, according to the ps3joy tutorial - WritingTeleopNode.

I have followed the instructions and built the sample code for the teleop_turtle_joy.cpp.

I also created the sample launch file. However, I am not sure how to run this. When I try: roslaunch learning_ps3joy turtleps3joy.launch

I get the error:

ERROR: cannot launch node of type [ps3joy/ps3_joy_node]: Cannot locate node of type [ps3_joy_node] in package [ps3joy]
ERROR: cannot launch node of type [turtle_teleop/turtle_teleop_joy]: Cannot locate installation of package turtle_teleop: [rospack] couldn't find package [turtle_teleop]. ROS_ROOT[/opt/ros/electric/ros] ROS_PACKAGE_PATH[/home/turtlebot/tutorials/workspace:/opt/ros/electric/stacks:/opt/ros/diamondback/stacks]

This is using ROS Electric on Ubuntu 10.04 lucid. Any suggestions would be helpful. I just want to control the bot with the Ps3 joystick. Thanks.

  • Make sure you build your new package using rosmake, which will build the dependencies, including ps3joy, which will fix the first error
  • Make sure you have the turtle_teleop package installed and on your ROS Path, which will likely fix the second error.

Thank you. I noticed the default launch file works fine. I didn't notice that in the tutorial. I can now control the turtlebot with the ps3 joystick: roslaunch turtlebot_teleop ps3_teleop.launch
