# Can't get turtlebot_teleop to work with Logitech Logitech Cordless RumblePad 2 [closed]

Hello Turtlebot fans,

I am using the latest Debian Turtlebot packages under Diamondback on Ubuntu 10.04, and I'm trying to use the Turtlebot joystick_teleop_joy node to operate a non-Turtlebot robot that responds to Twist commands on the /cmd_vel topic. But before I get to that point, I am just trying to see the Twist values on the /turtlebot_node/cmd_vel topic (which is the default topic for the stock Turtlebot joystick_teleop.launch file.)

When I toggle the left joystick on the gamepad, the values on the /joy topic update appropriately (axes 0 and 1), but I get nothing nothing but 0's on the /turtlebot_node/cmd_vel. Does the rest of the Turtlebot stack have to be running for this to work? The steps I am following are:

$roslaunch turtlebot_teleop joystick_teleop.launch$ rostopic echo /joy (numbers update appropriately when left joystick moved)
\$ rostopic echo /turtlebot_node/cmd_vel (only 0's appear when moving left joystick)


Any thoughts?
