I'm looking at the tutorial, and it looks like you need to remap the "cmd_vel" topic to "base_controller/command".
http://www.ros.org/wiki/simulator_stage/Tutorials/SimulatingOneRobot#Drive_the_robot_around
You can try running "roswtf" or "rostopic info base_controller/command" to see the status of the command topic. If the topic names don't match, the base controller will not receive commands from your keyboard.

Hello.
I have OS Debian Lenny
I have the same problems with diving robot in "Erratic simulation" and also in "Simulating One Robot in StageReading from keyboard" -
i can't drive robot with keyboard. I focus in the window where I ran teleop_base_keyboard, but robot doesn't answer the keyboard commands.
Maybe i forgot something to do.)
When i ran package teleop_base I see:
---------------------------
q/z : increase/decrease max angular and linear speeds by 10%
w/x : increase/decrease max linear speed by 10%
e/c : increase/decrease max angular speed by 10%
---------------------------
Moving around:
u i o
j k l
m , .
anything else : stop
---------------------------
And that's all. Robot doesn't move when i push the buttons.)
Thank you.
