I have problem with teleop by keyboard. After bring up kobuki roslaunch turtlebot_bringup minimal.launch, I cannot teleop by keyboard using roslaunch turtlebot_teleop keyboard_teleop.launch. However roslaunch kobuki_keyop safe_keyop.launch works well. Could you explain for me? it seems ros packet for turtlebot 1 is not running for kuboki ( I also tested with turtlebot_follower and gmapping_demo and it didn't worked on kobuki). Thanks

Hi !

I tested all the packages from the tutorial on a Turtlebot 2 and they were all working (except the Panorama one because I missed a library and didn't want to install it).

Did you start the teleoperation from turtlebot_teleop through ssh ? This might be the source of your troubles if you haven't.

But you can't use packets from the Turtlebot 1 on kobuki since many topics (and some other things I guess too) have been changed. So you need to install the ones which were released for the Turtlebot 2.

My guess is that you just need a topic remapping. The kobuki packages configure the cmd_vel_mux, so teleop inputs are usually on /cmd_vel_mux/input/teleop. Older packages might still publish to /cmd_vel directly.

Since kobuki uses nodelet for velocity command multiplexer. For P3AT robot, if I want to use yocs_cmd_vel_mux (https://github.com/yujinrobot/yujin_ocs); then remapping is enough? What modification we have to do to achieve similar behavior of TurtleBot 2? I am using fuerte on ubuntu 10.04.
