Revision history [back]

There seems to be a bug in the script responsible to set the speed of the robot because you do have the topic /mobile_base/commands/velocitypublishing data (this is the topic that moves the robot) but this data is always only 0 eventhough you press some keys and the script prints different speeds. So you can either investigate the script turtlebot_teleop_key or instead you can use another launch file that is working fine that use the mobile_base of the turtlebot directly (i.e. kobuki).

Try:

roslaunch kobuki_keyop keyop.launch
