understanding ros topic tutorial teleop_key problem

joe
hiya,

very new to ROS installed on Ubu 10.10, ros cturtle as per install instructions.

Fresh install of ROS, roswtf no issues

working through tutorials fine until I get to

understanding ros topic


     We'll also need something to drive the turtle around with. Please run in a new terminal:

               $ rosrun turtlesim turtle_teleop_key

get following error

[rosrun] Couldn't find executable named turtle_teleop_key below /opt/ros/cturtle/stacks/ros_tutorials/turtlesim



played around, searched  for a bit and found......

http://www.ros.org/wiki/turtle_teleop

(1) rosdep install turtle_teleop
(2) roscd turtle_teleop
(3) roslaunch launch/turtle_keyboard.launch

this seems to work.....with turtlesim

am I doing something obviously wrong, it's just I found alot of the robot frameworks seem to have broken dependencies on Maverick, or tutorials are out of date and it affects uptake.

Thanks

Dave

Hey Joe-

I recently moved turtle_teleop_key from the turtle_teleop package to turtlesim which is probably the problem you're seeing.. you found the correct solution, the debs were just out of date.
