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wrong, it's just I found alot of the robot frameworks seem to have broken dependencies on Maverick, or tutorials are out of date and it affects uptake.
