In Unit 1 Example 1.7 I consistently get the error:
ERROR: cannot launch node of type [turtlebot_teleop/turtlebot_teleop_key]: Cannot locate node of type [turtlebot_teleop_key] in package [turtlebot_teleop]. Make sure file exists in package path and permission is set to executable (chmod +x)
when doing the roslaunch step. As far as I can tell I followed the instructions to a t and didn’t do anything that would cause this sort of permission issues.
Any guesses as to how to fix this issue?
