why cant we use rosrun turtlesim turtle_teleop_key?
what i did was :
roslaunch beginner_tutorials turtlemimic.launch
Then two turtle simulators opened
and then i did:
$ rostopic pub /turtlesim1/turtle1/cmd_vel geometry_msgs/Twist -r 1 -- '[2.0, 0.0, 0.0]' '[0.0, 0.0, -1.8]'
the both turtles started rotation
I want them to move using ARROW keys so i killed the above process and then i did:
rosrun turtlesim turtle_teleop_key
but it doesnt work! so how should i control them using arrow keys?
If the only effort you can put into describing the problem is "it doesnt work", we can't help you. Go read http://www.catb.org/~esr/faqs/smart-q... and then edit your question to add terminal output and a description of how it doesn't work.
