I have been following the video tutorial found at the following link: PR2 sim quick start with ROS Noetic - YouTube
I have been trying to get the PR2 to move with the following commands and I do not see any movement even when I echo it there is no message.
- roslaunch pr2_tc_gazebo world.launch
- roslaunch pr2_tc_description robot_spawn.launch x:=2.0 y:=2.0 z:=0.08
- roslaunch pr2_tc_teleop pr2_teleop_bridge.launch
- rostopic pub /pr2/cmd_vel geometry_msgs/Twist “linear:
It still does not work and just says “publishing and latching message. Press ctrl-C to terminate”
Then I did another terminal:
user:~$ rostopic echo /pr2/cmd_vel
linear: x: 200.0
Can you please help me understand why it is not been published?
Many thanks for your help!
