Turltlebot does not move #555

Open pulver22 opened 7 years ago

pulver22 commented 7 years ago

We are using Ubuntu 16.04 with ROS Kinetic and Gazebo 7. We downloaded turlebot_gazebo package, compile it without issues and spawing world and robot. We publish a message on on /cmd_vel but the turtlebot does not move from its position despite the messages are published on /turle1/cmd_vel.

Do you have any idea of what is going on?

Cheers!

Sorry it has taken so long for someone to look at this issue. I'll need some more details to help you. Are you simply running roslaunch turtlebot_gazebo turtlebot_world.launch or are you running some custom code? If so it's possible you are just using the wrong topic. From this tutorial try:


rostopic pub /mobile_base/commands/velocity geometry_msgs/Twist "linear:
  x: 0.0
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 1.0" -r10```
