Turtlebot2 Simulation

[rmerriam]

Trying to run this in simulation. Gazebo runs and shows the Turtlebot and other objects. Running the

roslaunch turtlebot_teleop keyboard_teleop.launch

doesn't cause any movement. I don't see any message when looking at

/cmd_vel_mux/input/teleop

Any suggestions?

Also the depthimage_to_laserscan nodelet doesn't load but I'm not concerned about it at the moment.

Hi! Can you send your stdout showed in the terminal?

Hi. I think your problem may be caused by communication problem with rosmaster.

Try use roscore to start a rosmaster in advance, and then bring up other nodes.

Otherwise, if you use turtlebot_teleop to start a rosmaster by default, and after that you restart the turtlebot_teleop, all communications created before will be broken. So rostopic echo /cmd_vel_mux/input/teleop won't prompt anything new!

Does anyone know how to solve this problem?

I figured out this problem.follow the following tutorial ,then you can use keyboard to control turtlebot.
