Implementation of two subscribers
Hello. I am a ROS beginner. I am doing SLAM of turtlebot 2 in the ubuntu 14.04, ros (indigo) personal computer environment.
I want to call the callback function every time a topic / cmd_vel is delivered, but I also want to use the message of the topic / scan in the callback function.
I also want to distribute the topic / navigation_velocity_smoother / raw_cmd_vel within the callback function. Oysters How do I write the code?
Thank you.my friend.
