Hi everyone, now I create a model in gazebo and wanna control it through arrow keys. To put it simple, I want to write a program that works as rosrun turtlesim turtle_teleop_key, but on my custom topic cambot/cmd_vel. How can I get the source code of turtle_teleop_key?

I would recommend to use teleop_twist_keyboard for this. No need to write anything yourself (it already publishes Twists to cmd_vel, so just remap), but if you really want to, see ros-teleop/teleop_twist_keyboard for the source.
