Hi, i am new in ROS, so i am sorry for possible stupid questions. I try my robot (platform on caterpillars) to explore the unknown location offline. I use hector-slam (version of ROS - Indigo). I think, i need in hector_exploration-planner (to get trajectory for exploration) and hector_exploration_controller (to send velocity to car). I launch hector exploration node and controller. It generate exploration path with some poses, find frontiers. And, if i understand correctly, i should subsribe exploration_controller to topic /exploration_path by exploration_node and send cmd_vel to car? How can i do the second?

Thank for any help.

I did a node, subscribed to /cmd_vel. But now car move only backward. In cmd_vel topic only the same messages: linear x:0.1 and angular z:1.4
