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.
