run/stop a node after other node stops

Hello everybody,

I am running multiple nodes, one of them (an exploration node) stops working when it finishes its task.

I am hopping to run and stop another different nodes when this happens.

can anyone please help me with telling me which tools I might use for this?

I am using ROS kinetic and gazebo 7.x

Thanks!

For the case, you want to end other nodes with the exploration one, check here

I guess there is no built-in way to handle this out of the box. (Besides what @kosmastsk suggested, though this seems kind of harsh :-) ).

Two way come to my mind:

implement some kind of service in your exploration node which triggers the shutdown of the respective other nodes. With a service, you'd be able to check when the shutdown has occured.
use a bond. This is specifically implemented to provide the functionality you'd like to have.
