distinguish arrived waypoint through mavros #542

Closed linzha0 closed 8 years ago

Hi, I am just wondering if I get the informations that indicated the waypoints had been arrived from the rostopic "/mavros/mission/waypoints". For example: 4 waypoints in the list, I can find the first two mission items have been arrived. "is_current" is described what I am talking about?

What do you mean on "arrived"? List is updated only after full transfer completion, except current flag (which anyway changes after recv).

is_current indicate that FCU execute this item.

I am using APM stack. The "arrived" means the waypoints have been went through or passed by UAV. is_current indicate the waypoint UAV flying to? Thx.

vooon commented 8 years ago

Yes, and at least APM do that (tested by me).

Hi @vooon , I found seq is the one I need to figure out what is passed waypoint. So I change the mavros_msgs/Waypoint to add seq and also the waypoint.cpp. but I got issue:

The dependencies of the message/service 'mavros_msgs/Waypoint' have changed. Please rerun cmake.

How I build mavros after change it. Thx

Why do you need it?! Siple array index is not enough?
