2016-04-07 12:57:11 -0600 asked a question How ROS Packages work with each other?

Update2:

As the source code is configured in a catkin workspace, does every package needs a catkin work space or I can put all what I need and what I am developing in one workspace?

Thanks for the answer from @jarvisschultz


Update:

If I want to make modification to some packages, should it be installed by source or sudo install? Any difference?

Thanks for the answer from @jarvisschultz


How ros packages work with each other?

There are packages built from source or built from binary packages, but how do they work?

Any explanations or examples are welcomed

Hi, thank you very much for your reply. Would you like to share the global planner you use? And which ROS release and dependency packages were used? Thanks in advance :3

2016-04-05 00:14:43 -0600 asked a question Beginners: Quadrotor Path Planning Simulation and examples of making use of packages from source?

Hello,

I plan to test some implementations of quadrotor path planning which have already been done in matlab.

The first stage I want to do is to let a Hector_Quadrotor model move from Point A to Point B in a clear map.

As far as I know, I need

a simulator (Gazebo, good choice?)

a uav model (I chose Hector_Quadrotor, how to utilize it?),

something for *motion planning ad autonomous move (This is what I have no idea yet!).*

Any suggestions on these will be highly appreciated!

Examples of making use of packages built from source will also be extremely useful.

Thank you for any help in advance!

Hi, may I know what modifications you have made on that to make this project run? Thank you in advance.
