Dear all,

Right now I am working in a project that will involve the creation of several nodes following the VREP-ROS approach.
From your perspective, which is better to use: ROS Services or ROS Topics as a means to communicate with VREP.
I also intend to use the rospy library intensively.

Kind regards and many thanks for your help.

Antonio.

Hello Antonio,

you should use both of them, depending on what you want to do!

But very briefly:

• With services, you will get a concrete reply for your query, e.g. what is the handle of object 'joint42'?.
• With topics, you will stream data that is often used and often changes, e.g. send me continuously the position of joint with handle x.

Cheers
