ROS interface automatically adds prefix to a service topic

[Filipe Rocha]

Hello everyone.

I am using vrep_ros_interface to communicate my simulation with ROS.

When advertising a service, I use the following LUA command:

Code: Select all

serv_handler = simROS.advertiseService('/srv_topic', '/std_msgs/foo', 'my_service_callback_function')

However, the interface generates a service topic with the following name:

Code: Select all

/vrep_ros_interface/srv_topic

It automatically adds the /vrep_ros_interface prefix. This is a problem for my application, as we are replicating a real robot interaction and the real service does not have this prefix.

Is there a way to remove that prefix?

Thank you in advance, and congratulations for the awesome simulator!

RosInterface does not add any prefix.

This is the Lua callback for simROS.advertiseService, and this is the included srvsrv.cpp which calls NodeHandle::advertiseService, as you can see it passes in->serviceName (the string "/srv_topic" in your case) directly to ROS.

Have you tried using "srv_topic" instead of "/srv_topic"?

Can you post the output of "rosservice list"?
