ROSInterface question: ROS Node at another machine

[Klaus]

Hello all,

According to this:
http://www.coppeliarobotics.com/helpFil ... Interf.htm

When we want to use ROS with Vrep, what happens is that once we start Vrep with ROSInterface support, it finds a roscore running in the network and creates a ROS Node that serves as communication point between VREP and the ROS network. Something like this:

Scenario 1

• Machine 1
  • VREP
  • VREP's ros node
  • roscore
  • other ros nodes
  • ros master

Due to how computationally demanding VREP and other ros nodes (e.g. image processing, path planning) we are running VREP in a separate machine. Something like this:

Scenario 2

• Machine 1
  • VREP
  • VREP's ros node

• Machine 2
  • roscore
  • ros master
  • other ros nodes

However, we would like machine 1 not to require a ros installation to work. And focus only on running VREP. So the ideal case would be something like scenario 3:

Scenario 3

• Machine 1
  • VREP

• Machine 2
  • VREP's ros node
  • roscore
  • ros master
  • other ros nodes

In this case, everything related to ROS would be running in a separate machine.

Question; is this possible?


Regards,


Klaus

The RosInterface plugin requires ROS.

Moreover, it is not possible to run V-REP's (RosInterface's) ROS node without V-REP.
