I think I should include in Bluerov or VM some form of link both in the execution of Roscore
Something about
export ROS_MASTER_URI=_______________
but not which of the two and would have to put , I would also like it to work : ssh ubuntu"bluerov instead ssh ubuntu@10.0.0.20 because I think there must come the problem of communication between VM and bluerov.
Thank you very much to all the world
