Can Groovy machine connect to Indigo master?
I try to communicate two different machines using ROS, but they have different ROS version. Is there any compatibility issue? I have a robot installed with Ubuntu 12.04 and ROS Groovy, and a laptop with Ubuntu 14.04 and ROS Indigo. The two machines are connected by an Ethernet cable. I could ping each other from both machines and the ROS_MASTER_URI variables are exported to be the same. However, my robot cannot find the master node on my laptop.
I guess it is due to compatibility issue between the two ROS versions. Is there any solution besides reinstall the whole system? Thanks a lot!
