Robots sharing information

[dave1027]

So during competition the robots and driverstations for each team are segregated by individual vlans corresponding to the team number. Is it possible for cross VLAN communication to occur? I an not a network engineer but i work with equipment on several VLANs and as long as there is no firewall between them, i can access information on the other VLANs as long as i know the IP i am looking for.

Specifically: If i have an IMU with its own controller and network interface at say IP 10.10.27.8, connected to my wireless bridge, could a member of team 256 (whos IP is something like 10.02.56.1) go to that IP and determine my location on the field? If so, all six robots could know the position of the other robots on the field.

Or could i go to team 256's onboard IP camera and pull images?

If there is a firewall between the VLANs, what do you think is the possibility of the Field Technical Authorities opening specific IP tunnels to allow this? As long as the IPs do not conflict with the communication path between the roboRIO, Driverstation, and field i would not think it is a problem.
