Finding Distance From Driver Station

Right now I'm playing with an idea for finding position based on the time it takes for a wlan message to take a round trip.

My goal is to do it in such a way that it would be legal, most specifically with R58.

The goal is to ping both the OPERATOR CONSOLE and the Field Management System. By knowing the position of both of those, and the distance from your robot to each you should be able to estimate your position.

I was wondering if anyone has any idea how to ping the OC or the FMS.

I am hoping that if this proves to be successful, that beacons (access points) could be put on the field, such that it could be more accurate. Similar to 2004 but using the wlan technology.


Quote:
<R58> One KOP wireless bridge (either model WGA600N or WET610N) is the only permitted mechanism for communicating to and from the ROBOT during the MATCH. The signal output from the wireless bridge must be directly connected to Port 1 of the cRIO-FRC with an Ethernet cable. All signals must originate from the OPERATOR CONSOLE and/or the Field Management System, and be transmitted to the ROBOT via the official ARENA hardware. No other form of wireless communications shall be used to communicate to, from or within the ROBOT (e.g. radio modems from previous FIRST competitions and Bluetooth devices are not permitted on the ROBOT during competition).
