Re: Intermittent connection on field only
I actually had an oscilloscope at the MAR Mount Olive District event and someone took the time to check the power on a teams robot that was experiencing these symptoms. This was a 25Mhz analog scope and there were no issues.
Immediately I suggested it could be the camera feed, but it seemed like the other teams who were helping them were using it with better success. I also suggested it could be the CAN bus or somehow related to an interaction with the CAN bridge in the Jaguar....not to toss any blame on the Jaguars...I was merely speculating.
They were using LabView. We don't use LabView and I am not clear on how LabView handles exotic exception situations during communications.
When they turned off their video (which was a serious handicap for them) they could reliably control their robot on the field. As soon as they started using it again they had problems again.
I would like to point out, that I was told our field was apparently configured with 802.11G and everything was sitting on channel 6. I was told that's how it was setup and we all had to deal with it (even Team 11 and we were the host). That would mean that the most you can hope for is 54Mbps. However, with distance, interference, TCP/IP loading issues (it's a reliable protocol and if you don't understand the implications do some research or this will get too complicated to follow) you don't really have 54Mbps.
If what I was told was correct, this is going to be a problem if your robot is bandwidth hungry.
