Re: Thank You IFI
 
I'm happy to say "thank you" to all of the sponsors and equipment designers that have made FRC what it is.

I do, however, have to say that wifi appears to be a challenging environment for robot control systems, regardless of manufacturer or platform... particularly at major events where there are many sources of interference.

I appreciate the hard work that all the control systems designers are putting in to alleviating these issues.

Here are a few potential platforms,

1. cRio: https://decibel.ni.com/content/docs/DOC-19103
2. VEXpro Arm9 : http://www.vexrobotics.com/217-2180.html
3. VEX Cortex : http://www.vexrobotics.com/276-2194.html
4. Open Source : Embedded Microcontroller with Linux Laptop

Does anyone know of other potential candidates for a robot control system ?
Beagle Board?

Maybe FIRST just needs to design a faraday cage that surrounds the field and scoring table.:rolleyes:

Welll.... now that you mention it... we were recently at a local school helping them out with some VEXNET problems they had been having. Their robot worked great everywhere but inside their school. We figured it probably had something to do with the school's wifi network running some kind of filter, and that all we needed to do was put a faraday cage around the field and we'd be fine.

Then one of the students asked if there was a bit of sheet metal, went to the metal shop and folded up a little box, stood on a chair and placed it over the wifi router. All of a sudden the robots worked!

Obvious in retrospect..... but brilliant at the time.
