Chief Delphi - Robots sharing information

Then integrate light based communications into all 3 robots and make them electronically cooperative. If it wasn't for some of the rules maybe make them join into a bigger robot after the match started.

The trick is not really finding a way to communicate in a way FIRST might approve and may not even realize you have been doing. The trick is getting everyone involved on the same page to leverage it. Any team with a camera and a light source right now could strobe that light source and read that with the camera off the retro-reflective tape allowing the robots to communicate. FIRST already approves the cameras and the light sources. So really what can they do about this in the absence of a new rule?

You could actually code this at the competition and probably wire it up if you can get all the people involved to cooperate.

Building on, you could use a wide-range, moderate-power infrared LED/sensor with a coprocessor. You could possibly create some sort of PPtP tunnel over this if treated like a serial port!

Two robots:

PHP Code:


		
			
} >=====[PPTP]======> ]

[ <=====[PPTP]======< {



Robot 1:        Robot 2:

Tx } >=======[PPTP]======> ] Rx

Rx [ <=======[PPTP]======< ] Tx

Basically, you can treat this like an opto-isolator. This can potentially give a very high speed with very low latency. However, I would use some modulation, say 100kHz to filter out the noise! Make sure that is much higher than the baud you want to use!
