That being said, there are several dual-band access points that permit simultaneous 2.4 GHz and 5 GHz access. Is there a way to partition the robots such at we try to split up the use of the frequencies? Or at a minimum, use multiple access points on 6 different channels going into a switch such that the odds of having 6 robots on the field that all had the same channels would be minimized? Just trying to reduce congestion in the frequency bands so we're not stepping on ourselves during a match.

HTH,

I'm fairly certain we already used six separate access points. I'd imagine they're on different channels as well. The 5GHz range provides 19 non-interfering channels in the United States.

The camera could come off the 5v feed if it needed to, eliminating the PD board completely, some money savings for off-season projects. It could be designed for 2 analog modules, 1 digital module, and 1 solenoid module. the 32 DIO channels could have a fixed number of PWM's, DIO's, relays, SPI, and I2C. If you needed more than that, you could use modules like you have now in the remaining slots.

If FIRST could pull this off, my entire team will videotape ourselves giving a round of applause and send it to the engineers responsible.
