roboRio limited to 8 Analog Inputs

Suppose you have a lift? It would be nice to know where it is, yes?

Maybe you want to know where a tote is as try to align to it for a pick up or a drop off? Switches are nice, but analog values seem better don't they?

How about a chassis something akin to this one? Sure would be nice to know which way your wheels are pointing, yes?

Maybe you have something for picking up cans? Sensors to help position things or to discover the can location add up.

How about a gyro or two together with a 3 axis accelerometer?

Getting over 8 analog inputs seems pretty easy.

As to encoders, they are great but they have the problem of not knowing where they are when you wake up. I'm not saying that FIRST did a lousy job preventing brown outs with the new control system but I am saying that I wouldn't bet my season on the robot never going dark momentarily during a match.

Callin' 'em as I see 'em.
