Quadrature encoders. We have an idler wheel mounted right next to each driven wheel as part of our crab module, meaning we have 8 encoders. Those who are doing traction control will tell you that having as high of resolution on the speeds of these wheels as possible is a good thing, meaning we wanted 4x sampling. The new control system isn't capable of 8 4x encoders, and even if it was there were
bugs in the encoder implementation that we didn't know if they'd be fixed in time or not (I'm not sure if the issue mentioned by Joe Ross has been fixed even now). Additionally, this meant we only needed 4 wires to each module (power, ground, clock, and data) which we run down through the rotating shaft of our crab modules.
I'll try to grab a picture of one of the modules tonight.
