Besides there's no rule you have to transmit IP at all, or even this sort of traffic at any level in that particular range. Course eventually you'll get the FCC's attention if you go too crazy, but that sort of stuff shouldn't need to happen for what you ask.
Given the (very) real-time nature of what we're dealing with, UDP is probably best. I mean really, if the robot loses a packet, by the time it figures it out, the data is ancient history. I'd retain TCP for important things like software downloads and such, where losing data is actually quite bad.

I suppose, Wi-Fi itself isn't really the problem, but more the actual radio hardware setup we have now, so that could probably be improved on without being replaced entirely.
