With my experiences with baseball fields, absolutely. While these robots were designed to withstand Sandstorm, it’s not quite the same.
I’m not sure what your robot looks like, but the first thing I could see getting really dirty/dusty would be drive train, for obvious reasons. If you don’t mind the robot getting generally dusty everywhere, you’re fine. Just be aware there could be quite a bit up into the drive train, getting into your chain/belts. Also Just make sure your electrical board is completely covered. This includes from the bottom, as the wheels will most likely kick up the dirt up into the bot. Try to cover the main electrical board specifically. PDP, VRM, PCM, RoboRIO, all the main “brain” stuff. You can’t put a vacuum up to a roborio, so keeping as much out of there as possible is ideal. as for motor and other general connections, if you can keep them isolated, great. If not, I don’t see it as being a super big issue.
