Unless you are on a vibrating platform (like durring an earthquake) I don't think the electronics will suffer much. Well... maybe the CMU Cam, but that is extreamly delicate. I would be more worried about the condition of the wheels afterwords. Pavement tears up plastic wheels (unless they are really hard plastic, which I doubt). You might consider getting replacement wheels for afterwords or getting cheep wheels for the parade. Or whatever you think you should do about damaging wheels. If riding accross pavement would hurt the electronics, I don't think they would survive much in compatitions.
