Biggest Con would be transporting it - ours probably can't come to St. Louis with us
. But I really like having a motorized cart for the 'bot. We started with one this year via a modified electric wheelchair base and it worked great. It makes it convenient and easy to transport the robot as well as any accessories, parts, batteries, etc. that you need to and from the field, but mostly it just adds to that all-important cool factor
.
But I will say I didn't see any other at Salt Lake this year, and I never remember any at Portland, Seattle, or Sacramento either. A motorized cart is definitely not a necessity, more of a luxury and convenience, but I like 'em. It would have sure made that walk from the pits to the field in Atlanta soooo much nicer!
