Re: pic: 1710's Recycle Rush Chassis
OP, if you have tested this drive (or will be) and find that it does what you want it to do with the casters, then more power to you! Casters ARE NOT inherently a bad thing. Be aware of what the casters can do while going over the scoring bump, especially if you're turning into the bump rather than going straight at it from any distance away (this would give the casters time to straighten and align with your direction of travel). There is good advice in this thread, but don't be scared to try things!!
I drove a robot (casters in the back) in 2001 and never had any alignment or drive issues caused by the casters. We did, however, have a second set of drop-down traction wheels to aid in going over the teeter-totter however, but those were engaged for maybe 10 seconds of any given match.
