I agree with the second post: Have the collision trigger both the touch sensor
and the firing mechanism. This leaves both motors free to drive. Using the
differential will work fine (although I'm not sure if it comes in the RDS or
not), however being able to turn in only one direction gets annoying after a
while. (The Photobot II uses this mechanism - see
