We are missing two of the pnematics cylinders, the lenses, etc. do 
you have any idea when we can expect the missing parts to arrive?  We 
want to order some new cylinders, but we are not sure which cylinder 
will be in the kit.

plywood decks to push or pull the goal up against your robot as long 
as you do not intentionally violate GM20.  FIRSTsnow

one back up at the 10 second mark and just re-pin the robot again or 
could they pin them for 9 seconds and then back away a bit and go 
back to pin them.
A) Rule DQ8 is quite clear.  You may create any defense system that 
does not violate other rules.  The pinning and backing-off scenarios 
you suggest are perfectly legal.  FIRSTsnow

Subject: 4 Atwood motors to clarify once and for all..!!!!!

I see questions in the posting that ask if you can use four drive 
motors and your answer was yes. Since there are not four of any one 
kind of motor, this causes some confusion!!!!! Let me ask 
this....Can we use four Atwood motors to drive the robot? 

Thanks! I hope you answer clears this up. Our team is debating this 
daily!!!!!!!!!
