Hey there,

Here's some basic questions to start you off:

-Is this the lightest way you can build an elevator?
-Is this the least resource intensive way for your team to build an elevator?
-Why is a rack and pinion setup better then a string and drum?
-Will the channel of the middle stage deform being pushed on from the inside and outside by the inner stage and the rack and pinion?
-Is putting the motors up high on the elevator really the right place?
-Will your roller brackets deform over time or when the inner/middle stage takes an impact?
-Is using the motor as the front top middle stage container really a very good idea? If so could the motor be moved higher to improve your lever arm in the front containing the middle stage?
-How is this going to be attached to the actual robot?
-Is the single round crosspiece on the middle stage enough to keep it torsionally stiff?
-Do you have a plan to closely control the motor and pinion relative to the rack? (spacing wise?)

Looks pretty good overall.
