11-17: TAPS ARRIVED! yay

The wheelchairs are in! The wheelchair that is in the center of lab is there to be tested with, beat up on, drilled holes in, and to be used for all development in general. The Second wheelchair is in a box in the back corner of our space and will be used for the presentation. After everything is finished, then we wil just transfer the wheels to the presentation model.


 * Product Contract** - updated 11-03

Points to make for the assembly review
 * what is our ideal gearing: as broad a range as possible looked at how easy it is to shift gears
 * why don’t you have a high gear? - decided to focus on low gear markets
 * 600 lb person – what if someone engages the brake when going back
 * What will happen to braking when using the hand rim?
 * Don’t be defensive
 * “we will get feedback on this”
 * What if it rains?
 * It looks like a bicycle wheel – Ideally we want three spokes?

Possible Presentation Questions (From Erik) >
 * Why those gear ratios?
 * Why didn't you design your own hubs?
 * How did you choose the one-way hub loads?
 * How much rotational slop is there and how can you minimize it?
 * How do you turn hubs bi-directional?
 * Discuss the dangerous of engaging the one-way clutch at high reverse speeds.
 * Why no high gear?
 * How much width/weight/cost/time do we add?
 * Discuss the performance of a hub made for duel mounting, now cantelievered.
 * How are we different from Magic Wheels?
