I think you fail to understand what I'm saying, and the main principle behind my comment.
Any torque applied through THIS design, will cause the gears to try to disengage from each other. The only thing preventing this is the force of the pneumatic, holding the shafts together.
In a Dog-style, Pin-Style, Mesh-Style... Shifter, the kind of shifters we see every day in this competition: The shafts are held rigidly. Therefore the applied torque CANNOT seperate the gears from meshing (unless it deflects the shaft, which is a discussion for another time).
See the major differences?
See why Matt's design would have MAJOR torque limitations that wouldn't apply to a "normal" shifter?
I can guaruntee you haven't seen any design like this one in the FRC, so it is unfair of you to draw parallels between this box and another and make broad statements concerning it's capabilities.
I love 469, they are a great team, their last 2 bots have been works of art, and their 2002 bot kicked my butt pretty hard. Great designs, in every part of their bots, including the shifter.
But... that doesn't really apply here, now does it?
Unless you understand all the principles involved, and the design itself... which you've shown some confusion about... perhaps you should limit the broad statements you make about it?
