Help with Gearboxes

[Suneet]

On my team, two groups of people came up with hypothetical gearbox designs. I head one of the groups, and I feel it has a better design than the other (shift gears on the fly). This is my third year doing robotics, so I did a full hypothetical model in Inventor (sans a motor mount, and other smaller details). We'll have to see the game and kit to procede further. To use four motors, I planned to make a separate box for each wheel, two motors per side. (inspired by team 60 ) Bit it depends on the game...

I'm no expert, but instead of putting the output of two motors on one shaft, it might be eaiser to make 4 gearboxes and have two motors per side. That's what I hope to do. But if you want just two boxes, I think it's better to use chain instead of gears, cause they're a bit more... forgiving than gears.

Also, there's tons of boxes in the whitepapers. Take a look:
