From the if-you-are-going-to-hit-yourself-with-a-hammer dept...

...use a small hammer.

By this I mean, that I think this is a pretty bad idea for lots of reasons... ...but if you are going to do it, do it as close to the motor as you can.

I have actually seen something like this used on some small toy transmissions. They did not have a linear engagement, but an arc one.

Essentially, an idler gear was mounted on an arm that pivoted about the motor's output gear. This arm's movement would engage gear A or gear B depending on the rotational direction of the motor. It worked for the toy.

I would not like to trust my robot's ability to move on such an idea, but to each his/her own.
