Shifting with servos

[Micah Chetrit]

Hello,
our team has never used a shifting gearbox on our robots before, and we are considering using an andymark 2774 to have a shifting system similar to how RI3D released their shooting mechanism. We don't plan on having pnumatics on our robot because the only place we would use them would be on the shifter, so we thought about using a servo to actuate it.
Can a servo handle it well? I doubt that the force required is as simple as the force required to move a lightweight dog gear since there are other forces acting on the gear, so I don't know how much resistance to expect. Are there any issues you foresee with using a servo to release a launching mechanism?
