just wondering

also the link to the inventor files doesn't seem to be up anymore
There have been several teams who have used servos to shift, and AndyMark does sell a servo shifting version of their shifter. However, while servo shifters often accomplish the task, many do not perform as well (ie shift as quickly or as reliably) although they are certainly more than functional.
The pneumatics vs. motor debate is an old one, and best saved for another thread, but if you did happen to have pneumatics on your robot, I would suggest using them to shift, but if you didn't it probably wouldn't be worth installing pneumatics just for shifting capabilities.
