As for replacing a servo with a different type of motor, that is a bit of a challenge. Servos have internal feedback which allows you to tell it to go to a particular position. You may notice that if you have a servo powered and you try to turn it, it fights back to keep the position the same. The servo just has a small motor inside, a controller, and a sensor for feedback. If you want a globe or fisher price motor to act like a servo, then you need those other two components. You can use a sensor like the Gear Tooth Sensor included in the kit as your feedback. For the controller, you can use the FRC and write software! The motor controllers that have available, (victors, and of less usefulness, the spikes) only control the speed of the motors, not the position. This is because they don't know where they are, and therefore don't know where to go from there (where?). Hopefully the servos will work for you, but if not, it's possible to use other motors instead. It's just a lot more work. If you decide you do need a controller and motors, do some research/googling for PID control. It's a pretty straight forward method of control that gives good results. There's probably even code floating around out there if you look hard enough.
HELP!!
can we not avoid using the gear tooth sensor by setting our fischer motor, globe, etc. at a low enough speed? then when it finds the light to stop?? if this is possible, where in the code do i do this. i'm not the greatest programmer but i need to figure this one out!! if canybody can help that'd be great
