R/C helicopters
 

i was wondering if you could use gyro's from model helicopters. I've done research on them before, but i'm not sure if you can use them for robots.

They have to fit within the cost rules. But typically helicopter drive the PWM directly to the motor and that is not legal.

Run them through the flow chart for part legality.

Unless you can get them from one of the approved suppliers of electrical parts, i doubt if you can use them, but then again i haven't slept in 2 days, so i could be wrong.

You all need to check the Q&A, the answer was given that the type specified and shipped in the KOP are the servoes you need to use.

You're probably referring to R38:

Fishdude404 was asking about gyros, not servos.

Assuming it falls under the cost limit, I don't see anything in the rules (or the flowchart) that would, um, rule out a helicopter gyro. Passive sensors of pretty much any sort seem to be permitted.

About gyros driving PWm applications:

Typically speaking, you are right. In a model, a gyro hooks between the controller and the servo that requires the mixing. In the robot, however, you can use the PWM that would normally drive the servo to input into the robot controller (you may need to feed a 50% duty cycle into the gyro to simulate a neutral stick. Because gyros disengage when the stick moves from center, you may have to make it seem like a center stick all the time.)
