This is why we didn't have DIY Drones in the 1970s. (Mechanical gyro teardown)

Just look at the complexity (and size/weight) of this mechanical gyro! Now that functionality (times nine--three gyros, three accelerometers, three magnetometers) is performed by a $15 chip smaller than your fingernail.

Wow. That is amazing.

Technology has come such a long way.

Today's gyro are almost identical, I didn't notice the difference ;)

We had drones in the 70's: they were classified as pigeons and balloons... These aircraft gyros needed the weight for sheer momentum/precision at low rpm. Cool fine.

I love it, the old F-16 use to have a mechanical one too...imagine that!

It got us to the moon.

Is there anything where MEMs underperform comparing to mechanical gyro ?

Is there any reason to still use mech gyro for some specific application ?

Yes, stabilizing a camera.

Do you know why ?

Comment by Don LeRoi on July 18, 2012 at 4:24am

The spinning mass of a mechanical gyro resists movement of the object to which it is attached.  Its response is instantaneous.  A MEMs gyro simply provides the information to a stabilization system that then has to react to that information.

Don, it's not *that* type of gyro.
