Gyro

I am looking for something on a larger scale, needing to adjust/control 50-100 lbs.

Try the aircraft wreckers for the Inertial navigation system components. The Very Early ones worked directly, however they had a 1/2% error rate which isn't any good over distance, being 1 mile off course in 200 mile distance!

There are model Helicopter Gyros and Ring lazer gyro simulators which might be adapted to drive a heavy servo or two.

Finally the old Gunnery sight stabilisation Gyros used on warships were direct drive, but I think most of them have gone to god by now!

how much bedget do you hve?

The little ones we used in the Milan anti-tank missile were pretty impressive...

However, they had a very limited lifetime!!

Hi,

A: try to get a copy of Savet: The Gyroscope, Theory and Applications, Wiley 1964 or so. A lot of useful infos.

B: A gyro maintains its angular orientation with respect to an inertial frame. So if you want to stabilise something you have to get a gimballed suspension (2 axis minimum, up to 5 axis nested one inside the next if moved on a vehicle.)

The bearings of the gimbals have to be of utmost quality, balancing too, temperature stabilising ...

C.: You can get short time medium quality stabilisation with a passive gyro. Post your requirements!

RHABE

it principle of angle momentum conservation. high speed rotation object keeps its axes direction unchange.

I remember, ship use it for it stabilize.

Hi Gmm,

Google; Gyroscope. com They have an electronic gyroscope at a cheap price!

Spencer.

Commercially, the artificial horizon used in aircraft instrument panels contains a gyroscope that maintains a horizontal orientation. As others have said, you can buy toy gyroscopes and they are fun to play with.

Thanks for all the info, and I'll try to get some requirements posted soon.
