In fact, Apple founder Steve Jobs was the first one to popularize the usage or application of the gyroscope in consumer electronics; he did so by using them in the Apple iPhone. Since then, gyroscopes have come to be commonly used in smartphones. Moreover, a few features of Android phones - think PhotoSphere or Camera and VR feature - can not work without a gyroscope sensor in the phone.
It is the Gyro sensor in our smartphones that senses angular rotational velocity and acceleration. This is what makes it possible for us to play using motion senses in our phones, tablets.
When we move our phone, the photo or the video moves due to the presence of a tiny gyroscope in the phone. In toys : Gyroscopes are also used in toys, in fact there are toy gyroscopes which make for great educational tools as they help kids understand how gyroscopes work.
In bicycles : Electric powered flywheel gyroscopes inserted in bicycle wheels are said to be a good alternative to training wheels. In cruise ships : Cruise ships use gyroscopes for leveling motion-sensitive devices such as self-leveling pool tables.

This blog takes a look at all this and more… What is a Gyroscope? A Brief History of Gyroscopes Essentially, a gyroscope is a top combined with a pair of gimbals. How does a Gyroscope Work? Hemispherical Resonator Gyroscope HRG Also known as a wine-glass gyroscope or mushroom gyro, the HRG makes use of a thin solid-state hemispherical shell, anchored by a thick stem. Vibrating Structure Gyroscope Also known as a Coriolis Vibratory Gyroscope CVG , a vibrating structure gyroscope is a gyroscope that uses a vibrating structure to determine the rate of rotation.
Ring Laser Gyroscope A ring laser gyroscope uses the Sagnac effect to calculate rotation by measuring the shifting interference pattern of a beam split into two-halves, even as the two-halves move around the ring in opposite directions. Fibre Optic Gyroscope A fiber optic gyroscope uses the interference of light to detect mechanical rotation.

If you mount the gyroscope in a set of gimbals so that it can continue pointing in the same direction, it will. This is the basis of the gyro-compass. If you mount two gyroscopes with their axles at right angles to one another on a platform, and place the platform inside a set of gimbals, the platform will remain completely rigid as the gimbals rotate in any way they please.
This is this basis of inertial navigation systems INS. In an INS, sensors on the gimbals' axles detect when the platform rotates. The INS uses those signals to understand the vehicle's rotations relative to the platform. If you add to the platform a set of three sensitive accelerometers , you can tell exactly where the vehicle is heading and how its motion is changing in all three directions.
With this information, an airplane's autopilot can keep the plane on course, and a rocket's guidance system can insert the rocket into a desired orbit! Sign up for our Newsletter!

Click here to download the second full-motion video showing precession at work. In figure 1, the gyroscope is spinning on its axis.
In figure 2, a force is applied to try to rotate the spin axis. In figure 3, the gyroscope is reacting to the input force along an axis perpendicular to the input force. If the top is tilted then these two forces are not opposite each other, as in the picture, so generating a couple.
This couple is fixed, independent of how fast the top spins so with paragraph 3. A couple is just any pair of equal-and-nearly-opposite forces that act to twist something around. Gyroscopic effect: 7. A spinning rotor has an axis of spin.
A couple acting about this axis can only ever change the spinning speed 9. To change the direction of the axis of spin the only remaining possibility is to apply a couple at right angles to the spinning axis. The axis of spin will deviate so as to direct its spin in the direction of the applied couple. This is called Gyroscopic Precession".
More precisely, "the angular momentum changes in the direction of the applied couple". Angular momentum is a measure of how fast the rotor is spinning.
With reference to the diagram, the spin axis angular momentum is the black arrow and it responds to the applied couple green arrow by changing in that direction red arrow to give a new spin axis blue , and this change in direction is called "precession" orange. These "arrows" are called "vectors", but never mind that. To figure out the arrow relates to the direction of spin just point along the arrow and then wiggle your finger clockwise.
There's an important result from all of this - you get slower precession if the spin is fast or if the couple is small.
