A mechanical gyroscope uses a spinning rotor in the centre to maintain a reference point in 3D space: if the frame is tilted, the angular momentum of the rotor resists movement, and the gimbals allow ...
A brief overview of polhode motion in the gyro rotors The gyroscope’s polhode motion is akin to the common “wobble” seen on a poorly thrown (American) football, though it shows up in a much different ...
