How does a camera gimbal work? What ‘reference’ does it use to know what is still?
In: Physics
Gimbals have existed since ancient times, historically they worked by aligning the object you wanted to stabilise at the exact centre of the concentric rings such that gravity always held it upright no matter which way the item moved or was turned.
Nowadays they also use computerised motion sensors (an “inertial measurement unit”) for additional stability, which then activate motors which help keep the object still and upright.
It depends on the gimbal, but it’s usually an algorithm combined with active management of the gimbal.
Some gimbals can track by/with GPS. You can feed coordinates into the gimbal and it will track that specific grid.
