Tears of the Kingdom
"A perfectly balanced Zonai device that stands upright when activated. It was used to secure footholds in unstable places, such as sky islands."
Stabilizer is a type of Zonai Device. When activated, they immediately jump into a vertical state and stay there. They can be used to force vehicles with fewer than three wheels to stay upright, or for makeshift catapults by rapidly forcing a long object it is attached to into a vertical position. Makasura Shrine ("An Upright Device") serves as a tutorial in their use. Outside of shrines, if Link is the one to activate one, it drains his Energy Cell while active.
As with all Zonai Devices, they can be found in Zonai Capsules from Device Dispensers or Treasure Chests; or lying around in the overworld. If removed from a capsule, they cannot be returned to it, although they can be fused to weapons or shields.
