Tears of the Kingdom
"A Zonai device built to move efficiently over flat surfaces. Apply force to get it moving, so long as it has a power source."
Carts are wheeled, unpowered Zonai Devices. They can be pushed, moved by powered Zonai Devices such as a Fan or Rocket, or roll downhill unaided. In Jirutagumac Shrine, a cart and fan are used to roll a Wing forward, enabling it to take off without a rail. Similar devices include Homing Carts, Sleds and Hover Stones.
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.
