  • Patent number: 11027840
    Abstract: An aerial system includes a body, a propeller coupled to the body, and a motor coupled to the propeller. The motor is configured to rotate the propeller in a first direction, wherein an other portion of the aerial system rotates in an opposing second direction. The other portion of the aerial system that rotation in the opposing second direction may be the body or a second propeller. The aerial system also includes a processing system configured to control the motor to cause the aerial system to hover in a substantially fixed pose, and a camera configured to obtain images of an environment proximate the aerial system while the aerial system is hovering.
