    Abstract: Disclosed is a drone rotor cage. The drone rotor cage may include a motor housing, a plurality of spars, and a plurality of ribs. The plurality of spars may extend from the motor housing. Each of the plurality of spars may have a spar height and a spar thickness. The spar height may be greater than the spar thickness. Each of the ribs may extend from a respective one of the plurality of spars. Each of the plurality of ribs may have a rib height and a rib thickness. The rib height may be greater than the rib thickness. The plurality of spars and the plurality of ribs may define a space sized to allow a rotor to spin freely when the rotor cage is attached to a drone.

    Abstract: An unmanned aerial vehicle comprises an image sensor, configured to detect electromagnetic radiation and to generate image sensor data representing the detected electromagnetic radiation; a filter, configured to pass image sensor data representing one or more first wavelengths of electromagnetic radiation and to block image sensor data representing one or more second wavelengths of electromagnetic radiation; and one or more processors configured to determine from the passed image sensor data an origin of the detected electromagnetic radiation; and control the unmanned aerial vehicle to travel toward the determined origin.

    Abstract: Multi-stage reduction of impact forces are disclosed. An example apparatus to reduce impact energy of an aircraft during landing includes a rotatable landing leg having a proximal end near an axis of rotation and a distal end opposite the proximal end, a first flexible portion of the proximal end, where the first flexible portion is to engage a first engaging portion at a first rotation angle of the rotatable landing leg, and a second flexible portion of the distal end, where the second flexible portion is to engage a second engaging portion at a second rotation angle of the rotatable landing leg.
