Abstract
Certain embodiments of the present application relate to an unmanned aerial vehicle including a control system, at least one rotor operable to generate lift under control of the control system, a spool mounted for rotation in a winding direction and an unwinding direction opposite the winding direction, a motor operable to rotate the spool in at least the winding direction under control of the control system, and a brake mechanism including a brake actuator operable to transition the brake mechanism between a locked state and an unlocked state under control of the control system. The brake mechanism in the locked state prevents rotation of the spool in at least the unwinding direction. The brake mechanism in the unlocked state does not prevent rotation of the spool in the unwinding direction.
