Abstract: A launcher device includes a hopper having an open end disposed beneath a stack of UAVs. A retainer retains the UAVs in the hopper and releases one of the UAVs at the hopper's open end. A movable carriage disposed beneath the retainer receives the released UAV. The carriage is operable to be moved along a first direction from beneath the retainer to a terminus and subsequently operable to be moved along a second direction from the terminus to beneath the retainer. When moved in the first direction when the released UAV is on the carriage, the carriage moves the released UAV in the first direction to the terminus. A ramp aligned with the carriage guides the carriage along the ramp as the carriage is moved along the first and second directions.
