The Tradonata is a mechanical ornithopter designed by Aidana Engen for discreet personal courier work. Modelled closely on the anatomy of the dragonfly, it employs four independently-moving wings, six articulated carrying arms, and a compound-style crystal optical array to navigate autonomously between pre-established pickup and drop-off points. Lightweight but deceptively capable, it can carry parcels of up to ten pounds across considerable distances using only solar power and a radio receiver for guidance.
History
Aidana Engen, spending much of their time coordinating the preparation and delivery of various war materials, began searching for a courier method that was both discreet and difficult to trace. Most of the parcels they needed to move were too heavy for any trained organic bird, which led them to consider an alternative: an automaton that borrowed the bird's role but exceeded its limitations.
Drawn to the flight principles of flying insects - the interplay of lift, drag, and independent wing propulsion - they settled on the dragonfly as their design basis, specifically the order Odonata. The insect's four independently-operating wings offered superior manoeuvrability over conventional fixed or paired-wing designs, while its famous near-total field of vision inspired the Tradonata's crystal-lens optical system, shaped after the ommatidia of compound eyes. The result is a machine that mimics its biological model closely enough to pass a casual glance, while carrying considerably more than any real dragonfly could dream of.
Construction
Construction begins with the hull and frame. Sheets of Aerin and iron rods are carefully shaped and bent to form the segmented lower thorax and abdomen, with precise tolerances required to keep all internal components stable and properly seated. Once the body is assembled, the six legs are constructed: each is built from smaller overlapping Aerin plates for flexibility, three-section rods with hinges, and rubber-lined wire tubes that act as artificial muscles - when tension is applied at the upper end, the arm curls and locks into a grip.
With the frame complete, attention turns to the power system. A teardrop-shaped Luminarite Crystal is carved with precision tools and sectioned into solar panels, which feed into a battery cell occupying the full interior of the thorax. The solar panels are then fitted flush over the thorax's top surface, sealing the power components seamlessly within the hull.
The navigational core is housed in the abdomen. A central mechanical assembly connects to ten axles - two to each side and six on the underside for the legs and wing mounts - and incorporates a magnetised compass needle on a pivot within a sealed casing. This is wired to the motor with spare connections reserved for the automaton core and radio receiver. Once the legs and wing ports are connected via dense rubber bands that allow independent articulation, the radio receiver is installed next: a delicate component requiring a careful hand to calibrate its frequency range before being slotted into a protective housing at the motor's front.
The eyes are made from carefully cut and polished clear quartz, shaped to replicate the ommatidia of the Odonata's compound eye and designed to capture light from any angle. Each lens is finished with a water-resistant copal lacquer to maintain optical clarity in adverse weather. Paired light-receiving sensors relay the funnelled input to the system. The automaton core - a Tier 3 unit sourced from Thalen & Wyck - is then seated within the Aerin head and connected to the receiver, compass, motor, and eyes before the head is sealed.
The antenna are wound from copper wire coiled over porcelain insulators, then connected to the full navigational array to complete the signal-receiving chain. Finally, the wings are constructed: each of the four is framed with steel poles, divided into four sections, and covered with copal-soaked silk stretched taut before Aerin plating locks the edges down. A counterweight at each wingtip provides stability in flight. The completed wings slot into the abdomen axles and are bound with rubber mounts that allow each to move fully independently. With all components assembled and sealed, the Luminarite cell is charged and a specialised radio tone is used to run the machine through its first operational commands.
Physical Characteristics
The Tradonata's main body spans roughly three feet in diameter with a total wingspan of five feet. Its predominantly Aerin construction gives it a distinctive shiny gold appearance, further ornamented with intricate etching and floral patterns across nearly every surface. Its glowing crystal eyes lend it an uncanny, almost mystical quality. In motion it is a busy sight - four wings beating in independent rhythms, six arms shifting and reaching, the head turning, the thorax flexing - an unmistakably mechanical creature that nonetheless moves with something approaching organic fluency.
Applications & Weaknesses
The Tradonata is built for one purpose: fast, discreet, and reliable parcel delivery. It hauls packages of up to ten pounds between pre-established pickup and drop-off locations across continental distances, flying high in cloud cover to avoid predators and interception. Its speed and agility are its primary defences.
They are, however, its only defences. The Tradonata has no combat capability and no meaningful structural resistance to damage - a solid hit will damage or destroy it outright. It also relies entirely on sunlight to power its Luminarite cell; in environments unable to supply adequate light, it will eventually shut down.
