A lift-plus-cruise UAV, seed-delivery module, and field station designed together around return, refill, recharge, and traceable missions.
R1 develops a reforestation aircraft and its field station as one system. A winged lift-plus-cruise configuration carries a removable seed module. The ground station captures the aircraft, transfers an identified batch, and restores pack energy before another authorized mission.
The design addresses the interfaces between flight, material handling, local control, and the service record. An operator retains intervention authority, while immediate flight recovery and mechanism stops remain local.
The selected airframe has a 2.60 m span, four vertical lift units, and a dedicated cruise propeller. The central hopper shortens the material path and places the changing payload close to the design centre of gravity. A 50-pellet nominal batch is the standard recipe; the larger hopper capacity remains a design limit rather than an automatic range claim.
An intermediate cup counts and weighs the batch before transfer. Cup loss is compared with aircraft gain. A mismatch, incompatible lot, or uncertain residual material holds the system rather than treating a commanded release as a completed delivery.
Charging requires a compatible pack profile, permitted connection state, and thermal conditions. Completion follows pack and charger acceptance criteria. Connector engagement and retained restraints block departure even when other launch inputs appear ready.
The package records 160 executed Python guard checks covering service, charge, launch, failure states, and all combinations of seven service guards. Seven STEP models, four DXF sets, and two native KiCad placement studies connect the logic to a selected physical layout.
Mission energy and reserve figures come from a declared arithmetic model. They support sensitivity review; they do not establish measured endurance. The source’s three-sortie trace is a scripted illustration, not a flight simulation or physical operation.
The record distinguishes planned, attempted, sensor-confirmed, and ground-verified placement. A restoration specialist owns species, provenance, density, season, and site suitability. Ground observations link deposition to emergence and survival; a delivered pellet count cannot become a tree count.
The source is a resolved narrative design exercise. No aircraft or PCB was fabricated, and no physical flight or ecological trial occurred. Images are original concept visualizations or model-derived drawings. Software checks validate reference predicates only; native PCB files are unrouted placement studies.
