Quiero desarrollar un dron agrícola capaz de cargar 250 L de producto y trabajar sobre terrenos planos de forma completamente autónoma. El corazón de la aeronave será un motor bóxer de dos cilindros que funcione como generador híbrido (nafta + baterías) para garantizar vuelo continuo con plena carga. Necesito que la estructura y los sistemas de a bordo estén optimizados para dos tareas principales: fumigación de cultivos y siembra de precisión. Ambos modos deben activarse y regularse desde la misma suite de control, con dosificación ajustable en tiempo real y registro de datos de aplicación. Busco un profesional o equipo que cubra: • Ingeniería y dimensionamiento del fuselaje, depósito de 250 L, brazos, rotores y tren de aterrizaje. • Selección e integración del power-train híbrido (motor bóxer, generador, controladores y packs de baterías) con redundancia y balance de peso. • Electrónica y software de vuelo autónomo (Pixhawk/ArduPilot, ROS, o equivalente) con planificación de misiones, geocercas y retorno seguro. • Sistema de fumigación y siembra intercambiable, calibrado y compatible con líquidos de distinta viscosidad y semillas de distinto calibre. • Planos 3D (SolidWorks o similar), lista de materiales, cálculos de resistencia y consumo, y manual de montaje para producción en serie limitada. Aporto especificaciones agronómicas y pruebas de campo; tú aportarás el diseño validado y la puesta a punto lista para prototipo funcional. Si dominas aerodinámica, CAD/CAM, electrónica de potencia y control autónomo, me gustaría avanzar cuanto antes.

The trickiest part of this job is the hybrid power system; getting 30-40 minutes of flight on a 250L payload with both gasoline and batteries is a tight constraint that dictates everything else. I will build the drone frame as a unified structure, probably in sections using CAD and then 3D modelling to get the exact shapes, then I will machine it from aluminum stock, so the generator motor fits snug inside the main chassis and the battery packs can be mounted below for stability. The 250L tank will be custom molded, also in CAD, so it fits perfectly within the internal volume and keeps the center of gravity low during flight. I would pick the tank first, so I know its exact dimensions and weight distribution before I start on the main fuselage engineering, also the arms and rotors will be sized using SolidWorks simulations for optimal lift and stability. I will automate the fumigation and seeding systems with adjustable flow rates and data logging, controlling them from a single interface. 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status. What is the maximum weight for the entire system including payload and fuel?
