The prompt
Create a detailed engineering 3D CAD concept of an original experimental drone named “MECH-MORPH X1”. IMPORTANT: This is NOT a conventional quadcopter. The aircraft has ONE central A2212 1800KV BLDC motor as the primary propulsion source. Mechanical power is distributed from the central motor through a belt-driven central shaft and four bevel-gear transmission units to four rotors. Four N20 geared motors are NOT used as propulsion motors. Each N20 controls the mechanical pitch angle of one rotor using a lead-screw, sliding collar and linkage mechanism. The four rotor pitch mechanisms allow differential aerodynamic control. Design the complete drone as a real manufacturable mechanical prototype rather than a sci-fi decoration. Main dimensions: - Overall frame: approximately 400 mm × 400 mm - Central mechanical gearbox: approximately 110 mm × 110 mm × 50 mm - Four symmetric rotor arms - Target total mass: 550–650 g - 3S 11.1 V battery - One A2212 1800KV BLDC motor - Four N20 geared motors - Metal shafts and standard ball bearings - 3D-printable structural components - Use M2/M3 fasteners where appropriate Mechanical architecture: A2212 BLDC → belt drive → central shaft → four bevel-gear outputs → four rotor shafts. Each rotor must contain: rotor shaft → rotor hub → variable-pitch linkage → sliding collar → lead screw → N20 geared motor. Make the pitch-control mechanism clearly visible and mechanically believable. The central gearbox should be partially transparent or shown in an exploded view so the complete power transmission can be understood. Create: 1. Full assembled isometric view 2. Top view 3. Side view 4. Front view 5. Exploded mechanical assembly 6. Close-up of one rotor pitch-control module 7. Close-up of central gearbox 8. Internal mechanical transmission view 9. Dimensioned engineering-style drawing Design requirements: - Symmetrical center of gravity - Battery mounted close to the geometric center - Bearing-supported rotating shafts - Replaceable mechanical modules - Easy disassembly for handmade construction - 3D-printable parts separated into printable components - Avoid impossible intersections between gears, shafts and linkages - Include realistic clearances between moving parts - Keep high-speed rotating components mechanically enclosed where possible - Do not use four independent propulsion motors - Do not turn this into a normal quadcopter - Do not add unnecessary futuristic parts that have no mechanical function Visual style: real aerospace engineering prototype, exposed mechanical transmission, precision-machined shafts, gears, bearings and linkages, functional 3D-printable engineering design, highly detailed CAD assembly, realistic proportions, clean industrial prototype appearance. The final design should communicate a genuinely unusual mechanical propulsion and control architecture, not a normal consumer drone.
