The prompt
Design a highly detailed, competition-ready FTC 2026–2027 BIOBUZZ robot for Team Error. Create a real 3D CAD model, not a concept image. Use a compact mecanum drivetrain with a rigid rectangular aluminum extrusion chassis, four mecanum wheels, motor mounts, cross-bracing, and a low center of gravity. Add a modular front intake, a guided internal game-piece transfer system, a compact storage mechanism, and an adjustable scoring assembly. Include realistic brackets, shafts, bearings, gears, belt or chain drives, servo mounts, battery tray, Control Hub mount, wiring clearance, and protective panels. Design every subsystem as a mechanically connected assembly with realistic proportions, clearances, mounting holes, and manufacturable geometry. Use parametric dimensions, modular construction, and lightweight components suitable for FTC robot fabrication and 3D printing. Provide a detailed isometric view and functional top, front, and side views. Make the design practical to assemble, maintain, and repair. IMPORTANT: Verify the official BIOBUZZ game-element dimensions and scoring requirements before finalizing the intake and scoring mechanisms. Do not invent game-specific dimensions. Keep the scoring mechanism modular until the rules are verified. Prioritize reliability, fast game-piece collection, accurate scoring, and easy maintenance.
