The prompt
Create a complete manufacturable CAD assembly of a Passive Dual-Axis Self-Leveling Platform using Gravity Roller + Differential Cam Mechanism. Overall dimensions: - Base: 550 × 450 × 70 mm, 30×30×3 mm MS frame - Top platform: 500 × 400 × 10 mm - Leveling range: ±15° pitch and ±15° roll - Design load: 20 kg Mechanism: Use a 2-axis gimbal system with outer and inner frames. Use Ø20 mm shafts with 6204 bearings. At the centre-bottom, create a Ø50 × 100 mm steel gravity roller with a 3–5 kg weighted mass, CG approximately 150–180 mm below the top platform. Create two perpendicular differential cam mechanisms, one for pitch and one for roll: - Cam: Ø160 mm × 12 mm - Bore: Ø20 mm - Base radius: 60 mm - Effective radius: 60–80 mm - Follower roller: Ø25 × 12 mm with Ø10 mm bearing - Follower/link pin: Ø10 mm - Upper link: 180 mm centre-to-centre - Lower link: 160 mm centre-to-centre - Link thickness: 8 mm, width: 25 mm - Follower displacement: ±25 mm Working mechanism: Inclined base → gravity roller shifts → cam rotates → roller follower moves → linkage moves → gimbal frame rotates opposite to base → top platform becomes horizontal. Make all shafts, bearings, pivots, spacers, brackets and fasteners as realistic separate parts. Use revolute joints and ensure there is NO motor, sensor, electronics, actuator or hydraulic system. Generate: 1. Full isometric assembly 2. Front/side/top views 3. Bottom cutaway showing roller + cams + followers + linkages 4. Exploded assembly 5. Detailed cam-follower close-up 6. Section view 7. Motion study at 0°, 10° and 15° inclination Make the internal mechanism clearly visible and mechanically connected. Prioritize realistic manufacturability and avoid component interference.
