Robofest 4WD Robot

Create a complete, professional, manufacturable 3D CAD model and assembly of a 4WD mobile robot for Robofest. Use mm, keep dimensions parametric/editable, and make the design mechanically realistic, symmetric, clean, and SolidWorks-compatible. Bottom chassis: 190 × 150 × 3 mm, R10 corners; front axle +65 mm and rear axle −65 mm from centerline (130 mm axle spacing). Use four yellow BO gear motors with separate motor brackets because the motors have no direct mounting holes. Do not screw through motor bodies. Use actual bracket dimensions where available; otherwise use parametric placeholders. Battery plate: 170 × 120 × 3 mm, R10 corners, centered above chassis. Keep it clean; no motor/axle/sensor/decorative holes. Add only required structural attachment holes after standoff positions are known. Electronics plate: 140 × 100 × 3 mm, R8 corners, centered above battery plate. For controller, motor driver, wiring and electronics. Add only 4 symmetric Ø3–4 mm structural standoff holes; keep the central area clear. Top plate: 120 × 80 × 3 mm, R8 corners, centered above electronics plate. For camera, sensors and lightweight components. Add only 4 symmetric Ø3–4 mm structural standoff holes; keep the center clear. Motor/wheels: Four yellow BO motors, two front/two rear, symmetric left/right. Align shafts with the ±65 mm axle lines. Include four wheels, suitable motor brackets, realistic ground clearance, and ensure no wheel/chassis interference. Camera: Fixed front-facing camera bracket on the top plate, centered/protected with clear forward view. Do not make it automatically adjustable. Plate stack: 190×150 bottom → 170×120 battery → 140×100 electronics → 120×80 top. Use suitable standoffs and enough clearance for battery, electronics, wiring, motors and camera. Engineering: No random holes/cutouts. Don't invent unknown component dimensions; use clearly marked parametric placeholders. Maintain edge distances, symmetry, component clearance and manufacturability. Fully constrain sketches, use symmetry/mirroring where appropriate, avoid over-definition, dangling references, self-intersections and zero-thickness geometry. Ensure all features rebuild successfully. Output: Individual editable parts for plates, motor brackets, wheels, camera bracket and standoffs; complete assembly; dimensioned engineering drawings. Save SLDPRT parts, SLDASM assembly, STEP/STP universal CAD files, and STL only when needed for 3D printing. MOST IMPORTANT: Do not randomly redesign or change the established architecture, plate dimensions, proportions, axle positions, or overall robot design. If something is unknown, use a parametric placeholder instead of guessing.

This model was generated without adjustable parameters. Open it in the editor to add your own dimensions.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
