Tracked Rover SDF Assembly

Create a **realistic, editable multi-part CAD assembly** of an autonomous tracked ground vehicle using the uploaded reference images. **Overall size:** exactly **300 × 180 mm (L × W)**. Nothing may exceed this envelope. **Chassis:** * Two independent continuous tracks. * Central electronics mounting plate. * Tracks must remain unobstructed and freely rotatable. * Use Image 1 as the main chassis reference. **Component layout:** * **Front (X 0–90):** centered Raspberry Pi Camera; MQ-8 on front-right. * **Center (X 90–210):** Raspberry Pi. * **Rear (X 210–300):** L298N on rear-left; GPS on rear-right. * Keep weight approximately balanced. **Camera:** X 25–45, Y 0, height 60–80 mm, facing forward, clear FOV, adjustable ±15° bracket. **MQ-8:** X 55–85, Y +45 to +65, height 20–40 mm; sensing mesh upward and fully exposed; removable M3 mount. **Raspberry Pi:** X 120–200, Y −25 to +25, height 10–20 mm; horizontal on 4 M2.5/M3 standoffs; all ports/GPIO/camera connector accessible and ventilated. **L298N:** approx. 43 × 43 mm; rear-left, X 235–280, Y −45 to −5; 4 M3 standoffs; terminals and heatsink accessible; wiring paths to both motors. **GPS:** rear-right, X 235–275, Y +25 to +65; antenna facing upward; raised 20–30 mm; unobstructed and removable. Add **M3 mounting holes/slots, cable-tie holes, cable guides and realistic cable routing**. Never route cables through tracks. Use simple manufacturable geometry suitable for **3D printing/CNC/laser cutting**. Keep all parts separate and editable: **Chassis, Left Track, Right Track, Electronics Plate, Raspberry Pi, Camera + Mount, MQ-8 + Mount, L298N + Standoffs, GPS + Mount, Cable Management, Hardware.** **Final check:** 300 × 180 mm maximum, no collisions, no floating parts, tracks rotate freely, camera FOV clear, GPS/MQ-8 unobstructed, connectors accessible, and all mounting geometry mechanically feasible. Export as an **editable STEP-compatible multi-part assembly**.

Parameters

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.
