Fusion 360: Parametric Engineering CAD Model of OvAR Rover (Based on Traxxas Maxx) Ended

Project Objective
Create a fully parametric, engineering-grade 3D CAD model of the OvAR Rover using the Traxxas Maxx RC platform as the foundational chassis. The model must be built exclusively in Fusion 360 and structured for future upgrades including additional sensors, electronics housings, LiDAR, camera masts, and protection components.
This is NOT a cosmetic model. It must be dimensionally accurate and mechanically plausible, enabling future modification and integration work.

Software Requirement
Fusion 360 only. No other CAD packages.
Deliverables must include:
• Fusion 360 native file (.f3d)
• STEP (.stp)
• STL (for quick previews)

Deliverables
1. Accurate Digital Model of Traxxas Maxx Base Platform
Designer must model the following with correct proportions, dimensions, and mounting geometry:
• Main chassis frame
• Upper and lower chassis decks
• Bulkheads
• Shock towers (front and rear)
• Suspension arms (upper and lower)
• Steering link area
• Wheel hubs, carriers, knuckles
• Gearbox/transmission outer housing (simplified, no internal gears required)
• Driveshafts (simplified)
• Battery tray
• Motor mount region
• All visible mounting hole patterns and anchor points

High accuracy is required because future components will mount based on these reference geometries.

2. OvAR Rover Modular Components (Fusion 360 Parametric Bodies)
Include simplified placeholder components sized to dimensions we provide or approximate:
• Electronics bay (Jetson Orin, Pixhawk, battery packs)
• Top-deck expansion plate for AV hardware
• 360-vision camera mast
• Front/side/rear sensor mounts
• LiDAR mount
• Protective panels or housings (simple extruded forms, not detailed enclosures)

All custom parts must be parametric, with editable dimensions and clean sketches.

3. Assembly Structure and Constraints
• Logical component hierarchy (bodies, components, sub-assemblies)
• Proper fusion joints or motion links where applicable
• Suspension components should be movable (recommended but optional)
• All custom components must be placed accurately relative to the chassis

4. Required Modeling Standards
The designer must follow professional CAD standards:
• No merged bodies unless logically required
• No mesh imports from STL files
• No broken features or suppressed geometry
• Fully editable sketches and feature tree
• Clean parametric naming: “Chassis_Base,” “Front_Arm_Lower,” “LiDAR_Mount,” etc.
• No hidden, unnecessary, or internal geometry unrelated to the project

This ensures future designers can update or extend the rover without rebuilding from scratch.

5. View Outputs
Provide the following:
• Exploded view of major components
• Sectional view through chassis and electronics bay
• Clearance check around sensor mounts
Inputs We Will Provide
• Traxxas Maxx reference images and dimension references
• Dimensions of Jetson Orin, Pixhawk, LiDAR, RealSense cameras
• Sketches showing intended mounting locations
• Any missing measurements needed (designer is expected to request these proactively)

Designer should request clarifications early rather than making assumptions.

Level of Detail Required
This is a baseline engineering model, not a manufacturing-ready assembly.
Included:
• Accurate external geometries
• Structural components
• Mounting points
• Placeholder components for electronics

Not required:
• Internal gearbox gears
• Screw threads
• Material textures
• Ornamental detailing

Timeline
Estimated completion: 10–20 days
Faster delivery acceptable, but quality and accuracy are mandatory.

Designer Requirements
• Strong, demonstrable Fusion 360 capability
• Experience with robotics, RC platforms, or mechanical assemblies
• Ability to create clean, editable, parametric models
• Ability to work with incomplete data and request missing measurements read less
