Industrial Crawler Robot CAD Design

3D CAD Modeling & Mechanical Design for 4-Wheeled Industrial Crawler Robot. Project Overview:
We are seeking an experienced Mechanical Engineer / 3D CAD Designer to create a complete, detailed 3D CAD model of a 4-wheeled industrial magnetic crawler robot.
The robot is designed for heavy-duty industrial surface traversal. You will be responsible for creating the structural chassis, wheel assembly mountings, motor/gearbox integrations, and overall vehicle layout.
Scope of Work:
Develop a full 3D CAD assembly of the 4-wheeled crawler robot.
Design motor mounts, gearbox interfaces, wheel drives, and internal component layout.
Ensure realistic mechanical clearances, proper assembly hierarchy, and design for manufacturability (CNC, sheet metal, 3D printing).
Create clean render images of the final robot from multiple angles.
Key Deliverables:
Source CAD Files: Native assembly files (SolidWorks, Fusion 360, or Inventor).
Universal Files: .STEP and .IGES formats for manufacturing and distribution.
Renderings: High-resolution 3D visual renders (PNG/JPEG).
Assembly Drawing: Basic exploded view / layout diagram.
Note to Freelancers:
Full technical specifications — including exact motor & gearbox dimensions, wheel specs, target payload geometry, and structural requirements — will be provided to the selected freelancer upon project kickoff.
Required Skills:
3D Modeling & CAD (SolidWorks, Fusion 360, PTC Creo, etc.)
