I will convert your cad assembly into a urdf for ros and gazebo
Rosnoah
About this gig
Need your robot to actually move in simulation not just sit there as a dead mesh? I convert your CAD into a clean, working URDF that loads and behaves correctly in ROS, Gazebo, and RViz.
Most CAD designers can't build a proper URDF, and most ROS developers struggle with clean CAD. I do both so your joints, frames (TF), meshes, and physics are set up the way a robotics engineer actually needs.
What you get:
- A properly structured URDF / xacro (links, joints, limits)
- Optimized visual + collision meshes (no laggy sims)
- Accurate mass, center of mass, and inertia values
- A model verified in RViz / Gazebo tested, not guessed
- Motion demo video + ROS 2 launch file (Premium)
Why me:
I'm a mechanical engineering student who builds ROS 2 stacks and race-car hardware, so I understand both the physical design and the software side.
What I need from you:
Your CAD in STEP, STL, or Fusion 360. No CAD yet? I can model it from scratch (add-on).
Before ordering, please message me with your files or requirements so I can confirm scope, timeline, and price. Every robot is different let's make sure it's a great fit first.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

I turn CAD into simulation-ready robot models — the rare mix of solid mechanical design and real ROS knowledge. Most CAD designers can't build a working URDF, and most ROS developers can't do clean CAD. I do both.
I can help with:
• CAD assembly to clean URDF/xacro for ROS, Gazebo & RViz
• Robot & mechanical part modeling in Fusion 360
• Fully parametric, editable assemblies
I'm a mechanical engineering student who builds ROS 2 stacks and race cars, so I know what a sim model needs. Clear scope, fixed price, fast communication — send your files and I'll tell you how I'd approach it.
FAQ
What do you need from me to get started?
Your CAD in STEP, STL, IGES, or Fusion 360, plus a quick note on which parts move and how (the joints). No CAD yet? I can model it from scratch as an add-on. Message me first and I'll confirm it all fits.
Which ROS version do you support?
The URDF/xacro itself works in both ROS 1 and ROS 2. I build and test in ROS 2 (e.g. Humble/Jazzy), and the Premium package includes a ROS 2 launch file. Need a specific distro? Just tell me before ordering.
Will it work in Gazebo, or only RViz?
Basic delivers a clean model that loads in RViz. Standard and Premium add accurate inertials (mass/CoM/inertia) and are verified to spawn and behave correctly in Gazebo. Premium also includes a motion demo video.
