Optimus Prime G1
Full Simulation Engine v17.0 — Build a 3D-printable, servo-driven Optimus Prime robot in Autodesk Fusion 360 with 9 kinematic simulation modules.
Full Simulation Engine v17.0 — Build a 3D-printable, servo-driven Optimus Prime robot in Autodesk Fusion 360 with 9 kinematic simulation modules.
An open-source Autodesk Fusion 360 simulation suite that programmatically builds a fully-articulated, 3D-printable Optimus Prime G1 robot and runs a 9-module kinematic simulation — all driven remotely via the Model Context Protocol (MCP).
This project brings the legendary Autobots leader from the Transformers franchise to life — from the 1984 Generation 1 animated series — as the first fully working 3D-printable CAD model of Optimus Prime with complete servo-driven kinematic simulation, robot-to-truck transformation, and FDM-printable hardware integration.
140+ bodies across 19 assemblies — torso, head, pelvis, arms, legs, backpack, ion blaster, and more. Every component modelled with real hardware integration.
18× MG996R (9.4 kg·cm) + 6× MG90S (1.8 kg·cm) with exact cavities, mounting brackets, and wire channels pre-cut.
Full 9-stage transformation sequence with interference checking. Animate robot-to-truck-to-robot seamlessly.
ROM test, head scan, wave, breathing, walking, running, combat, transformation, stability analysis — all with collision detection.
0.60 mm FDM clearance, Y-axis midplane splitting, M3 screw holes, Ø6.4 mm magnet pockets, and cable routing channels pre-integrated.
Export to STL (3D printing), STEP (CAD/CAM), URDF (ROS/Gazebo), and F3D (Fusion 360 archive).
Clone the repository, enable MCP in Fusion 360, and run the simulation in 2 minutes.

This project is inspired by Optimus Prime, the iconic leader of the Autobots from the Transformers franchise created by Hasbro/Takara in 1984. The G1 design from the original animated series and the live-action movies serves as the aesthetic foundation for this first fully working 3D-printable CAD model.
