What is Synthesis?

Synthesis is a robotics simulator designed to help FIRST Robotics teams design, strategize, test, and practice. Teams can import their own robot designs or use pre-existing ones into the simulator for a variety of uses. 

What is Synthesis Code Emulation?

The Synthesis code emulator allows users to run their own Java or C++ code on virtual robots within the Synthesis simulation engine. Synthesis must be installed before downloading the emulator.


Synthesis is currently under development and is continuously improving and adding new features. Here are some of the features Synthesis currently has:

  • Export any CAD model from Autodesk Inventor or Fusion 360 as a robot.
  • Export any CAD model from Autodesk Inventor as a field.
  • Simulate any exported robot model in a custom field environment
  • Real-time physics collisions using Bullet Physics
  • Custom mode for driver practice and strategy
  • Practice competitions with Local Area Network Multiplayer
  • Mix and Match mode for creating custom robot designs
  • Customizable controls
  • Java and C++ code emulation
  • 100% open source
  • Field and Robot library available for download
