Mechanism CAD
Mechanism CAD - 3D Model Exploration
Before we write any code, we need a physical mechanism. If you don't have a previous robot or mechanism to use, below are 3D models of mechanisms you can build affordably.
Interactive 3D model of the Flywheel mechanism.
Interactive 3D Models
Flywheel Mechanism
This is the mechanism you'll be programming in this workshop. Use your mouse to orbit the model, zoom in and out, and examine the design from different angles.
Arm Mechanism
The arm version of the workshop mechanism. You'll use it to practice precise positioning and control, which come up on nearly every FRC robot.
File Format Guide
STL Files
Standard format for 3D printing. Compatible with most slicers including PrusaSlicer, Cura, and Bambu Studio.
STP Files
CAD format for editing and modification. Opens in Fusion 360, SolidWorks, and other CAD software.
Arm Mechanism - Bill of Materials
💡 Cost-Saving Tip: Many parts listed below can likely be built from scrap material or parts you already own from previous projects, significantly reducing the actual cost of this mechanism.

What's Next?
Ready for Programming
Now that you have a mechanism, the next step is connecting the hardware and writing the code to run it. We'll cover the motors, sensors, and controllers needed to bring this CAD model to life.
