Robot Drivebase | 2025 | Created using Onshape Part of my job as CADD Lead for FRC Team 569 is creating a CAD model which replicates our actual robot. That way, I can prototype and envision subsystem designs before our mechanical team actually constructs it. This is useful for saving time, resources, and money. I was able to make a 3D model of our robot in Onshape. I couldn't find an extruded aluminum model, so I made my own tool which generates extruded aluminum. You can choose its length and fillet radius. The battery holder I modeled was also connected using mate connectors. Other parts common to FRC Robots, like the swerve drive and PDH, were imported from a CAD library. Finally, I used constraints in the sketching face such that, if the perimeter or overall structure is ever required to be changed, the model will automatically update to fit its new measurements. Below is an example of this.
