JUSTIN YIN / ENGINEERING PORTFOLIO FRC / 2026

SELECTED ROBOTICS WORK · 2026

Built in CAD.
Made to move.

I’m Justin Yin. This is a closer look at the robot systems I designed for FRC: from individual mechanisms to the full assembly, with the actual CAD files behind the work.

01 / THE WORK

A robot is more than a final render.

The design record matters. My source archive contains native SolidWorks assemblies, STEP exports, manufacturing files, and multiple saved versions of the 2026 robot. This site shows the mechanisms and keeps the underlying files within reach.

03 / SELECTED MECHANISMS

Inside the robot.

Each design thread is grounded in the supplied CAD archive. The images marked “STEP projection” are generated from geometric points in the actual export files.

Intake system

The intake assembly appears in both the 3.5 and 3.7 robot folders. A native SolidWorks assembly and a STEP export make this mechanism directly inspectable.

Turret revisions

The archive preserves separate turret V2 and V3 assemblies, with V3 also present in the later 3.7 robot folder. The version trail is part of the work.

Hopper assembly

A separate hopper assembly and STEP export appear in the 3.5 robot files. The geometry preview here is generated from that export.

INTEGRATION / 04

From parts to robot

Full robot assemblies are saved in the 3.5 and 3.7 source folders. Intake, turret, hopper, chassis, and climb subassemblies sit within that wider design record.

04 / INTERACTIVE CAD STUDY

Rotate the real geometry.

These points come from the Cartesian geometry in my STEP exports. Drag to turn the model. This is a geometric preview rather than a shaded surface render.

05 / UNDERLYING FILES

Inspect the source.

The archives contain native SolidWorks parts and assemblies, plus STEP, DXF, and STL exports. These selected files can be opened independently to inspect the geometry and fabrication output.

ARCHIVE NOTES

Additional native assemblies in the supplied files include turret V2/V3, elevator and carriage, a June 28 intake assembly, and full robot assemblies from the 3.5 and 3.7 folders. The July 13 archive also holds manufacturing exports for individual parts and a full assembly STEP file; the latter is too large for this site's direct download. Standard and vendor components in the source archives belong to their respective makers.

06 / ABOUT

Design is a record
of decisions.

I’m Justin Yin. I use CAD to move from an idea for a mechanism to a buildable robot system. This portfolio is a direct view into my FRC 2026 design files and the iterations preserved within them.
