Project Summary

In order to be able to test seating positions more reliably, I designed and fabricated a modular ergonomics jig using aluminum T-slot extrusion to accurately replicate the cockpit environment. The jig allows for precise, repeatable adjustment of seat position, pedal reach, steering location, and driver interface geometry, enabling quantitative evaluation of ergonomics across multiple drivers. By manufacturing the jig in-house, I ensured rapid iteration, high stiffness, and reconfigurability, ultimately improving driver comfort, control consistency, and confidence while informing final cockpit and control layout decisions.

Validation and Final Results

• Successfully allowed for rapid seat position testing

• Free rotating steering wheel enables "snap steering" tests between drivers

• Held up to extensive and repetitive testing

• Easily disassembled for storage and use in future seasons
