We'll implement the ergo jig for the 2024-26 season to simulate the cockpit area. In the ergo jig, we will finalize the bounding box based on measurements taken from a jig that is difficult to simulate in CAD:
Movement within occupants' cell
Roll Cage height
Helmet in occupant cell
Location of ergonomics components for a better experience
Minor simulation of egress
In the end of this project, our goal is to:
Max forearm-forearm width
The angle and position of the steering wheel
Position of seat
Pedal box longitudinal variation
Max torso space
Max leg space
Finalize the bounding box for the driver (Required for Frame to finalize roll cage height )
The specifics and considerations for designing can be seen from this document:

Design
Specifics of each component
Pedal Jig
Manufacturing Method: Wooden Panel that is held up by L-brackets that are mounted to t-slotted frame
Data Collection Method: Panel will be pushed forward or back depending on size of driver to find adjustability of leg pedal box
Seat
Manufacturing Method: Wooden Panels with bottom of the seat constrained with toe clamps
Data Collection: Seat will be adjusted based on frame that slides up or down
Steering Wheel
Manufacturing Method: Steering Wheel lasercut; mounted with 3D printed jig that attaches to the end of the frame.
Data Collection: Angle adjustable by tightening screws at L-brackets
