3D LiDAR ScanBox
Portable, repeatable product scanning with an iPhone
Overview
A modular scanning unit that synchronizes an arched phone sweep with a turntable to generate detailed 3D models from multiple heights and angles.
01
A controlled path around the object
I led the design of the arched arm and custom components that hold the iPhone, ring light, and turntable. The phone moves through three heights as the object rotates, collecting overlapping views for Rapid Robotics software to stitch into a model.

From rack-and-pinion to pulley
The first rack-and-pinion concept proved harder to assemble and introduced avoidable friction. A dual-pulley revision improved motion control, lowered the electronics, and simplified the travel-ready structure. Wood prototypes established geometry before the final acrylic build.
