Valet Market Autonomous Store

A.I. Powered Cashierless Retail Infrastructure & Sensor Integration

Project Overview

Valet Market San Diego served as a flagship capital project for Accel Robotics, pushing the boundaries of autonomous, frictionless retail. In this high-tech environment, specialized physical hardware must interface perfectly with AI-driven sensing systems to track inventory in real-time.

As a Lead Systems Engineer, I was responsible for the end-to-end development of the specialized shelving hardware, ensuring rigorous adherence to thermal requirements and durability standards while maintaining a seamless aesthetic.

Technical Contributions

  • Smart-Shelf Arrays: Engineered multi-modal shelving units using 4 high-precision weight sensors per shelf, achieving a detection accuracy of **+/- 3mm**.
  • Pusher Mechanisms: Designed custom "pusher" assemblies that provided physical staging for products while acting as a mechanical trigger for AI camera activation.
  • Hybrid Detection: Integrated weight-sensing and computer vision arrays (Weight + Vision) to verify item removal and replacement with high confidence.
  • Thermal Management: Managed hardware specification for refrigeration and freezer units to ensure component longevity under continuous thermal load.
