Title: Robert Holt and Precision Calibration for Automated Vehicles.

Introduction

Robert Holt is an inventor associated with Blacksburg, Virginia, and Torc Robotics, Inc. His patent work addresses the precise positioning and orientation calibration of sensors used in automated vehicles.

Latest Patents

Holt is associated with 1 patent: “Precision Multi-Point Sensor Position and Attitude Calibration Brackets.” The invention describes systems, methods, and apparatuses that use calibration targets mounted on a bracket attached near the sensor being calibrated. A two-target bracket can be positioned near a GNSS antenna, while a three-target bracket can be placed near an inertial measurement unit, such as in the passenger cabin or on the vehicle chassis.

The targets have retroreflective surfaces that return signals, including infrared signals, to a theodolite or total station. Preprogrammed offset values identify the relative positions of the sensor and the targets, supporting accurate calibration of sensor position and attitude.

Career Highlights

Holt’s patent reflects work on a practical calibration approach for automated-vehicle sensors. By placing targets near the relevant sensor and accounting for their offsets, the system is designed to support precise measurements across different sensor types and vehicle locations.

Collaborations

Holt is associated with Torc Robotics, Inc. His listed coworkers include Joseph Fox-Rabinovitz and Alexander Little.

Conclusion

Robert Holt’s patent focuses on a multi-point bracket system that helps calibrate GNSS and inertial sensors for automated vehicles, contributing a targeted approach to vehicle sensing accuracy.
