Project Summary: This project develops and validates a heterogeneous autonomous delivery system that integrates a Chrysler Pacifica AV with a Unitree Go2 quadruped robot. The Pacifica serves as a mobile hub, transporting the Go2 to rural delivery zones via a built-in ramp, after which the robot autonomously navigates the final leg and completes package handoff. Over 12 months, the team will produce ROS 2 communication software, terrain-adaptive navigation algorithms, payload management hardware, and a validated field performance. All software will be released open-source. This proof-of-concept is designed to enable a larger-scale Major Research Initiative on rural autonomous logistics.
