This document describes the design and manufacturing of an autonomous cart capable of following a user. The cart uses a Microsoft Kinect sensor to recognize and track users through voice and gesture recognition. An Arduino microcontroller controls the cart's motors to follow the user while avoiding obstacles. Two prototypes were created, with the second using stronger aluminum wheels, an acrylic base, and improved Kinect mounting. The cart aims to autonomously follow a single identified user based on their commands, maintaining distance and navigating obstacles. The document evaluates the cart's stress resistance and discusses challenges in accurate human tracking and autonomous navigation.
