DUROBOT—Delivery Series is an intelligent robot that facilitates contactless delivery in a 3D space, improving delivery efficiency and service quality. The robot is powered by LiDAR and Binocular Vision Fusion technologies, which equip it to plan paths in 3D space. The device can flexibly navigate narrow corridors with widths as small as 55 centimeters. The robot is standardized and modular, which makes it easy to refit and operate. It combines multiple AI technologies to offer full-process contactless delivery. This is especially important under the COVID-19 epidemic situation. Thanks to the robot, user health is better protected, and they can experience the warmth and reliability of this technology.
