Abstract

Nowadays, robots and autonomous vehicles play a significant role in both daily life and industrial production. In many cases, these vehicles are required to automatically follow a predefined object or person. This paper presents the design of an autonomous vehicle capable of real-time object tracking using ultra-wideband radio technology combined with the polar coordinate method. The system consists of three ultra-wideband transceivers: two mounted on the vehicle acting as reference points (called Anchor nodes), and one attached to the target object (called the Tag node). Based on the polar coordinate system, the onboard positioning system determines the Tag’s location, and the drive system then guides the vehicle toward the target. Experimental evaluations demonstrate that the vehicle can accurately track and follow the object in real time. The results also indicate that when the vehicle moves at speeds below 4 km/h, the tracking path deviation remains within 20 cm. With the achieved specifications, the design is suitable for integration into target-following control systems for robots and autonomous vehicles used in civilian applications.
