Abstract—This review of human–robot interaction technology (HRI) suggests how retailers can enhance customer service and improve their operations through the use of service robots. We have reviewed earlier studies and have identified current and emerging robotic technologies as potential retail game changers in business. The review of HRI technologies presents actionable information that can help retailers stay relevant with consumers during their technological development of the service system. Although extensive research has investigated the psychological, neurological, and engineering issues of HRI, few studies have established how robot technology can elevate customer service and transform the retail industry. This study explains the technological innovations that enable autonomous robots to offer unique consumer experiences that have noteworthy potential for assisting elderly and physically challenged consumers. This study covers primary HRI applications that can transform retail, entertainment, travel, and service business today.
