Abstract
The increasing demand for precision, efficiency, and safety in hospital pharmacies has led to a growing interest in automation, particularly through the use of artificial intelligence (AI)-powered robotic systems. These robots are designed to streamline the drug dispensing process by reducing human error, optimizing inventory, and improving turnaround times in medication distribution. This study investigates the implementation and operational benefits of AI-driven robots within hospital drug dispensing units, highlighting their integration with pharmacy management systems, automated storage, barcode scanning, and error detection technologies. The manuscript presents a synthesis of research studies, hospital case reports, and early adopters to assess the impact of such systems on medication accuracy, operational efficiency, and patient safety. The study further reviews challenges associated with cost, training, and system integration while outlining a methodology for evaluating robot performance in a hospital setting. The analysis concludes that while the technology was nascent at the time, AI-powered drug dispensing robots held significant promise for transforming hospital pharmacy operations through precision-driven, automated support systems.
