This study presents the development of a patient-transfer robot to provide safe and convenient transfer ofelderly and disabled individuals by incorporating a driving-assistance module to enable mobility. To addressthe challenges faced in transferring, as well as mobility by caregivers of elderly and disabled individuals, therobot was designed to operate safely during movement by addition of a driving module thereby enhancinguser convenience. Operational tests were conducted to evaluate the performance of the patient-transfer robotwith driving assistance. In the load test for patient transfer, the system demonstrated stability and durabilityby successfully lifting maximum load of 120 kg to the maximum transfer height. In the driving stability test,the robot carried maximum load of 120 kg over 5 m and stopped without significant tilting, thus confirmingits driving stability. Results of this study confirmed that the patient-transfer robot system withdriving-assistance functions operated stably while performing transfer and driving tasks. Future researchswhould focus on expanded testing and field demonstrations to conduct performance evaluations and usabilityassessments. Through these improvements the product would eevolve into a convenient and reliable caresolution for elderly individuals and their caregivers across medical and healthcare settings.
