Abstract
Autonomous hospital delivery robot has been developed. The robot delivers X-ray films or medicines, etc. on behalf of the hospital staff. The robot determines the appropriate path to the given destination based on the preprogrammed geographical data, and moves autonomously. If the robot encounters persons or anything else on the way, the robot stops or avoids them safely, then heads for the destination again. Moreover, the robot takes elevators by itself, when needed. It has been verified that the autonomous movement is fully safe and reliable in hospital where unspecified people exist. This paper describes the autonomous movement and the system for delivery operation.
