Abstract
An autonomous personal service robotic apparatus, such as a robotic golf caddy, including a drive assembly for movement of the robotic caddy, a digital computer having memory devices in which are stored a digital map and navigation rules, and having a operations program for the control of performance of personal services, including movement and navigation of the caddy in the environment, and a position determination assembly for determining the position of the robotic device in the environment. The position determination assembly also dynamically determines the position of unmapped elements in the environment and super imposes or overlays them with the mapped elements and position of the robotic apparatus. Position preferably is determined by differential GPS techniques. The navigational rules for the robotic device control its movement in the environment in response to its sensed position in the mapped environment, the sensed unmapped elements and preferably the sensed relative position of the user. A method of providing an autonomous, personal services robot which is well suited to provide a robotic golf caddy.
