Abstract: A robotic device including one or more proximity sensing systems coupled to various portions of a robot body. The proximity sensing systems detect a distance of an object about the robot body and the robotic device reacts based on the detected distance. The proximity sensing systems obtain a three-dimensional (3D) profile of the object to determine a category of the object. The distance of the object is detected multiple times in a sequence to determine a movement path of the object.

Abstract: A method and apparatus for determining space occupancy and performing volumetric measurement of a transportation system using a time-of-flight (TOF) sensor array are provided. In the method and apparatus, the TOF sensor array, which is mounted in a transportation system and includes a plurality of TOF sensors, outputs a plurality of distance measurements made by the plurality of TOF sensors, respectively. In the method and apparatus, a map of one or more objects positioned in the transportation system is generated based on the plurality of distance measurements. The map is output for display to a user by a display.
