Abstract
In one embodiment, an autonomously navigated mobile platform includes a support frame, a projector supported by the frame, a sensor supported by the frame, a memory including a plurality of program instructions stored therein for generating an encoded signal using a phase shifting algorithm, emitting the encoded signal with the projector, detecting the emitted signal with the sensor after the emitted signal is reflected by a detected body, associating the detected signal with the emitted signal, identifying an x-axis dimension, a y-axis dimension, and a z-axis dimension of the detected body, and one or more of a range and a bearing to the detected body, based upon the associated signal, identifying a present location of the mobile platform, navigating the mobile platform based upon the identified location, and a processor operably connected to the memory, to the sensor, and to the projector for executing the program instructions.
