First Claim
1. An autonomously navigated mobile platform comprising:
- 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 forgenerating 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.
