Sonar system for remote vehicle

摘要

A SONAR system for use with a robotic vacuum having SONAR emitters and receivers thereon. The SONAR system comprises a waveguide or horn located in front of the emitters and receivers that can improve the overall target resolution and reduce the number of “dead zones” where targets are not easily resolved.

1. A SONAR system for use with a remote vehicle, the SONAR system comprising:
at least one SONAR emitter having a waveguide tuned to guide emitted sound from the emitter into an environment of the remote vehicle; and at least two SONAR receivers, each SONAR receiver having a waveguide tuned to receive reflected sound from an environment of the remote vehicle, wherein each of the waveguides of the emitter and the receivers includes a front wall, a rear wall, a top wall, and a bottom wall, and at least one of the waveguides is tuned by varying a curvature of its front and rear walls and/or its top and bottom walls.
