Dispositivo para asistir la navegacion robótica de un vehículo en ambiente ruidoso, que comprende un arreglo de micrófonos dispuesto en el vehículo, un procesador de señales que filtra y acondiciona las señales obtenidas, las cuales son restringidas a un rango audible del ser humano, y además las procesa y clasifica, detectando los ambientes según su sonido, y genera restricciones a los límites máximos y mínimos de velocidad lineal y angular del vehículo; método asociado

摘要

The invention relates to a device and a method for assisting the robotic navigation of a vehicle in a noisy environment, where the device comprises an arrangement of microphones provided in the vehicle for capturing both the internal and external sound of said vehicle; and an analog-to-digital signal processor that filters and conditions the signals obtained from the arrangement of microphones, which are restricted to a hearing range of the human being, between 300 and 20,000 Hz, rejecting frequencies below 300 Hz and over 20,000 Hz, by means of programable band-pass filters. Furthermore, the processor processes and classifies the signals, detecting the environments according to the sound thereof, by means of neuronal networks of the feed-forward type; and generates restrictions on the maximum and minimum speed limits of the vehicle, both linear and angular, for the control of the vehicle.
