Contenido principal del artículo
Resumen
Este trabajo aborda el problema de la localización eficiente de emisiones de metano en espacios abiertos mediante el uso de robótica móvil. En contraposición a los métodos convencionales que emplean detectores puntuales, o que empleando medidores de rango dependen del suelo como reflector natural (los cuales conllevan largos tiempos e ineficientes trayectorias de inspección), se propone un enfoque robótico que aumenta la eficiencia de la toma de datos. Para ello se monta un detector de rango sobre una unidad pan-tilt que apunta continuamente a un robot móvil que actúa como reflector artificial, permitiendo tomar medidas sobre el plano horizontal. Este enfoque permite abarcar grandes superficies en cortos espacios de tiempo sin perder resolución espacial. Los resultados obtenidos en un área experimental de 140 m2 validan la efectividad de este enfoque para la rápida detección y localización de fuentes de emisión de gas metano.
