Abstract

Un vehículo de manipulación de materiales incluye una cámara, un módulo de odometría, un procesador y un mecanismo de accionamiento. La cámara captura imágenes de un identificador para un pasillo del sistema de estantería y una porción de la pata del estante en el pasillo. El procesador utiliza el identificador para generar información indicativa de la posición inicial de la pata del estante y el espacio entre las patas del estante en el pasillo, generar una posición inicial del vehículo utilizando la posición inicial de la pata del estante, generar una posición basada en la odometría del vehículo utilizando los datos de la odometría y la posición inicial del vehículo, detectar una pata del estante posterior utilizando una imagen capturada, correlacionar la pata del estante posterior detectada con una posición esperada del vehículo utilizando el espaciado de la pata del estante, generar una señal de error de odometría basada en una diferencia entre las posiciones y actualizar la posición basada en la odometría del vehículo utilizando la señal de error de odometría y/o compensación de balanceo del mástil generada para usarse en la protección del extremo del pasillo y/o la localización dentro/fuera del pasillo.
