Enhancing depth cues with AR visualization for forklift operation assistance in warehouse.

With warehouse operations contributing to the major part of logistics, architects tend to utilize every inch of the space allocated to maximize the stacking space. Increasing the height of the aisles and narrowing down the aisle-aisle space are major design issues in doing so. Even though forklift manufacturing companies introduced high reach trucks and forklifts for narrow aisles, forklift operators face many issues while working with heavy pallets. This thesis focused on developing a systemthat uses Augmented Reality(AR) to aid forklift operators in performing their pallet racking and pick up tasks. It used AR technology to superimpose virtual cues over the real world specifying the pallets to be picked up and moved and also assist in operating the forklift using depth cues. This aims to increase the productivity of the forklift operators in the warehouse. Depth cues are overlaid on a live video feed from a camera attached to the front of the forklift which was displayed using a laptop to the participants. To evaluate the usability of the system designed, an experiment was conducted and the performance results and the feedback from the participants was evaluated. A remote controlled toy forklift was used to conduct the experiment and a motion tracking system was set-up to track the cab and pallet. Simple pallet handling tasks were designed for the participants and their performance and feedback was collected and analysed. This thesis shows how AR offers a simple and effecient solution for the problems faced by forklift operators while performing pallet handling tasks in warehouse

Sistema mecatrónico automatizado de levantamiento y transporte de canastillas

Trabajo de Investigación TecnológicaEl levantamiento y transporte de carga en muchos sectores de Colombia se realiza de manera artesanal ocasionando posturas erróneas, causando problemas de salud principalmente en la columna como displasias lumbares o desgaste de articulaciones. Por esta razón, en este trabajo se diseñó un montacargas eléctrico operado de manera remota, usando conceptos de electrónica de potencia, electrónica análoga, comunicaciones digitales y radiofrecuencia que controlan los motores y llantas como medio de tracción y tomando como base el funcionamiento de un montacargas de gasolina que ofrecen los fabricantes a nivel mundial; para dar cabida al prototipo funcional, cuyas medidas partieron de las dimensiones de una canastilla plástica con un peso máximo de 60 kg.1 RESUMEN 2 INTRODUCCIÓN 3 PLANTEAMIENTO Y FORMULACIÓN DEL PROBLEMA 4 OBJETIVOS 5 JUSTIFICACIÓN 6 ANTECEDENTES 7 MARCO TEÓRICO 8 METODOLOGÍA 9 DISEÑO 10 IMPLEMENTACIÓN 11 PRUEBAS DEL PROTOTIPO 12 CONCLUSIONES 13 RECOMENDACIONES Y TRABAJOS FUTUROS 14 BIBLIOGRAFÍA 15 ANEXOSPregradoIngeniero Electrónic

Sistema para Identificação e Acoplamento de um AGV a uma Plataforma de Transporte Móvel

A atualidade tem revelado que o transporte de cargas na Intralogística é uma tarefa em permanente inovação. A introdução de AGV (Automated Guided Vehicles) no processo de transporte, veio revelar melhoria de resultados na eficiência da indústria e distribuição, libertando o homem para processos mais diferenciados na produção e distribuição. Tendo-se verificado que já existem soluções para o transporte de cargas na Intralogística, constatou-se que as mesmas não são totalmente autónomas. Como tal, surgiu a necessidade de implementar um sistema de navegação e identificação, que permitisse fazer o acoplamento de um AGV a uma plataforma de transporte, sem que fosse necessário o recurso a mecanismos orientadores. No âmbito de uma parceria estabelecida entre a Introsys S.A e a FCT – UNL, propõe-se nesta dissertação um sistema de identificação e navegação de uma rack, a qual deverá possuir 3 tags que a identificam. O sistema proposto foi simulado para se poder validar e determinar critérios como luminosidade do ambiente, dimensão das tags e a que distância o sistema é capaz de fazer um correto acoplamento. Os resultados obtidos demonstraram que o sistema teve uma taxa de sucesso de 100%, em 40 posições diferentes, para uma luminosidade de 8 focos de luz e uma dimensão de tag de 10x10cm, até uma distância de 4,5 metros. Concluiu-se que o sistema proposto é um sistema capaz de fazer um correto acoplamento a uma plataforma de transporte, desde que nesta estejam instaladas as tags propostas e sejam conhecidas as dimensões da plataforma de transporte.Present times have revealed that the transport of loads in Intralogistics have been a task in permanent innovation. The introduction of AGV (Automated Guided Vehicles) in the transport process has shown an improvement in the efficiency of industry and distribution, giving more freedom to workers to perform more differentiated processes in production and distribution. Having verified that there are already solutions for cargo transportation in Intralogistics, it was found that they are not completely autonomous. Therefore, the need to implement a navigation and identification system arose, which would allow the coupling of an AGV to a transport platform without requiring the use of guiding mechanisms. Within the scope of a partnership established between Introsys S.A and FCT - UNL, this dissertation proposes a rack identification and navigation system. The rack must have 3 tags that identify it. The proposed system was simulated in order to validate and obtain criteria such as, ambient brightness, tag sizes and at which distances the system is capable of making a correct coupling. The results obtained, showed that the system had a 100% success rate in 40 different positions, for a luminosity of 8 spotlights and a 10x10cm tag dimension, up to a distance of 4.5 meters. It was concluded that the proposed system is capable of making a correct coupling of a transport platform as long as the proposed tags are installed and the dimensions of the transport platform are known
