This paper presents navigation system for an omni-directional AGV (automatic guided vehicle) with Mecanum wheels. The Mecanum wheel, one design for the wheel which can move in any direction, is a conventional wheel with a series of rollers attached to its circumference. The localization techniques for the general mobile robot use basically encoder. Otherwise, they use gyro and electronic compas...

Purpose. To evaluate the efficacy of Ahmed Glaucoma Valve (AGV) implantation in patients with refractory glaucoma in a tertiary hospital in Brazil. Methods. Retrospective case series of patients who underwent AGV implantation. Primary outcome was to assess the rate of failure, which was defined as intraocular pressure (IOP) in two consecutive visits greater than 18 or lower than 5 mmHg (criteri...

PURPOSE Ahmed glaucoma valve (AGV) implant is an aqueous shunt device used to control intraocular pressure in glaucoma. Implant failure results from impervious encapsulation of the shunt plate causing increased hydraulic resistance and raised intraocular pressure. We hypothesized that deregulation of fibrosis pathway contributes to capsular resistance. We tested this by studying fibrosis relate...

The Komodo project concerns the handling of multiple real-time events by Java threads that are supported by a multithreaded Java microcontroller. The architecture of the processor core and resulting implications are considered. The use of thread-based event handling is introduced and explained in combination with an Automatic Guided Vehicle (AGV) application. The advantages of thread-based even...

Automated guided vehicles (AGVs) have been part of every production plant because the increasing demand for speed, efficiency and throughput. Therefore, an AGV is automation system in plants. In that sense, AGVs can be considered as programmable configurable robots has specific performance requirements such positioning accuracy, maximum load, safety standards. this study, comprehensive paramete...

In this study, we present and discuss a variant of the classical vehicle routing problem (VRP), namely heterogeneous multitype fleet green automated guided (AGV) with time windows (HFGVRPTW) applied in workshops flexible manufacturing systems (FMS). Specifically, based on analysis AGV body structure motion state, transport distance energy consumption are selected as two optimization objectives....

A modified particle swarm optimization (PSO) approach is presented for the multi-mode resource-constrained scheduling problem of automated guided vehicle (AGV) tasks. Various constraints in process AGV system are analysed, and types quantities AGVs as allocable resources considered. The multiple-AGV combined distribution mode its impact on tasks also Finally, a task model established which obje...

We designed and implemented a fork-type automatic guided vehicle (AGV) with a laser guidance system. Most previous AGVs have used two types of guidance systems: magnetgyro and wire guidance. However, these guidance systems have high costs, are difficult to maintain with changes in the operating environment, and can drive only a pre-determined path with installed sensors. A laser guidance system...

To analyse an automated guided vehicle (AGV) system operating under selected vehicle routeing strategies, we present a simulation model that can handle an arbitrary system layout as well as arbitrary numbers of AGVs and pedestrians causing congestion in the system. We introduce a dynamic vehicle routeing strategy based on hierarchical simulation that operates as follows: at the time of each AGV...

We consider a manufacturing system that uses Automated Guided Vehicles (AGVs) for material handling. Increasing the capacity of the AGVs used can lead to increased throughput and reduced inventory-holding costs. However, AGVs are typically expensive. Hence modeling the economics of buying an additional vehicle is an important problem from the standpoint of making a system lean. Optimization of ...
