BACKGROUND This study aims to compare the efficacy and safety of the Ahmed glaucoma valve (AGV) with the Baerveldt glaucoma implant (BGI) in glaucoma patients. METHODS Databases were searched to identify studies that met pre-stated inclusion criteria, involving randomized controlled clinical trials (RCTs) and non-randomized controlled clinical trials. Treatment effect was analyzed using a ran...

This paper proposes a new obstacle avoidance algorithm for the CONTROLAB AGV which uses a similar strategy adopted by a blind person to avoid obstacles while walking. The AGV moves within an office environment with a known floorplan and uses an "electronic stick" consisting of infrared sensors to detect unknown obstacles. Initially a global potential field function is defined for each floorplan...

Trajectory tracking is an essential capability of robotics operation in industrial automation. In this article, an artificial neural controller is proposed to tackle trajectory-tracking problem of an autonomous ground vehicle (AGV). The controller is implemented based on fractional order proportional integral derivative (FOPID) control that was already designed in an earlier work. A non-holonom...

In this paper, we consider real-time tracking of an Autonomous Guided Vehicle (AGV) in an indoor industrial scenario. An on-board odometer provides information about the dynamic state of the AGV, allowing to predict its pose (position and orientation). At the same time, an external Ultra Wide Band (UWB) wireless network provides the information necessary to compensate the error drift accumulate...

Due to globalization and the growth of international trade, many container terminals are trying to improve performance in order to keep up with demand. One technology that has been proposed is the use of Automated Guided Vehicles (AGVs) in the handling of containers within terminals. Recently, a new generation of AGVs has been developed which makes use of cassettes that can be detached from the...

In pursuit of flexible and agile automation within the domain of discrete manufacturing, a paint-shop with its surrounding logistics and handling processes is under construction as a laboratory prototype application. Holonic Manufacturing is argued to be a promising strategic paradigm and architecture to use for a system characterized by flexible production logistics and control. This paper des...

units output by some cells have to be carried to other units. An automated guided vehicle (AGV) is a vehicle which carries the units among the cells by moving around in a space which is composed of guidepaths. The space is logically composed of space objects structured in a tree, where high-level space objects denote broader and more abstract space. In this paper, we would like to model the mov...

Due to poor predictability of resources and difficulty in perception task execution status, traditional Automatic Guide Vehicle (AGV) scheduling systems need a lot extra time the charging process. To solve this problem, digital twin-based dynamic AGV (DTDAS) method is proposed, including four functions, namely knowledge support system, model, optimization, simulation. With features virtual real...
