115 Lincoln Laboratory automated four Husky Mark III mine-detection vehicles, the world’s first autonomous vehicles to steer using a novel localizing ground-penetrating radar. At nine tons, these autonomous vehicles are some of the largest to be put into combat operations to date. The vehicle is guided by a novel derivation of the pure pursuit steering algorithm adapted to a proportional four-w...

An effective approach to dynamic obstacle avoidance for mobile robots is described in this paper. The main concepts in this approach include local Polar Object Chart (POC) for defining possible ways out, obstacle definition, detour mode, anchor for preventing getting lost, steering delimiting and velocity delimiting. The presented concepts and methods were tested and verified both by simulation...

Abstract: This paper proposes a tracking control method for a certain type of differential-drive wheeled mobile robot, called automated guided vehicles (AGVs), using a continuous mode approach of sliding mode control (SMC). The SMC applied produces a continuous signal in between the U and –U control signals instead of discrete ones. The controller is applied to control the velocity and directio...

This paper aims the development of autonomous obstacle avoidance algorithm for automated guided vehicle with a Kinect sensor. To do this task, the followings are executed. Firstly, depth data is obtained from the Kinect sensor, and the mean filter approach is developed to filter out noises. Secondly, Otsu and U-V parallax based method is designed to identify background and obstacles. Finally, A...

A fuzzy approach to collision avoidance for automated guided vehicle (AGV) navigation is proposed. Static obstacles with no a priori position information as well as moving obstacles with unknown trajectories are considered in this study. Intuitive and subjective human ideas of collision avoidance are modeled into fuzzy rules. Fuzzy logic is applied in the inference procedure for AGV navigation,...

<p>Automated Guided Vehicle (AGV) is a type of vehicle that driverless and programmed to run on predetermined route transfer loads. Thus, the aim this work improve layout, operation, maintenance. results these objectives explain many are used in AGV systems for modern material handling due ability technology increase efficiency productivity system reduce human labor. Flow paths or layouts...

This paper proposes a new design for a bi-directional automated guided vehicle (AGV) system, in which two AGVs can exchange their loads, their scheduled transportation tasks, and even their vehicle numbers when they move in opposite directions. With this load-exchangeable AGV (EX-AGV) system, common problems such as conflicts and deadlocks will not occur; therefore, the load of an AGV is always...

We compare two approaches for a Markovian model in flexible manufacturing systems (FMSs) using Monte Carlo simulation. The model, which is a development of Fazlollahtabar and Saidi-Mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (AGV), namely, the reliability of machines and the reliability of AGVs in a multiple AGV jobs...

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...

The purpose of this article is to investigate the potentials of implementing an integrated Automated Storage and Retrieval System (ASRS) and Automated Guided Vehicle System (AGVS) in maritime container terminals. We first define the main components of the proposed configuration and justify the potential impacts of each and that of the integrated system. A 3D simulation (and animation) model is ...
