The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a 3D real-time range camera is the subject of this paper. Our approach has been tested successfully on British safety standard recommended object sizes and materials placed on the vehicle path. The segmented (mapped) obstacles are then v...

This paper suggests a routing method for automated guided vehicles (AGVs) in port terminals by using a Q-learning technique. One of the important issues for the efficient operation of automated guided vehicle system (AGVS) is to find the shortest time route instead of the shortest distance route which is usually being used in practice. For the estimation of the travel time, the waiting time mus...

Abstract This paper proposes SSM (Sensor Steering Mechanism) for a lateral guided vehicle with an articulated body. Authors demonstrated the simple lateral guiding method SSM for the front wheel steer type, the reverse phase four-wheel steer type and the rear wheel steer type vehicle. SSM presents the stable lateral guiding performance for automated vehicle which follows a straight and curved p...

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....

This paper discuses sensor steering mechanism (SSM) for a laterally guided vehicle with a rear wheel steering mechanism. The authors have demonstrated the geometry of SSMs for front wheel steering type and reverse phase four-wheel steering type vehicles. SSMs allow stable lateral guiding performance for automated vehicles following a path with straight and curved portions created by a guideway....

This paper deals with the on-line design of a supervisor to coordinate an automated guided vehicles (AGV) fleet. This supervisor ensures the system safeness (no collision) and a good coordination between vehicles (no blocking situations). It is the least restrictive, and ensures controllability and nonblocking. We propose a compositional procedure to resolve this problem allowing an efficient o...

In this paper, we study the design and control of automated guided vehicle (AGV) systems, with the focus on the quayside container transport in an automated container terminal. We first set up an event-driven model for an AGV system in the zone control framework. Then a number of layouts of the road network (guide-path) are carefully designed for the workspace of the AGVs in a container termina...

This paper presents the motivation behind the new joint NIST/IEEE Virtual Manufacturing Automation Competition (VMAC). This competition strives to take the Automated Guided Vehicle (AGV) user community driven requirements and turn them into a low-entry-barrier competition. The objectives, scoring, performance metrics, and operation of the competition are explained. In addition, the entry-barrie...

In this paper, a study on detectability and readability of barcodes using omnidirectional vision system for automated guided vehicle is presented. Images from omnidirectional camera are known to be distorted against the height of the object. We present an algorithm for detecting and reading barcodes successfully without correcting the image distortion. Experiments were conducted both when the A...

Localization and navigation technology is one of the key technologies for Automated Guided Vehicle (AGV). In this paper we develop an AGV navigation system utilizing commercial Bluetooth GPS. WGS-84 coordinates system is converted to space rectangular coordinate system, which is combined with orientation information, initial position and gesture of AGV can be determined. Experimental result sho...
