In this article, a single application is suggested to determine the position of vehicles using Geographical Information Systems (GIS) and Geographical Position Systems (GPS). The part of the article material included mapping three dimensional coordinates to two dimensional coordinates using UTM or LAMBERT geographical methods, and the algorithm of conversion of GPS information into GIS maps is ...

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...

Manufacturing Flexibility is the ability of a manufacturing system to respond, at a reasonable cost and appropriate speed, to planned or unplanned changes in external or internal environments. It is accomplished by multidimensional attributes of the manufacturing system. In the global, rapidly changing modern market conditions manufacturing flexibility becomes a necessity in many industrial env...

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...

Automatic Guided Vehicles or AGVs are increasingly being used in manufacturing plants for transportation tasks. Optimal scheduling of AGVs is a difficult problem. A learning AGV is very attractive in a manufacturing plant since it is hard to manually optimize the scheduling algorithm to each new situation. In this paper we compare four reinforcement learning methods for scheduling AGVs. Q-learn...

Fuzzy logic inference system (FIS) has been widely applied to the controller design for automatic guided vehicles (AGV) because FIS allows easier controller design under uncertainty and nonlinearity (Hwang et al., 2007; Godjevac & Steele, 1999; Baturone et al., 2008; Er &Deng, 2004; Ng & Trivedi, 1998). Wall following is a commonly adopted scheme for an AGV to navigate in the indoor or outdoor ...

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 jobsho...
