During material handling processes, automated guided vehicles (AGVs) pose a path conflict problem. To solve this problem, we proposed multi-objective scheduling model based on total driving distance and waiting time, used the A* planning algorithm to search shortest of AGV. By using speed control strategy, were able detect overlap time. Additionally, adopted an efficient MapReduce framework imp...

With the trend of terminal automation and requirement for port operation efficiency to be greatly improved, it is very necessary optimize traveling route automatic guided vehicles (AGV) with reference connection loading unloading equipment. As a complex multi-equipment system, inevitable that AGV will collide when due various accidents in actual operation, which lead locking reduce operation. C...

In this paper, the blockage problem of optical link between AGV (autonomous ground vehicles) and AP (access point) in logistics–warehousing VLC (visible light communication) network is analyzed. First, based on random geometric model, a link-blockage model proposed. Given position AGV, obstacle, state can be obtained through model. Then, an AP-placement scheme Under placement, AGVs any have rel...

This paper presents a new absolute position measurement method using pseudo-random binary sequences. This encoding technique has the notable advantage of requiring only one code-symbol per quantization interval. This compact encoding method offers an economical solution to very-highresolution absolute position applications: shaft encoders, linear encoders, and "automated guided vehicle" (AGV) n...

Energy efficiency plays an increasingly important role not only in supply chains, but also in-plant systems. Manufacturing companies are using energy-efficient material handling equipment to solve their tasks. A new example of this effort is the use drones for transportation small components. Within frame article, a AGV-drone joint model described. The service AGV-based milkrun trolleys and mak...

The aim of this project is to construct a Bluetooth (2.4GHz) and vision controlled auto guided vehicle (AGV) for use during the COVID-19 pandemic. can be maneuvered by using an application in mobile phone or function. function following label that affixed on user. communication was applied control AGV at maximum distance 10 m. carry kg load. system could track follow human movement with label. ...

PURPOSE The purpose of this study was to evaluate the intermediate surgical results of Ahmed glaucoma valve (AGV) implantation in patients less than 7 years of age, with advanced primary congenital glaucoma who have failed previous surgeries. PATIENTS AND METHODS Consecutive patients with advanced primary congenital glaucoma that failed previous operations and had undergone subsequent AGV imp...

Automated, underground freight transport should enable sustainable economic growth in the Amsterdam area in the Netherlands. An innovative transport system, which guarantees reliable logistics and which avoids congestion problems, is currently being developed. This logistics system will be highly automated, using AGVs (Automatic Guided Vehicles) for transport and automated loading and unloading...
