In this work, the measurement and improvement of drivers' attitudes are aimed by using data obtained from driving experiences in virtual traffic which is created by the 3D game platform and is enriched by assisting with the Personal Traffic Lights (PeTraLi). For this multi-user simulation which can also be seen as a serious game, vehicles for drivers, driverless vehicles, intersections equipted with...
In the modern world of today, technology means everything. It comes in many shapes and sizes: from tablets, smartphones, laptops, cars that drive themselves and flying drones. The world around us is becoming more and more interested in new inventions. With this, there is a growing need for innovations to help firefighters, doctors, automotive and people from other areas. The paper presents an alternative...
The software used to control autonomous vehicles is a type of embedded system that needs to undergo strenuous testing before deployment. Field testing is the final stage of testing ensuring that autonomous vehicles show the intended behavior. It usually does not take into consideration the code structure. In this context, a previously proposed testing model and a software tool to support structural...
Despite improvements in work zone safety, injuries and fatalities remain a significant problem for work zone personnel. Crew and vehicles are often protected with the use of a vehicle located at the rear of the work zone, which is fitted with a mechanism to attenuate the impact energy of a vehicle. This vehicle, called an impact attenuation, or crash cushion, vehicle, is designed and placed to be...
The paper presents innovative, reconfigurable simulator of mobile robots included in anti-crisis operations system. The simulator development is a part of the PROTEUS project. Along the whole anti-crisis system is developed, the simulator of mobile robots is constructed. Majority of the simulators developed worldwide are intended for specific vehicles and used for various applications of particular...
The use of autonomous vehicles is becoming ubiquitous due to the versatility and flexibility that they display in the execution of individual and cooperative tasks, coupled with the fact that their use avoids placing human lives at risk. Closely related to these autonomous systems and their control are the simulation tools. A poor control design could have dramatic consequences to the vehicle itself,...
The Department of Defense's future vision for Network Centric Operations (NCO) will increase combat power by networking relevant entities across the battlefield. This will result in highly complex mission scenarios in which the operator's workload will be easily overloaded if the system is not designed to support the mission requirements. New technologies for these complex command and control environments...
This paper presents a cost-effective approach to design an embedded autopilot system for a 4-rotor aerial vehicle. The system is targeted for autonomous control research, and it consists of an onboard system and a ground station. The onboard system interfaces with the vehicle and provides data link for sensor measurements and control data. The ground station provides a user-friendly interface for...
In June 2009, Memorial University of Newfoundland began a project involving multiple disciplines of its Faculty of Engineering and Applied Science exposing students to the many aspects of autonomous vehicle development. Combining the skills of teams from the disciplines of Ocean and Naval Architecture, Electrical, and Mechanical engineering, students were able to design and build a prototype of an...
The Iver2 Autonomous Underwater Vehicle remote helm functionality provides an open system interface, which allows users to easily integrate their own sensors, and take full control over the vehicle in real time. The remote helm option provides a separate CPU to communicate with the main vehicle control CPU. The remote helm API provides all the commands when interfacing the Iver2 to a user control...
A flexible modular robotic software environment based on the popular MRPT toolkit is reported in this paper that is able to integrate path planning, navigation and control algorithms easily from several sources. The different modules (which are responsible for SLAM, trajectory tracking, sensor and actuator handling, visualization etc.) communicate with each other via a carefully developed network...
This paper describes an investigation into the cooperation of multiple autonomous underwater vehicle system( MAUVS). A distributed control architecture MOOS-IvP (which was proposed by Newman at Oxford and Benjamin at MIT) is applied. In this approach, fully distributed control of underwater vehicles is realized and behavior-based control strategy is used to ensure a timely reaction of the vehicles...
This paper presents an object-oriented world model for the road traffic environment of autonomous (driver-less) city vehicles. The developed World Model is a software component of the autonomous vehicle's control system, which represents the vehicle's view of its road environment. Regardless whether the information is a priori known, obtained through on-board sensors, or through communication, the...
We present an interface for controlling mobile robots that combines aspects of graphical trajectory specification and state-based programming. This work is motivated by common tasks executed by our underwater vehicles, although we illustrate a mode of interaction that is applicable to mobile robotics in general. The key aspect of our approach is to provide an intuitive linkage between the graphical...
This paper presents the architecture and design concept of a low-cost, light weight, computational framework intended primarily for the navigation of small autonomous vehicles. The proposed system integrates GPS, inertial sensor, magnetometer and range-finder modules together with a high-performance microcontroller. Debugging facilities and various data communication and storage facilities are proposed...
The test bed for the Measurement Science Program at the National Institute of Standards and Technology (NIST) includes a robot arm on a rail, conveyers, mannequins and a custom designed automated guided vehicle (AGV). The NIST AGV includes an onboard personal computer and control software, safety sensors, and an absolute positioning sensor system among other useful and research tools, sensors and...
In this study, a simulation based regression analysis for rack configuration of an autonomous vehicle storage and retrieval system (AVS/RS) is presented. We develop a mathematical function for rack configuration of an AVS/RS that reflects the relationship between the output (response) and the input variables (factors) of the system. In the regression model, the output is the average cycle time for...
Stereo vision system is a practical method for depth gathering of objects and features in an environment.
