TL;DR: This paper has developed a software system for autonomous navigation that provides for greater capability, and the entire system was tested in simulation, and a subset of the capability was demonstrated on a real vehicle.
Abstract: Autonomous cross-country navigation is essential for outdoor robots moving about in unstructured environments. Most existing systems use range sensors to determine the shape of the terrain, plan a trajectory that avoids obstacles, and then drive the trajectory. Performance has been limited by the range and accuracy of sensors, insufficient vehicle-terrain interaction models, and the availability of high-speed computers. As these elements improve, higher- speed navigation on rougher terrain becomes possible. We have developed a software system for autonomous navigation that provides for greater capability. The perception system supports a large braking distance by fusing multiple range images to build a map of the terrain in front of the vehicle. The system identifies range shadows and interpolates undersamples regions to account for rough terrain effects. The motion planner reduces computational complexity by investigating a minimum number of trajectories. Speeds along the trajectory are set to provide for dynamic stability. The entire system was tested in simulation, and a subset of the capability was demonstrated on a real vehicle. Results to date include a continuous 5.1 kilometer run across moderate terrain with obstacles. This paper begins with the applications, prior work, limitations, and current paradigms for autonomous cross-country navigation, and then describes our contribution to the area.

TL;DR: Experimental results of the proposed novel three-degree-of-freedom electromagnetic actuator for an image stabilization system for autonomous vehicles are described.
Abstract: Image deteriorations due to vibrations have become a problem in an autonomous system. Conventional image stabilization systems have some problems such as the increase in size. In order to solve the problems, we proposed a novel three-degree-of-freedom electromagnetic actuator for an image stabilization. This paper describes experimental results of the proposed actuator. The frequency characteristics are investigated, and the effectiveness of the actuator is discussed.

TL;DR: An autonomous vehicular system based on multi-agents to reduce the complexity of the autonomous system and can be applied for all vehicular brands, contradictory to the existing systems that were dedicated to specific brands.
Abstract: Since the 21st century, vehicles have attracted a great interest due to their potential applications for transportation of people and goods. The initial concerns of industries and researchers were that radio-equipped vehicles are able to keep the drivers informed about risks and road conditions. However, recent researches focuses more on providing the drivers with more comfort an less effort. For instance, air-conditioning, automatic features, GPS, etc, insure the quality of service (QoS) for the users. Moreover, the researches are still in advance to promote more autonomy and dynamic to the vehicle. In this paper, we present an autonomous vehicular system based on multi-agents to reduce the complexity of the autonomous system. In fact, instead of executing several tasks by one process, we split them between different agents. Therefore, this complexity reduction reduces the execution time and provide a quick intervention in complex scenarios. Furthermore, our multi-agent system can be applied for all vehicular brands. In contradictory to the existing systems that were dedicated to specific brands.

TL;DR: The experimental results show the capability of the proposed system to perform the task of autonomous road marks painting with accuracy of ±10 cm.
Abstract: The design and experimental works of an autonomous robotic platform for road marks painting are presented in this paper as the first autonomous system of its kind. The whole system involves two main sub-systems, namely: an autonomous mobile robot navigation system which is used for recognizing the roads and estimating the position of road marks, and automatic road marks painting system that is attached to the mobile robot platform to control the spray of the paint on the road’s surface. The experimental results show the capability of the proposed system to perform the task of autonomous road marks painting with accuracy of ±10 cm.

TL;DR: In this article, the authors present systems and methods for operating autonomous vehicles, including receiving an instruction for an autonomous vehicle to autonomously travel in an autonomous mode from a first location to a second location.
Abstract: The present disclosure provides systems and methods for operating autonomous vehicles. In one example embodiment, the method includes receiving an instruction for an autonomous vehicle to autonomously travel in an autonomous mode from a first location to a second location. When operating in the autonomous mode, the autonomous vehicle is restricted to operating within a limited operating envelope. The method includes receiving data indicative of a request by a human operator to operate the autonomous vehicle. In response to receiving the data indicative of the request by the human operator to operate the autonomous vehicle, the method includes authorizing the autonomous vehicle for operation by a human operator in a non-autonomous mode outside of the limited operating envelope. The limited operating envelope limits at least one operating capability of the autonomous vehicle based at least in part on an operating limit associated with an autonomous system for the autonomous vehicle.
