TL;DR: This letter proposes a novel solution to this decision-theoretic planning problem that directly obtains the continuous value function with only the first and second moments of the transition probabilities, alleviating the requirement for an explicit transition model in the literature.
Abstract: Motion planning under uncertainty for an autonomous system can be formulated as a Markov Decision Process with a continuous state space. In this paper, we propose a novel solution to this decision-theoretic planning problem that directly obtains the continuous value function with only the first and second moments of the transition probabilities, alleviating the requirement for an explicit transition model in the literature. We achieve this by expressing the value function as a linear combination of basis functions and approximating the Bellman equation by a partial differential equation, where the value function can be naturally constructed using a finite element method. We have validated our approach via extensive simulations, and the evaluations reveal that to baseline methods, our solution leads to in terms of path smoothness, travel distance, and time costs.

TL;DR: The theory and recursive procedures method of fault-tolerant system construction is applied to a decentralized self-organizing autonomous robotic system that forms a circle and the result of simulation shows the usefulness of the proposed method.
Abstract: Constructing a system capable of functioning without any human support over an extended period is the aim of many engineers. However it is generally considered to be difficult to make decentralized self-organizing autonomous system fault-tolerant. In this paper, we propose to apply the theory of highly structured self-diagnosable systems to this problem. As an example, we apply the theory and recursive procedures method of fault-tolerant system construction to a decentralized self-organizing autonomous robotic system that forms a circle. The result of simulation shows the usefulness of the proposed method. The highly structured self-diagnosable system has an O(|E|)fault-identification algorithm that can diagnose each of the units in the system independently, locally and in any order, where E and |E| mean the set of the directed edges and its cardinality, respectively.

TL;DR: In this article, an autonomous system for transporting an item from a first location to a second location includes an autonomous vehicle and a trailer, and the vehicle and trailer are configured to transport the item to the first location, the trailer is configured to transfer the item from the trailer to the autonomous vehicle, and then the vehicle is configurable to transport it to the second location.
Abstract: An autonomous system for transporting an item from a first location to a second location includes an autonomous vehicle and a trailer. The autonomous vehicle includes a compartment, a vehicle sensor, a vehicle drive mechanism, a vehicle power source, and a vehicle control module for controlling the vehicle drive mechanism. The trailer includes a hitch for connecting the trailer to the autonomous vehicle, an electrical system, a trailer sensor in communication with the electrical system, a trailer power source in communication with the electrical system, a storage space, and a mechanism for autonomously transferring the item from the storage space into the compartment of the autonomous vehicle. The autonomous vehicle and trailer are configured to transport the item to the first location, the trailer is configured to transfer the item to the autonomous vehicle, and the autonomous vehicle is configured to transport the item to the second location.

TL;DR: In this paper, the authors describe the experiences of deploying distribution ring network self-healing control system in China, including the architecture designing, retrofitting with advanced controller, simulating and testing on site.
Abstract: This paper describes the experiences of deploying distribution ring network self-healing control system in China, including the architecture designing, retrofitting with advanced controller, simulating and testing on site.This decentralized self-healing system consists of nine sets of edging controllers Easergy T300 installed on 20kV feeders. These modular-designed T300s are fully integrated into ring main unit (RMU) switches. It is important specially for existing RMU upgrading that extra space is not needed.These controllers are connected using peer to peer (P2P) communication to build an autonomous system. The principle of the self-healing grid automation system is to start an automatic sequence of re-energizing the healthy part of the MV ring after a short circuit or earth fault somewhere in the ring. The re-energizing operations have to be performed in a minimum time with a maximum of safety and security. No distribution management system (DMS) is required and no operator intervention is needed.To validate this decentralized self-healing system, there are two steps: in the lab, special test bench can verify the whole system which is almost same as a real system just except communication network; on site, a dedicated simulator can be used to "generate" a short circuit fault, then switches are operated automatically according to self-healing algorithm in the real communication network.The project was implemented for State Grid Corporation of China. The main objectives of this program are to improve the feeder automation capability and enhance reliability of power supply in the CBD area of Hangzhou. This self-healing control system help our utility customer to achieve their goals.
