Autonomy through interaction - The JPL telerobot interactive planning system

Abstract: The telerobot interactive planning system (TIPS) has been developed to provide automated task planning and reasoning for satellite servicing in NASA's Jet Propulsion Laboratory telerobot testbed. The strategy taken in this development is that an interface between a partially autonomous system and external sources of knowledge is a feature which enables application of technology not yet fully autonomous. Interactive features, both between the operator and TIPS and among the reasoning engines within TIPS, result in a system which has greater robustness than the reasoning engines alone could provide.

Block-chain-based distributed and partitioned power network data processing system and method thereof

Abstract: The invention discloses a block-chain-based distributed and partitioned power network data processing system and a method thereof. The system comprises at least one block chain autonomous system, at least one decision and control center communicatively connected with the at least one block chain autonomous system, and a plurality of data access bodies communicatively connected with the at least one block chain autonomous system, wherein the block chain autonomous system is composed of a plurality of data trusted nodes; the block chain autonomous system shares the technical data from the data access main body therein; the decision and control center obtains technical data from any data trusted node in the block chain autonomous system according to the granted service rights. The distributedand divided domain data processing method based on the block chain provided by the invention effectively improves the speed and efficiency of the block confirmation, improves the throughput of the system and reduces the system delay, saves the computing resources of nodes, and improves the confidentiality, integrity and usability of the technical data of the power network.

Feedback control for non-linear singular systems

Abstract: An invertible non-linear map is developed, which transforms a non-linear singular system into a regular one and preserves local properties under the application of specific feedback control laws. The presented algorithm is easily implementable on a digital computer, since it is of closed form. An application of the above algorithm is presented on an autonomous vehicle.

A flexible hardware-in-the-loop architecture for UAVs

Abstract: As robotic technology matures, fully autonomous robots become a realistic possibility, but demand very complex solutions to be rapidly engineered. In order to be able to quickly set up a working autonomous system, and to reduce the gap between simulated and real experiments, we propose a modular, upgradeable and flexible hardware-in-the- loop (HIL) architecture, which hybridizes the simulated and real settings. We take as use case the autonomous exploration of dense forests with UAVs, with the aim of creating useful maps for forest inspection, cataloging, or to compute other metrics such as total wood volume. As the first step in the development of the full system, in this paper we implement a fraction of this architecture, comprising assisted localization, and automatic methods for mapping, planning and motion execution. Specifically we are able to simulate the use of a 3D LIDAR endowed below an actual UAV autonomously navigating among simulated obstacles, thus the platform safety is not compromised. The full system is modular and takes profit of pieces either publicly available or easily programmed. We highlight the flexibility of the proposed HIL architecture to rapidly configure different experimental setups with a UAV in challenging terrain. Moreover, it can be extended to other robotic fields without further design. The HIL system uses the multi-platform ROS capabilities and only needs a motion capture system as external extra hardware, which is becoming standard equipment in all research labs dealing with mobile robots.
