Patent number: 10805396Abstract: A method and apparatus are provided for autonomously detecting and reporting anomalies in actions of an autonomous mobile node, or in behaviors of a swarm of autonomous mobile nodes to an operator. The autonomous mobile node may experience anomalies or unexpected situations due to various failures or external influence (e.g. natural weather phenomena, enemy threats). During a training phase a prediction model and a structured model may be established from measurement data received from one or more sensors of an autonomous mobile node or a swarm of nodes while executing an action or behavior under normal circumstances. A prediction model forecasts the expected outcome of an action or behavior, and structured model helps quantify the similarity of a learned action or behavior to the currently observed situation. Based on the measurement data applicable models can be used for an action or behavior for anomaly detection in the action or behavior.Type: GrantFiled: September 12, 2018Date of Patent: October 13, 2020Assignee: EpiSys Science, Inc.Inventors: Nadeesha Oliver Ranasinghe, Bong Kyun Ryu, Wei-Min Shen

Patent number: 10645170Abstract: Techniques for autonomously establishing, maintaining, and repairing of a wireless communication network among multiple autonomous mobile nodes (AMN) are provided. The multiple AMNs are flown towards a first node. A tentacle is established with the first node and extended to cover a second node over a distance, thereby establishing a wireless communication network between the first node and the second node via the multiple AMNs. Any damage to the established wireless communication network or tentacle may be autonomously detected and repaired by using spare AMNs. Further, the communication network may be used to enable autonomous detection, tracking of the second node, as well as autonomous detection of a contamination area, based on data received from one or more sensors onboard the AMNs deployed in the air.Type: GrantFiled: December 30, 2017Date of Patent: May 5, 2020Assignee: EpiSys Science, Inc.Inventors: Nadeesha Oliver Ranasinghe, Bong Kyun Ryu, Wei-Min Shen

Patent number: 6636781Abstract: Systems and techniques are described for distributed control and coordination of autonomous agents in a system. A protocol for distributed control allows autonomous agents to negotiate a group task for the agents, such as locomotion or self-reconfiguration in a robot application, and to synchronize individual agent actions to effect the group task. A protocol for adaptive communication allows autonomous agents, such as physically coupled self-sufficient robot modules, to continuously discover changes in their local topology. In general, in one implementation, the technique includes: discovering a local topology, which includes a type of a communication connection to autonomous agents in the reconfigurable network topology, and determining an action based upon a received control message and the determined local topology.Type: GrantFiled: May 22, 2002Date of Patent: October 21, 2003Assignee: University of Southern CaliforniaInventors: Wei-Min Shen, Behnam Salemi, Peter Will
