  • Patent number: 11450064
    Abstract: A system and method to generate perceptual models of the environment that optimally handle the variation in clutter and provide a multiresolution and multi-fidelity representation of the environment is described. The system and method is able to capture inherent structural dependencies, thereby allowing efficient and precise inferences to be drawn. The approach employs a hierarchy of Gaussian Mixtures to approximate the underlying spatial distribution.
    Type: Grant

  • Patent number: 11310417
    Abstract: A vision-based state estimation framework to estimate the state of an underwater remotely operated vehicle (ROV) used for inspection of an underwater structure, for example, a nuclear reactor pressure vessel. The framework employs an external overhead, pan-tilt-zoom (PTZ) camera as the primary sensing modality and incorporates prior knowledge of the geometry of the structure.

  • Patent number: 11281208
    Abstract: Described herein is a framework for efficient task-agnostic, user-independent adaptive teleoperation of mobile robots and remotely operated vehicles (ROV), including ground vehicles (including legged systems), aircraft, watercraft and spacecraft. The efficiency of a human operator is improved by minimizing the entropy of the control inputs, thereby minimizing operator energy and achieving higher performance in the form of smoother trajectories by concurrently estimating the user intent online and adaptively updating the action set available to the human operator.

  • Publication number: 20170212529
    Abstract: The subject matter described herein includes a modular and extensible approach to integrate noisy measurements from multiple heterogeneous sensors that yield either absolute or relative observations at different and varying time intervals, and to provide smooth and globally consistent estimates of position in real time for autonomous flight. We describe the development of the algorithms and software architecture for a new 1.9 kg MAV platform equipped with an IMU, laser scanner, stereo cameras, pressure altimeter, magnetometer, and a GPS receiver, in which the state estimation and control are performed onboard on an Intel NUC 3rd generation i3 processor. We illustrate the robustness of our framework in large-scale, indoor-outdoor autonomous aerial navigation experiments involving traversals of over 440 meters at average speeds of 1.5 m/s with winds around 10 mph while entering and exiting buildings.
