This paper presents an approach for the localization of an Unmanned Underwater Vehicle (UUV) in a cooperative team with a tethered Unmanned Surface Vehicle (USV). For the localization, the UUV and the USV carry a camera and a sonar respectively to observe each other. The vehicle states are split bet
This paper presents a novel strategy for offline estimation of the spatial motion of a multi-link mechanism using Inertial Measurement Unit (IMU) sensors. Accelerometers, gyroscopes and magnetometers are strategically mounted and modeled to maximize measurement accuracy through the past work of iner
Inertial sensing estimation methods allows human motion tracking in the absence of optical tracking and joint encoders, but the methods are rather developed for quasistatic motion due to the limited motion capability of humanoids. This paper presents a new method that tracks highly dynamic motion us
This paper presents a data-driven multiple model framework for estimating the intention of a target from observations. Multiple model (MM) state estimation methods have been extensively used for intention estimation by mapping one intention to one dynamic model assuming one-to-one relations. However…
Autonomous robots need to recognize the environment by identifying the scene. Scan context is one of global descriptors, and it encodes the three-dimensional scan data of the scene for the identification in a matrix form. Scan context is in a matrix form that is simple to store, but the matching of…
This paper presents a technique that allows a robot to escort a human to their destination. Unlike tracking where the robot follows the human from behind, the proposed technique locates the robot in front of the human by incorporating human intention in addition to conventional motion prediction. Hu…
This paper presents a technique for state estimation of a multi-link system having no joint encoders, which can only be partially observed by a camera. To fully observe the system without changing the current configuration, a gyroscope and an accelerometer are attached to each link as dead-reckoning…
This paper proposes a belief-driven control policy of a drone with microphones for multiple sound source search. As the sound source localization by drones is uncertain because of the observation significantly distorted by noise such as rotor noise, the belief on the estimated targets may consist of…
This paper presents a vision-based technique and a system developed for the global reconstruction of three-dimensional (3-D) road surfaces. Using the system, the technique globally reconstructs 3-D road surfaces by estimating the global camera pose using the Adaptive Extended Kalman Filter (AEKF) an…
This paper proposes a probabilistic framework for classification of evolving targets, leveraging the principles of recursive Bayesian estimation in a perception-oriented context. By implementing a Gaussian toroid prediction model of the perception target's evolution, the proposed recursive Bayesian…
This paper presents a framework for engaging a target while approaching it from a long distance, using observation from sensors on-board a mobile robot. The proposed framework consists of two multi-stage Bayesian approaches to reliably detect and accurately engage with the target under uncertainties…
This paper presents an algorithm for localizing an unmanned aerial vehicle (UAV) in GPS denied environments. Localization is performed with respect to a pre-built map of the environment represented using the distance function of a binary mosaic, avoiding the need for extraction and explicit matching…
This paper presents a generalized multi-stage Bayesian approach for an unmanned aerial vehicle to estimate the location of a mobile target. The major hardware components of the proposed approach are a camera with a fisheye lens and another camera with a normal lens and a pan/tilt unit. With wide ang…
This paper describes a non-field-of-view (NFOV) localization approach for a mobile robot in an unknown environment based on an acoustic signal combined with the geometrical information from an optical sensor. The approach estimates the location of a target through the mobile robot's sensor observati…
