Bearing-Only Navigation with Field of View Constraints [PDF]
IEEE Control Systems Letters, 2020 This paper addresses the problem of navigation using only relative direction measurements (i.e., relative distances are unknown) under field of view constraints. We present a novel navigation vector field for the bearing-based visual homing problem with respect to static visual landmarks in 2-D and 3-D environments.

Hybrid Guidance Optimization for Multipulse Glideslope Approach with Bearing-Only Navigation [PDF]
Aerospace, 2022 This paper proposes a modified glideslope guidance method that optimizes a hybrid multiobjective of bearing-only navigation error and fuel consumption. The traditional glideslope guidance fixes uniform maneuver intervals and the initial approach velocity

Sample-Based Output-Feedback Navigation with Bearing Measurements [PDF]
arXiv, 2022 We consider the problem of sample-based feedback-based motion planning from bearing (direction-only) measurements. We build on our previous work that defines a cell decomposition of the environment using RRT*, and finds an output feedback controller to navigate through each cell toward a goal location using duality, Control Lyapunov and Barrier ...

Integration of Hardware and Software Designs for Object Grasping and Transportation by A Mobile Robot With Navigation Guidance via a Unique and Elegant Design of Bearing Alignment Mechanism [PDF]
IEEE/ASME transactions on mechatronics, 2015 In this paper, we consider the systematic design and implementation of grasping and transportation by a mobile robot with low implementation complexity. The study is mainly divided into three aspects: 1) design of a mechanical gripper and an arm mounted ...

Autonomous Underwater Vehicle Navigation via Sensors Maximum-Ratio Combining in Absence of Bearing Angle Data [PDF]
Journal of Marine Science and Engineering, 2023 This paper proposes a maximum-ratio combining sensor fusion scheme for using an extended Kalman filter in the underwater vehicle positioning task by means of communication devices (buoys) providing location information using a slant-range mechanism ...

Optimal Trajectories for Homing Navigation with Bearing Measurements
IFAC Proceedings Volumes, 2008 In this paper we examine the geometry of a number of navigation schemes for guiding a pursuer from a fixed initial position to a final target position. We explicitly characterize the optimal pursuer trajectories for the given problems in terms of minimizing the error in an unbiased estimate of the target position from successive bearing measurements ...

Visibility-Inspired Models of Touch Sensors for Navigation [PDF]
IEEE/RJS International Conference on Intelligent RObots and Systems, 2022 This paper introduces mathematical models of \sensors\ for mobile robots based on visibility. Serving a purpose similar to the pinhole camera model for computer vision, the introduced models are expected to provide a useful, idealized characterization of task-relevant information that can be inferred from their outputs or observations.
