Enhancing Feature Tracking Reliability for Visual Navigation Using Real-Time Safety Filter

ICRA 2025

Vision sensors are extensively used for localizing a robot's pose, particularly in environments where global localization tools such as GPS or motion capture systems are unavailable. In many visual navigation systems, localization is achieved by detecting and tracking visual features or landmarks, w

Autonomous aerial perching and unperching using omnidirectional tiltrotor and switching controller

ICRA 2024poster

Aerial unperching of multirotors has received little attention as opposed to perching that has been investigated to elongate operation time. This study presents a new aerial robot capable of both perching and unperching autonomously on/from a ferromagnetic surface during flight, and a switching cont…

Safe Receding Horizon Motion Planning with Infinitesimal Update Interval

ICRA 2024poster

Safety verification in motion planning is known to be computationally burdensome, despite its importance in robotics. In this paper, we investigate the behavior of safe receding horizon motion planners when the update interval becomes infinitesimal. By requiring the trajectory parameters to evolve c…

Minimally Actuated Tiltrotor for Perching and Normal Force Exertion

IROS 2023poster

This study presents a new hardware design and control of a minimally actuated 5 control degrees of freedom (CDoF) quadrotor-based tiltrotor. The proposed tiltrotor possesses several characteristics distinct from those found in existing works, including: 1) minimal number of actuators for 5 CDoF, 2)…

Development of a Novel 2-Dimensional Neck Haptic Device for Gait Balance Training

RA-L 2022

Balance problems can be a major cause of falling. Existing gait balance rehabilitation devices usually have limited overground usability due to low portability. Therefore, there is need for development of a portable gait balance rehabilitation system. To fulfill this need, a wearable balance biofeed
