Escaping Local Minima: Hybrid Artificial Potential Field with Wall-Follower for Decentralized Multi-Robot Navigation

ICRA 2025

We tackle the challenges of decentralized multi-robot navigation in environments with nonconvex obstacles, where complete environmental knowledge is unavailable. While reactive methods like Artificial Potential Field (APF) offer simplicity and efficiency, they suffer from local minima, causing robot

KR-Net: A Dependable Visual Kidnap Recovery Network for Indoor Spaces

IROS 2020poster

In this paper, we propose a dependable visual kidnap recovery (KR) framework that pinpoints a unique pose in a given 3D map when a device is turned on. For this framework, we first develop indoor-GeM (i-GeM), which is an extension of GeM [1] but considerably more robust than other global descriptors…

Automatic Spatial Template Generation for Realistic 3D Modeling of Large-Scale Indoor Spaces

IROS 2019poster

This paper proposes a realistic indoor modeling framework for large-scale indoor spaces. The proposed framework reduces the geometric complexity of an indoor model to efficiently represent large-scale environments for image-based rendering (IBR) approaches. For this purpose, the proposed framework r…

Accurate Continuous Sweeping Framework in Indoor Spaces With Backpack Sensor System for Applications to 3-D Mapping

RA-L 2016

In indoor environments, there exists a few distinctive indoor spaces' features (ISFs). However, up to our knowledge, there is no algorithm that fully utilizes ISF for accurate 3-D SLAM. In this letter, we suggest a sensor system that efficiently captures ISF and propose an algorithm framework that a

3D pose estimation with one plane correspondence using kinect and IMU

IROS 2015poster

In indoor spaces, plane features are general geometric primitives that are robust to noise. To estimate the relative displacement and orientation between two consecutive 3D poses, at least three-pair correspondences of planes with different normals are needed at both poses. Otherwise, the estimated…
