GOTPR: General Outdoor Text-based Place Recognition Using Scene Graph Retrieval with OpenStreetMap
Donghwi Jung, Keonwoo Kim, Seong-Woo Kim
We propose GOTPR, a robust place recognition method designed for outdoor environments where GPS signals are unavailable. Unlike existing approaches that use point cloud maps, which…
Point Cloud Structural Similarity-based Underwater Sonar Loop Detection
Donghwi Jung, Andres Pulido, Jane Shin +1
In this letter, we propose a point cloud structural similarity-based loop detection method for underwater Simultaneous Localization and Mapping using sonar sensors. Existing sonar-…
E2Map: Experience-and-Emotion Map for Self-Reflective Robot Navigation with Language Models
Chan Kim, Keonwoo Kim, Mintaek Oh +10
Large language models (LLMs) have shown significant potential in guiding embodied agents to execute language instructions across a range of tasks, including robotic manipulation an…
No More Potentially Dynamic Objects: Static Point Cloud Map Generation based on 3D Object Detection and Ground Projection
Soojin Woo, Donghwi Jung, Seong-Woo Kim
In this paper, we propose an algorithm to generate a static point cloud map based on LiDAR point cloud data. Our proposed pipeline detects dynamic objects using 3D object detectors…
3D Operation of Autonomous Excavator based on Reinforcement Learning through Independent Reward for Individual Joints
Yoonkyu Yoo, Donghwi Jung, Seong-Woo Kim
In this paper, we propose a control algorithm based on reinforcement learning, employing independent rewards for each joint to control excavators in a 3D space. The aim of this res…
MuNES: Multifloor Navigation Including Elevators and Stairs
Donghwi Jung, Chan Kim, Jae-Kyung Cho +1
We propose a scheme called MuNES for single mapping and trajectory planning including elevators and stairs. Optimized multifloor trajectories are important for optimal interfloor m…
LoRCoN-LO: Long-term Recurrent Convolutional Network-based LiDAR Odometry
Donghwi Jung, Jae-Kyung Cho, Younghwa Jung +2
We propose a deep learning-based LiDAR odometry estimation method called LoRCoN-LO that utilizes the long-term recurrent convolutional network (LRCN) structure. The LRCN layer is a…
A Robotic Dating Coaching System Leveraging Online Communities Posts
Sihyeon Jo, Donghwi Jung, Keonwoo Kim +6
Can a robot be a personal dating coach? Even with the increasing amount of conversational data on the internet, the implementation of conversational robots remains a challenge. In…
