Change-Robust Online Topological Memory for Long-Term Relocalization and Semantic Navigation
Jiaming Wang, Jizhuo Chen, Diwen Liu +4
Long-term semantic navigation requires a robot to reuse past observations after appearance and scene change, but semantic memories are only useful if the robot can relocalize into…
GBPP: Grasp-Aware Base Placement Prediction for Robots via Two-Stage Learning
Jizhuo Chen, Diwen Liu, Jiaming Wang +1
GBPP is a fast learning based scorer that selects a robot base pose for grasping from a single RGB-D snapshot. The method uses a two stage curriculum: (1) a simple distance-visibil…
GeNIE: A Generalizable Navigation System for In-the-Wild Environments
Jiaming Wang, Diwen Liu, Jizhuo Chen +4
Reliable navigation in unstructured, real-world environments remains a significant challenge for embodied agents, especially when operating across diverse terrains, weather conditi…
Training-free Task-oriented Grasp Generation
Jiaming Wang, Diwen Liu, Jizhuo Chen +1
This paper presents a training-free pipeline for task-oriented grasp generation that combines pre-trained grasp generation models with vision-language models (VLMs). Unlike traditi…
