Sphere-VIO: Fast and Robust Visual-Inertial Odometry via Unified Spherical Representation for Heterogeneous Multi-Camera Systems
Yueteng Yang, Yusen Xie, Hao Wei +5
Multi-camera visual-inertial odometry (VIO) overcomes the inherent limitations of pure visual systems by expanding the field of view. However, existing algorithms are typically tai…
LAGO Policy: Latency-Aware Asynchronous Diffusion Policies with Goal-Directed Collision-Free Planning for Smooth Manipulation
Guowei Shi, Xupeng Xie, Yiming Luo +3
Diffusion-based visuomotor policies deployed with asynchronous inference often exhibit inter-chunk discontinuities and lack explicit mechanisms for obstacle-aware execution, leadin…
Palm-sized Omnidirectional Vision-Based UAV Exploration with Sparse Topological Map Guidance
Zirui Wang, Xinjia Luo, Haotian Sun +3
Classic exploration methods often rely on dense occupancy maps or high-resolution point clouds for frontier detection and path planning, resulting in substantial memory consumption…
GUIDE: A Diffusion-Based Autonomous Robot Exploration Framework Using Global Graph Inference
Zijun Che, Yinghong Zhang, Shengyi Liang +3
Autonomous exploration in structured and complex indoor environments remains a challenging task, as existing methods often struggle to appropriately model unobserved space and plan…
AirHunt: Bridging VLM Semantics and Continuous Planning for Efficient Aerial Object Navigation
Xuecheng Chen, Zongzhuo Liu, Jianfa Ma +4
Recent advances in large Vision-Language Models (VLMs) have provided rich semantic understanding that empowers drones to search for open-set objects via natural language instructio…
ApexNav: An Adaptive Exploration Strategy for Zero-Shot Object Navigation with Target-centric Semantic Fusion
Mingjie Zhang, Yuheng Du, Chengkai Wu +4
Navigating unknown environments to find a target object is a significant challenge. While semantic information is crucial for navigation, relying solely on it for decision-making m…
