OREN: Octree Residual Network for Real-Time Euclidean Signed Distance Mapping
Zhirui Dai, Qihao Qian, Tianxing Fan +1
Reconstructing signed distance functions (SDFs) from point cloud data benefits many robot autonomy capabilities, including localization, mapping, motion planning, and control. Meth…
Seeing the Bigger Picture: 3D Latent Mapping for Mobile Manipulation Policy Learning
Sunghwan Kim, Woojeh Chung, Zhirui Dai +5
In this paper, we demonstrate that mobile manipulation policies utilizing a 3D latent map achieve stronger spatial and temporal reasoning than policies relying solely on images. We…
Learning Scene-Level Signed Directional Distance Function with Ellipsoidal Priors and Neural Residuals
Zhirui Dai, Hojoon Shin, Yulun Tian +2
Dense reconstruction and differentiable rendering are fundamental tightly connected operations in 3D vision and computer graphics. Recent neural implicit representations demonstrat…
LTLCodeGen: Code Generation of Syntactically Correct Temporal Logic for Robot Task Planning
Behrad Rabiei, Mahesh Kumar A. R., Zhirui Dai +3
This paper focuses on planning robot navigation tasks from natural language specifications. We develop a modular approach, where a large language model (LLM) translates the natural…
