In this work, we propose Efficient Collision-Aware Hierarchical Diffusion Navigation (ECAHD), a hierarchical diffusion-based framework designed for both safety and computational efficiency. ECAHD generates a sparse trajectory for global path planning and a dense trajectory for local path refinement.…
Articulation modeling enables robots to learn joint parameters of articulated objects for effective manipulation which can then be used downstream for skill learning or planning. Existing approaches often rely on prior knowledge about the objects, such as the number or type of joints. Some of these …
Teaching robots desired skills in real-world environments remains challenging, especially for non-experts. Current robot learning methods often require expert demonstrations or complex programming, limiting their accessibility to non-experts. We posit that natural language offers an intuitive and ac…
In this paper, we propose a novel method for plane clustering specialized in cluttered scenes using an RGB-D camera and validate its effectiveness through robot grasping experiments. Unlike existing methods, which focus on large- scale indoor structures, our approach—Multi-Object RANSAC emphasizes c…
