Grasp, See and Place: Efficient Unknown Object Rearrangement with Policy Structure Prior

1 code implementation23 Feb 2024 Kechun Xu, Zhongxiang Zhou, Jun Wu, Haojian Lu, Rong Xiong, Yue Wang

For the inner loop, we learn an active seeing policy for self-confident object matching to improve the perception of place.

Object-centric Inference for Language Conditioned Placement: A Foundation Model based Approach

no code implementations6 Apr 2023 Zhixuan Xu, Kechun Xu, Yue Wang, Rong Xiong

We focus on the task of language-conditioned object placement, in which a robot should generate placements that satisfy all the spatial relational constraints in language instructions.

Learning A Simulation-based Visual Policy for Real-world Peg In Unseen Holes

1 code implementation9 May 2022 Liang Xie, Hongxiang Yu, Kechun Xu, Tong Yang, Minhang Wang, Haojian Lu, Rong Xiong, Yue Wang

This paper proposes a learning-based visual peg-in-hole that enables training with several shapes in simulation, and adapting to arbitrary unseen shapes in real world with minimal sim-to-real cost.

Efficient learning of goal-oriented push-grasping synergy in clutter

1 code implementation9 Mar 2021 Kechun Xu, Hongxiang Yu, Qianen Lai, Yue Wang, Rong Xiong

In this paper, a goal-conditioned hierarchical reinforcement learning formulation with high sample efficiency is proposed to learn a push-grasping policy for grasping a specific object in clutter.
