PoCo: Policy Composition from and for Heterogeneous Robot Learning

no code implementations4 Feb 2024 Lirui Wang, Jialiang Zhao, Yilun Du, Edward H. Adelson, Russ Tedrake

Training general robotic policies from heterogeneous data for different tasks is a significant challenge.

GenSim: Generating Robotic Simulation Tasks via Large Language Models

1 code implementation2 Oct 2023 Lirui Wang, Yiyang Ling, Zhecheng Yuan, Mohit Shridhar, Chen Bao, Yuzhe Qin, Bailin Wang, Huazhe Xu, Xiaolong Wang

Collecting large amounts of real-world interaction data to train general robotic policies is often prohibitively expensive, thus motivating the use of simulation data.

Robot Fleet Learning via Policy Merging

1 code implementation2 Oct 2023 Lirui Wang, Kaiqing Zhang, Allan Zhou, Max Simchowitz, Russ Tedrake

We show that FLEET-MERGE consolidates the behavior of policies trained on 50 tasks in the Meta-World environment, with good performance on nearly all training tasks at test time.

NeRF in the Palm of Your Hand: Corrective Augmentation for Robotics via Novel-View Synthesis

no code implementations CVPR 2023 Allan Zhou, Moo Jin Kim, Lirui Wang, Pete Florence, Chelsea Finn

Expert demonstrations are a rich source of supervision for training visual robotic manipulation policies, but imitation learning methods often require either a large number of demonstrations or expensive online expert supervision to learn reactive closed-loop behaviors.

Does Learning from Decentralized Non-IID Unlabeled Data Benefit from Self Supervision?

1 code implementation20 Oct 2022 Lirui Wang, Kaiqing Zhang, Yunzhu Li, Yonglong Tian, Russ Tedrake

Decentralized learning has been advocated and widely deployed to make efficient use of distributed datasets, with an extensive focus on supervised learning (SL) problems.

Goal-Auxiliary Actor-Critic for 6D Robotic Grasping with Point Clouds

1 code implementation2 Oct 2020 Lirui Wang, Yu Xiang, Wei Yang, Arsalan Mousavian, Dieter Fox

We demonstrate that our learned policy can be integrated into a tabletop 6D grasping system and a human-robot handover system to improve the grasping performance of unseen objects.

Manipulation Trajectory Optimization with Online Grasp Synthesis and Selection

1 code implementation22 Nov 2019 Lirui Wang, Yu Xiang, Dieter Fox

In robot manipulation, planning the motion of a robot manipulator to grasp an object is a fundamental problem.
