@TX_Leo_Wang Nice work, Leo!

[Gao Jiawei @WinstonGu_]

@Figure_robot Nice Demo! Multi-robot cooperation is an important task in household activities, and we did some research on this topic in 2023. Everything open-sourced, find out more at https://t.co/v2U356g4g8

[Gao Jiawei @WinstonGu_]

@KBlueleaf Yep, simple and effective!

[Gao Jiawei @WinstonGu_]

Check out our new work on an interesting action tokenizer design! https://t.co/vUKnRhAldr
Chaoqi's insightful post is definitely worth reading.

@jbhuang0604 From the perspective of an PhD applicant, it is hard to apply for a phd position these years given that many faculties are actually on-leave.

[Gao Jiawei @WinstonGu_]

This matches my intuition! Check out this work on scientifically and systematically understanding Flow Policies vs. Regression Policies in Robotics!

[Chaoyi Pan @ChaoyiPan]

Generative models (diffusion/flow) are taking over robotics 🤖. But do we really need to model the full action distribution to control a robot?

We suspected the success of Generative Control Policies (GCPs) might be "Much Ado About Noising."

We rigorously tested the myths. 🧵👇

Just reconstructed a 3D model of Porcelain Tower of Nanjing(南京大報恩寺琉璃塔) using SAM 3D. The tower was burned down in 1856, which means it would in no way exist in the training data.

The result is CRAZY.

@JieWang_ZJUI @physical_int @sundayrobotics @hausman_k This is just espresso, by the way. I’m wondering if the current policies can froth the milk.

@ChaoyiPan Impressive work! Hopefully one day we can retarget robot-spider motions using SPIDER!

[Gao Jiawei @WinstonGu_]

@wandb Wow!

[Gao Jiawei @WinstonGu_]

@siyuanhuang95 Nice work!

[Gao Jiawei @WinstonGu_]

@ChongZitaZhang Bro I have no humanoids on hand right now🤣

[Gao Jiawei @WinstonGu_]

It would be really exciting if someone could build on this work for humanoid robots! Original code at https://t.co/2Oakgq0p53

[Gao Jiawei @WinstonGu_]

Imagine a future where you can ask humanoid robots to clean your room, but some items, like heavy sofas, are too challenging for just one robot to move.

Introducing CooHOI, a learning-based framework designed for the cooperative transportation of objects by multiple humanoid robots. 🤖🤼🤖

Our work has been accepted as Spotlight at NeurIPS 2024. Website: https://t.co/gWFSYEqAAD

@ZeYanjie Truly useful👍

[Gao Jiawei @WinstonGu_]

@BenQingwei Congrats bro, a project full of memories😆

[Gao Jiawei @WinstonGu_]

Learned a lot from this insightful post! Really hope there will be more posts like this in the community.

[Seohong Park @seohong_park]

Q-learning is not yet scalable

https://t.co/hoYUdAAeGZ

I wrote a blog post about my thoughts on scalable RL algorithms.

To be clear, I'm still highly optimistic about off-policy RL and Q-learning! I just think we haven't found the right solution yet (the post discusses why).

@xiaolonw Congratulations!!

@zhengyiluo @kkitani @shubhtuls @GuanyaShi @xbpeng4 Congrats!!

[Gao Jiawei @WinstonGu_]

@_tonytao_ Nice demos😆! Congrats tony!
