Heads up‼️ RI seminars are back underway for the spring semester! 🌷🤖
You can find the latest recorded talks from Andrea Bajcsy and Aaron Johnson on the CMU RI YouTube channel. Keep an eye out for more! ⬇️ #CMURobotics

It has pretty much the same features as ChatGPT and it feels good to support 🇪🇺
We need a diversity of solutions to accelerate innovation!
"Our study reveals [...] increased model accuracy only marginally improves sample efficiency compared to learned models with identical horizons"
Surely an involved read from @tuda.bsky.social & @hessianai.bsky.social, but recommended if you are into model-based RL.
Also, ✨nice figures✨

For other 3D vision newcomers to blue sky: I highly recommend joning @chrisoffner3d.bsky.social 's list to follow the right people ;): go.bsky.app/Cfm9XFe
🎊 Happy new year robotics community !
Best wishes for the growing robotics community 🥂
Paper curation will resume tomorrow, but user lists and the starter pack are continuously updated.
Most notably, Pr. (@yiannisdemiris.bsky.social) from Imperial College joined us recently and has been added !
Release of open source software (inc #ROS packages) to control the Boston Dynamics Spot with #Hololens #AR glasses. Work by Dr Rodrigo Chacon at the Personal #Robotics Lab at Imperial College London. Papers with extensive user evaluations, code and more videos at github.com/ImperialColl...
Inspired by @wimlds.bsky.social , I looked for a "Women in Machine Learning" starter pack and couldn't find one.
So I created one! May have some mistakes. I'll try to do an AI ethics one next. 🤗

If you're training models with more than one loss term, I can again strongly recommend our ConFIG optimizer: tum-pbs.github.io/ConFIG/ , simply swap out Adam&Co. for ConFIG, and you can potentially see substantial reductions in your training loss 😁 We'd also be curious to hear how it works for you
A fresh approach to optimal control leveraging ideas from cognitive science.
With only 10 pages it is a recommended read for its original approach and the potential in further developments.

We now have a starter pack for ROBOTICS. This should be a fun group.
Are you building robots or sharing thoughts/research on the state of robotics? 🤖🦿
Request to join if you would like to be added, before it fills up.

Hi, I’d love to be added if you don’t mind !
The first is full but still incomplete. Here is the second one, also largely incomplete. Just say 👋 and you will be added.

We’ve been investigating how sim, while wrong, can be useful for real-world robotic RL! In our #NeurIPS2024 work, we theoretically showed how naive sim2real transfer can be inefficient, but if you *learn to explore* in sim, this transfers to the real world! We show this works on real robots! 🧵(1/6)
Point cloud segmentation is a crucial challenge in robotics, which this paper tackles without deep learning but by introducing a new member to the ever-growing families of positional embeddings.
While confusing at times, it is an interesting read if you are into machine learning for geometric tasks
🤖 "Robot" usually evokes a #quadruped or #humanoid system. However, they can also be... liquid ferrofluid marbles.
📄 This 100% 'machine learning' free paper is a sobering return to physics and reminds us that #robotics is, before all, the art of controlling motion.

Today we get two (don't get used to it) little gems from Iran to remind us all that robotics is not all deep and reinforcement learning !

I'm excited about scaling up robot learning! We’ve been scaling up data gen with RL in realistic sims generated from crowdsourced videos. Enables data collection far more cheaply than real world teleop. Importantly, data becomes *cheaper* with more environments and transfers to real robots! 🧵 (1/N)
From Instantaneous to Predictive Control: A More Intuitive and Tunable MPC Formulation for Robot Manipulators

Check out my #robotics lists and please RT to reach people I might have missed.

Starter pack will be updated to mirror Robotics & ML posting
In my continued effort to give visibility to researchers and lower the entry bar for robotics enthusiasts on 🦋, I have found that lists are a great tools to order content.
Lists can be pinned to the home screen, effectively acting as curated feeds.
With 20 spaces left in the #ResearchIntegrity Starter Pack, could we fill these with early career researchers/professionals or others who might not feel confident putting themselves on the list?
If you have suggestions for people who'd be a good fit, please let me know!

I made an HRI Starter Pack!
If you are a Human-Robot Interaction or Social Robotics researcher and I missed you while scrolling through bsky's suggestions, just ping me and I'll add ya.

Done !
