When I started learning robotics, I was lost in terms like stiffness, damping, and feedback control. These slides on the overview of robot control can help you understand what they really mean #Robotics yuxng.github.io/Courses/CS6341…

DINOv3 seems very good at matching objects across environments as well

Introducing DINOv3: a state-of-the-art computer vision model trained with self-supervised learning (SSL) that produces powerful, high-resolution image features. For the first time, a single frozen vision backbone outperforms specialized solutions on multiple long-standing dense

If you don't understand homogeneous transformation matrices, you won't understand robotics🤖. These slides will help you get it yuxng.github.io/Courses/CS6341…

Occlusion is still a challenge for SAM2. Video object segmentation is not solved yet

Are you interested in Vision-Language-Action (VLA) models? We had an excellent guest lecture today by Ankit Goyal @imankitgoyal from NVIDIA on VLAs and their role in robot manipulation 🎥 Watch the recording here 👇 youtube.com/watch?v=IeNwXw… Slides: yuxng.github.io/Courses/CS6341…

The trend in robot manipulation is to collect data and learn end-to-end policies. Do we still need perception or state estimation? My analogy is how Tesla and Waymo are building self-driving cars. The car can understand the 3D world around it. Robots need to have this capability

We can replay the HO-Cap data in #IsaacSim No physics enabled. It is setting the poses of hands and objects according to our annotations

This is a big claim by saying "handle/generalize to any household item". It also highlights that we need some benchmarks for robotics. Unlike all the LLMs that are evaluated and compared on benchmarks, robotics is simply showing demos without numbers

Great efforts on data collection! But I don’t think we’ve figured out how to use these data for robot manipulation yet

today, we’re open sourcing the largest egocentric dataset in history. - 10,000 hours - 2,153 factory workers - 1,080,000,000 frames the era of data scaling in robotics is here. (thread)

This deserves more attention! A real-world benchmark with 30 tasks across 4 robotic platforms, designed to evaluate VLA models. Each task includes 1,000 demos for finetuning. VLAs still have a long way to go. 🤖📊

A general research tip: pay attention to the details. When something strange happens—don’t ignore it. Especially in robotics, odd or incorrect robot behavior often reveals deeper insights. Dig in and ask why
