Works like this deserve a lot more attention. In embodied AI, the most common argument against physics-based simulation is that deformables are hard/expensive to simulate. Offset Geometric Contact just made it 300x faster. It computes vertex-specific displacement bounds toโฆ

Implementing motion imitation methods involves lots of nuisances. Not many codebases get all the details right. So, we're excited to release MimicKit! github.com/xbpeng/MimicKit A framework with high quality implementations of our methods: DeepMimic, AMP, ASE, ADD, and more to come!
Very clean and applied work. The next 3 years are going to be crazy for humanoid demos.

I'm super excited to announce mjlab today! mjlab = Isaac Lab's APIs + best-in-class MuJoCo physics + massively parallel GPU acceleration Built directly on MuJoCo Warp with the abstractions you love.
Funny. HTX in Chinese tech community is seen as one having bad tech skills but strong media skills to become a tech influential. If you call any professional technician "you are like HTX" it's kinda an offense. But this won't deny HTX from the popularity for common audience.
Hangzhou is insane. Just look at what these kids do. They casually made a fleet of trash-catching trash cans for a 3 minute video. 232 likes as of now. And all their stuff is like this.
Very honoured to have our work on generalized legged locomotion published in Science Robotics @SciRobotics ! (with @JayHe748646 @leggedrobotics ) (I show up on the left of screenshot here) Here is a thread of takeaways and some personal opinions.
It seems like there is not enough of a policy response to the fact that, with 57M miles of data, Waymoโs autonomous vehicles experience 85% less serious injuries & 79% less injuries overall than cars with human drivers. 2.4 million are injured & 40k killed in US accidents a year
The cool Boston Dynamics results from yesterday are based on Toyota large behavior models, which are not large pretrained VLM foundation models. In the end the bottleneck for robotics is... robotics. Good data good hardware etc. Don't be disempowered.
"As roboticists and computer vision people [outside of big tech], do we just wait for the next foundation model?" I share the frustration. It's disempowering when most major progress recently is downstream of "foundation models" that you don't have the compute or data to train.
AgiBot (Zhiyuan Innovation) has launched sales of its full humanoid robot product lineup officially on its e-commerce website and on JD'.com. Lingxi X2: 27 DoF, 131 cm (4'3") height, 35 kg (77 lb) weight. 'Youth Edition' priced at ยฅ98,000 ($13.6k).
Unitree wins the gold medal for the 1500m run at the World Humanoid Robot Games, setting a world record time of 6 minutes and 34 seconds. The current men's world record is 3:26.
Want to achieve extreme performance in motion trackingโand go beyond it? Our preprint tech report is now online, with open-source code available!

What a vibe
Wheeled humanoid robot is also humanoid robot
Getting up is nothing fancy nowadays but it still feels great to have it.
They say the best time to tweet about your research was 1 year ago, the second best time is now. With RAI formerly known as Boston Dynamics AI Institute, we present DiffuseCloC - the first guidable physics-based diffusion model. diffusecloc.github.io/website/
