@notprajyoth The material estimation module was trained under a synthetic dataset augmented from a baseline dataset, where the material properties are randomized for each synthetic demo. It was then tested on unseen real-world demos (shown in the video) and the dynamics correction works well.
Excited to share our #CoRL2026 work PhysCoRe: a physics-corrected world model for deformable objects!
We couple a physics-based simulator with two feed-forward modules: one infers material from vision, the other corrects its internal dynamics.

Thrilled to share our latest research work on generative predictive control (GPC)! It’s been an incredible journey working on this project with @hanqi359246, Prof. Yilun @du_yilun and Prof. Hank @hankyang94 at Harvard SEAS! Really grateful for their supervision and collaboration!
Diffusion has shown great promise for generating robot **actions**, can it act as a **world model** to generate the future conditioned on actions?
In our work led by @hanqi359246@hcy1n and in collaboration with @du_yilun, we show a **controllable** action-conditioned video diffusion model can produce photorealistic and (near) physics-accurate future predictions.
This ability strengthens the policy via:
- ranking different action proposals and selecting the best, or
- **visual** trajectory optimization by optimizing the action proposals using gradient ascent.

Robots in our group are finally moving!
Excited to share the first #RobotLearning project from my group led by Han Qi and @hcy1n:
Control-oriented Clustering of Visual Latent Representation
In classical robotics, "perception" and "control" are separated with an explicit state representation.
In end-to-end vision-based control, what's going on in the visual latent representation space?
- Focusing on the planar pushing task, we found an elegant geometric structure in the visual latent space: visual features are clustered according to "control-oriented" goals. Moreover, such clustering has a rigid structure known as "neural collapse" (NC, first found in the image classification literature).
- How does this understanding help? We show that pretraining the vision encoder with control-oriented clustering significantly increases test-time performance in the low-data regime (e.g., 50 or 100 demos). For example, with 100 demos, baseline succeeds 5 out of 10, but NC-pretrained policy succeeds 8 out of 10.
