Beyond Imitation: Robots Learn to Adapt with Generative Policies

November 16, 2025 by BBG News

UEPO leverages a multi-seed diffusion sampling strategy to initialize a policy, subsequently enhancing diversity during offline optimization through a regularization mechanism that maximizes policy divergence, all while concurrently training a dynamics model $T^\hat{T}$ with both real and synthetic data to bolster generalization before selecting a qualifying policy for online fine-tuning.

A new framework leverages the power of diffusion models to create diverse and robust policies, bridging the gap between offline data and real-world robot performance.

Decoding Protein Motion with Digital Building Blocks

November 15, 2025 by BBG News

Protein structures are discretized into a vocabulary of “Structure Tokens” by a Vector Quantized Variational Autoencoder, enabling an autoregressive language model to predict structural sequences conditioned on the underlying amino acid sequence, thereby framing protein structure prediction as a discrete sequence modeling problem.

A new approach leverages discrete representations of protein structure to efficiently generate diverse and realistic conformational ensembles, offering a fresh perspective on modeling protein dynamics.

PuffyBot: A Robot That Walks, Swims, and Floats

November 15, 2025 by BBG News

The robot transitions seamlessly between underwater states—from resting on the seabed at $0$ seconds, to initiating body expansion and lift-off by $5$ seconds, achieving positive buoyancy and ascent at $45$ seconds, and finally surfacing completely at $46$ seconds—demonstrating shape-morphing driven buoyancy control.

Researchers have developed an untethered, shape-morphing robot capable of seamlessly transitioning between land, underwater, and surface locomotion with improved energy efficiency.
