Robots copy walking styles from motion examples

Disney Research and ETH Zurich demonstrated a locomotion system that takes a movement-style example and a joystick velocity command as separate inputs. A style encoder conditions an autoregressive diffusion model, which generates reference motions for a reinforcement-learning controller to follow.

The team demonstrated real-time control and continuous style changes in a simulated humanoid and on a physical robot. The method learns from unstructured motion recordings without explicit style labels and can reproduce styles not seen during training.

AI predicts how metal melts during laser welding in milliseconds

Empa and Terra Quantum developed a machine-learning model that predicts three-dimensional temperature fields and melt-pool boundaries in laser welding. After training, the Laser Processing Fourier Neural Operator produced predictions in about eight milliseconds at standard resolution and 88 milliseconds at twice that resolution, replacing physics simulations that took minutes or more than an hour.

The model learns how laser power and scanning speed affect the heated metal. Its formulation follows the moving laser and averages over time, making it useful for stable welding conditions. Strongly transient effects, including pore formation and collapsing vapour cavities, remain unresolved; real-time factory control is a prospective application rather than a demonstrated deployment.

FLUX-mimic learns to sort car parts

Mimic and BMW researchers tested FLUX-mimic on automotive tasks including component assembly, cable routing and sorting deformable foam parts into trays. The model combines a pretrained FLUX 3 video backbone with an action model that generates robot movements, without needing to generate a complete video during operation.

In the foam-part sorting experiment, a Franka robot succeeded in 95% of 40 trials after eight hours of action-labelled demonstrations. That figure excludes earlier backbone pretraining: the project collected nearly 296 hours of industrial recordings across 31 tasks, alongside the backbone's broader training data. The results demonstrate controlled research tasks with separately trained robot policies, not general-purpose factory autonomy.

Open-source GENCO model speeds up power-grid calculations

IBM Research and collaborators including ETH Zurich have released GENCO, an open neural solver that handles power flow, generator optimisation and state estimation in one model. The team evaluated it using a full year of operational measurements from Hydro-Quebec's 1,200-node transmission network, alongside benchmark grids with up to 10,000 nodes.

The reported benchmarks show up to 30-fold faster power-flow calculations and up to 85-fold faster optimisation than the classical solvers used for comparison. The release includes training tools, models and datasets through OpenGridFM. GENCO is intended to screen large numbers of scenarios alongside established numerical solvers, which still provide authoritative answers for critical cases.

AI evaluates race-car aerodynamics in seconds instead of hours

IBM researchers working with Dallara have demonstrated a machine-learning model that evaluates race-car diffuser designs in about ten seconds, compared with several hours for conventional computational fluid dynamics. In a comparison using an LMP2-like car, both approaches selected the same optimal design. The model learned from Dallara's engineering-validated simulations and was tested on held-out examples.

The Gauge-Invariant Spectral Transformer, or GIST, uses both mesh coordinates and their connections to represent detailed aerodynamic surfaces. The work includes Cristiano Malossi's team at IBM Research Zurich. These are preliminary simulation results for design screening; performance on unfamiliar vehicles still needs validation. Quantum computing is a proposed future direction, not part of the demonstrated acceleration.

Docling extracts text and tables from PDFs as open-source software

IBM Research Zurich's AI for knowledge team made Docling publicly available as an open-source document conversion toolkit. The first public release, version 0.1.1, appeared on July 15, followed by version 1.0 three days later. The software combines specialised AI models for document layout and table structure with a pipeline that extracts useful information from PDFs.

Released under the permissive MIT licence, Docling was designed to run on ordinary computing hardware and to support extensions with additional models and processing features. Its structured document outputs provide a foundation for search, retrieval-augmented generation and AI training workflows. The pipeline moves beyond extracting isolated text by preserving document organisation and tables, making information in complex reports and other PDFs more accessible to downstream software.

Event cameras and AI speed up obstacle detection

University of Zurich researchers Daniel Gehrig and Davide Scaramuzza developed a hybrid vision system that combines conventional images with the rapid brightness-change signals produced by an event camera. A convolutional neural network processes the ordinary images, while an asynchronous graph neural network analyses events to anticipate objects appearing between frames. The system was presented in a Nature study.

In the reported comparisons, the hybrid detector reduced detection latency by a factor of 100 without sacrificing accuracy. Its conventional camera operated at 20 frames per second; the combined system offered detection timing comparable to a 5,000-frame-per-second camera at the bandwidth of a conventional 50-frame-per-second camera. The research addresses the delay between capturing a scene and detecting an obstacle, a critical perception bottleneck in driver assistance and autonomous vehicles.

64-core analog chip runs neural networks using memory cells

IBM researchers presented a 64-core mixed-signal chip that performs neural-network calculations using phase-change memory. Instead of repeatedly transferring stored weights to a separate arithmetic unit, the chip represents those weights through electrical conductance and carries out matrix operations within memory arrays. The design combines this analog computation with digital functions for processing activations and moving information between cores.

The international team included IBM Research Zurich's Manuel Le Gallo and colleagues working on in-memory computing. Manufactured in a 14-nanometre process, the research chip demonstrated inference on networks including image-recognition and recurrent models with accuracy approaching software implementations. Published in Nature Electronics, the work addressed how analog computing could support more complete neural-network workloads rather than isolated operations. The research processor brought analog memory arrays and their supporting digital circuitry together on one chip.

FRAN makes faces look older or younger in video

Disney Research Studios and ETH Zurich researchers presented FRAN, a neural method for changing a person's apparent age in video while preserving identity and expression. The system was trained using synthetic images of faces at different ages, addressing the difficulty of assembling real photographs of the same people across decades. Its image-to-image network applies age-related changes while retaining details needed for visual-effects work.

The research focused on consistency across video frames and robustness to variations in viewpoint, lighting and facial expression. It also provided controls for artists to adjust the effect locally rather than accepting a single automatic result for the entire face. Published as production-ready face re-aging research, FRAN gave visual-effects artists a tool for applying consistent age changes while retaining control of the final appearance.

LatticeFlow raises USD 12M Series A

Zurich-based LatticeFlow raised USD 12 million in a Series A backed by Atlantic Bridge, OpenOcean and FPV Ventures, with existing investors also participating. The ETH Zurich spin-off develops tools to identify problems in computer vision datasets and models before those problems undermine real-world deployment. Investor btov, now b2venture, announced the financing on 26 October.

The platform addresses the gap between performance on laboratory datasets and reliability in production, where images and operating conditions can differ from training examples. Its tools automate diagnosis and correction work that otherwise requires machine learning engineers to inspect data and models manually. At the announcement, the company cited customers including Siemens Mobility and AI businesses Intenseye, Voxel AI and Carscan.

ANYmal robot uses vision and touch to navigate rough terrain

ETH Zurich researchers developed a controller that lets the four-legged ANYmal robot combine what its cameras perceive with information about its own movements and contact with the ground. The system learns when visual measurements are unreliable, allowing it to continue across obstacles even when snow, vegetation or poor visibility make the terrain difficult to interpret. Marco Hutter's group trained the controller in simulation before testing it outdoors.

On a route up Mount Etzel, the robot covered 120 metres of elevation in 31 minutes without falling. The result, reported in Science Robotics, addresses a practical limitation of walking robots: neither vision alone nor feedback from the legs is sufficient in every environment. The controller combines both sources rather than requiring an accurate terrain model at every step.
