Chinese regulators block SoftBank's $5.4 billion acquisition of ABB's robotics business

This week embodied intelligence models were updated intensively; NVIDIA VFlash replaces token-by-token generation with parallel decoding, speeding up robot action decoding by up to 12 times. On the industry side, Chinese regulators blocked SoftBank's $5.375 billion acquisition of ABB's robotics business, and Walmart and Symbotic expanded their agreement with a commitment of about $6 billion in initial investment. On the research side, the focus is on data and simulation, with PrimeSim, HALO, and others using large-scale demonstrations and synthetic data to advance general world models and zero-shot real-robot transfer.

Model Releases/Updates

This week, multiple institutions launched world action models and whole-body control models, covering navigation, mobile manipulation, and dexterous manipulation, with an emphasis on open source and public technical reports.

  • NVIDIA releases VFlash visual planning decoding framework, accelerating robot action decoding by up to 12x

    NVIDIA released VFlash, a general-purpose decoding framework for fast visual planning, which uses parallel decoding of complete visual primitives to replace token-by-token coordinate generation, enabling prediction of robot grasp positions and motion trajectories in one pass. At batch size 1 on H100, single-pass generation speed improves by about 25x, and across four MolmoSpaces tasks the world action model achieves an average success rate of 70.2% versus a baseline of 62.6%. Jim Fan shared that it achieves up to 12x action decoding acceleration, 5.1x overall robot inference acceleration, and up to 61% reduction in 3D trajectory error.

    China's Foreign Investment Security Review Working Mechanism Office prohibited SoftBank's $5.375 billion acquisition of ABB's robotics business, citing reasons involving robot data being transferred overseas and used to train AI models. ABB Robotics' orders from China in fiscal 2025 were $928,000, up from $662,000 in 2024, and its China business grew 32% in the third quarter of 2026, with about 90% of the robots produced at its Shanghai factory for local customers manufactured locally. ABB said it remains in close communication with SoftBank and is advancing the transaction.

  • Leaderdrive's first three quarters revenue up 45%, humanoid reducer orders reach 400,000 units

    Leaderdrive's revenue in the first three quarters of 2026 was 591 million yuan, up 45.30% year on year, with net profit attributable to shareholders of 122 million yuan, up 30.33% year on year, and humanoid-related reducer orders increased from about 100,000 units the previous year to 400,000 units. The company's annual harmonic reducer capacity has reached 1 million units, with a year-end target of 1.5 million units, but first-half gross margin was 32.26%, down 2.51 percentage points year on year, as new production line commissioning and small-batch production of multiple models are weighing on profitability. The article also compares the catch-up pace of domestic manufacturers such as Zhongda Drede, Huandong Technology, and Laifu Harmonic.

  • HALO: a humanoid robot autonomy system trained on synthetic simulation data achieves zero-shot real-robot transfer

    The research team proposed HALO, a humanoid robot autonomy system, which synthesizes vision-language-action data in about one thousand procedurally generated home scenes to eliminate reliance on teleoperation collection. HALO learns skills such as sitting on a chair, navigating to a specified object, turning sideways to pass through a half-open door, crouching and crawling under a table, and pushing a box, and can combine them to complete long-horizon tasks. Without having seen real home scenes during training, HALO transferred zero-shot to the physical world, achieving a 91% success rate across 360 trials in six unmapped real environments.

  • Any3R open-sourced: one model uniformly handles 3D reconstruction and pose estimation for pinhole, fisheye, and panoramic cameras

    South Dakota State University and other institutions proposed Any3R, which describes arbitrary central cameras with a dense ray field and can reconstruct a 3D point cloud and estimate pose from mixed-camera images in a single forward pass. The method replaces the row and column indices of rotary position encoding with angular coordinates and weights pixel loss by solid angle, enabling one set of weights to cover pinhole, over-180° fisheye, and 360° panoramic cameras. On benchmarks across 13 central camera types and 3 datasets, its reconstruction accuracy and pose accuracy both lead, and the inference code, 13 camera models, and weights have been open-sourced.

  • RoboTryOn: Synthesizing dexterous robot demonstrations from human videos via virtual try-on

    RoboTryOn proposes treating human-to-robot transfer as virtual try-on: preserving the demonstrated motion, replacing the human with a target robot specified by a reference image, and keeping the task, objects, and background unchanged. The method autoregressively converts keyframes to guide video synthesis, conditions motion on the human hand skeleton, and then uses an inverse dynamics model (IDM) with fused depth features to infer action labels from the synthesized video for policy learning.
