Atlas Large Behavior Model (Boston Dynamics + TRI LBM)
Research collaboration announced Aug 2025 (Toyota release: https://newsroom.toyota.eu/ai-powered-robot-by-boston-dynamics-and-toyota-research-institute-takes-a-key-step-towards-general-purpose-humanoids/). The production electric Atlas (CES 2026) also integrates Google DeepMind foundation models (Gemini Robotics); Hyundai trains Atlas on parts logistics at its Georgia RMAC (2026-09-22). No public weights or API for the Atlas LBM. Exact announcement day (2025-08-20) is from press coverage dated 2025-08-20/21.

Notable capabilities (4)
- One language-conditioned policy for whole-body loco-manipulation: A single end-to-end policy maps images, proprioception and language to actions for the full 50-DoF Atlas at 30 Hz, combining stepping, crouching and center-of-mass shifts with dexterous manipulation in long-horizon tasks, replacing separate walking and manipulation controllers. source
- Diffusion Transformer with flow matching: 450M-parameter Diffusion Transformer trained with a flow-matching objective, predicting 48-step action chunks (1.6 s); trained on Atlas teleop data, the Atlas Manipulation Test Stand, TRI's Ramen dataset and simulation co-training. source
- Inference-time speed-up: Policies can run 1.5-2x faster than the human demos at inference time without retraining by rescaling action timing. source
- Pretraining cuts task data by up to 80%: TRI's LBM study (~1,700 h of robot data, 1,800 real and 47,000+ sim rollouts) found pretrained LBMs need up to 80% less task-specific data. source
Timeline entry
- Boston Dynamics unveils production electric Atlas at CES; Hyundai plans 30,000-robot/yr factory ★★★★
At CES on 2026-01-05 Boston Dynamics unveiled the product version of its all-electric Atlas humanoid (56 DoF, 50 kg payload, self-swapping batteries) and began production immediately; 2026 deployments go to Hyundai's RMAC and Google DeepMind, and Hyundai is building a US robot factory able to make…
