ロボティクスとフィジカルAIの最新論文と、それぞれが産業にもたらす意味。
Voluntary movements have long been hypothesised to be comprised of discrete primitives called submovements, as a descriptive model of human motor behaviour. However, existing methods scale poorly, and no principled method exists to determine whether a decomposition is informative.
ロボットAIモデルは先の動作をひとまとまりで予測するが、そのうち何ステップを実行してから周囲を見直すかは、これまで技術者が固定値で決めることが多かった。清華大学や北京智源人工知能研究院（BAAI）などによる今回のプレプリントは、この値を動作中に自動で選ぶ追加モジュールを示し、Physical IntelligenceとNVIDIAの既存モデルを再学習せずに、シミュレーションと実機の双腕ロボットで成功率を高めた。
Robot policies are frequently trained from human corrections, yet teleoperating a robot to provide corrections is burdensome, and human demonstrators are not always optimal. We propose Blended DAgger (BlenDAgger), an approach for collecting data to train imitation learning policies by using shared control to blend the policy's and demonstrator's actions during interventions.
While contact-rich manipulation requires deliberate regulation of interaction forces, recent approaches to robot manipulation learning predominantly represent actions as target positions or poses. Even methods that incorporate force sensing either use it solely as an observation or, when predicting forces as part of the output, rely on a hybrid force controller.
Co-training a VLA on heterogeneous data (multi-robot, web, high-level subtask labels) lets a mobile manipulator clean unseen homes end-to-end.
