ShengShu Technology Claims MotuBrain, a Dual-Benchmark Robot Brain for Long-Horizon Tasks

生数科技认领神秘登顶模型：AI视频公司拿出工业级Demo，跨本体跑通复杂长程任务

ShengShu Technology claimed MotuBrain on April 29 after it topped WorldArena and RoboTwin2.0 in mid-April. It scored 95.8 and 96.1 in RoboTwin2.0 Clean and Randomized settings, and a demo used 3 humanoid robots across 5 tasks. The key detail is its World Action Model: a video-action-language MoT design for cross-embodiment tasks beyond 10 atomic actions.

Why it matters: All HKR axes pass: the mystery-model reveal creates HKR-H, while benchmark scores and MoT details support HKR-K/R. Score stays at 82 because evidence is one report plus company demos, not independent deployment data.
