TL;DR - 机器之心 profiles 信度启源 (Xindu Qiyuan), a newly founded Tsinghua-affiliated startup led by mathematician 刘宝碇, building a robot "brain" on uncertainty theory and "uncertain differential geometry" instead of large data-driven models. It matters as a claimed third technical route for embodied AI — theory-driven and white-box — positioned against end-to-end VLA models and classical control+AI hybrids.

  • The premise: real-world environments violate probability theory's frequency-stability assumption, causing three failure modes in learned models — forced classification of unseen inputs, false confidence (e.g. Wiener-process motion predictions implying infinite path length), and data hunger requiring recalibration per scene.
  • The approach stacks solid geometry → differential geometry → uncertain differential geometry, modeling perturbations as "belief" (uncertain measure) to compute a trustworthy physical boundary, then solving for optimal control inside it — analogous to keeping a safe following distance rather than estimating lane-change probabilities.
  • A "七窍" (seven-module) framework mirrors human cognition: hearing/touch/vision for feature extraction, plus verification (vestibular-like millisecond safety cutoff), prediction (compensates sensor latency to infer the current true state), decision (belief maximization, no action sampling), and control — all non-neural and traceable end to end.
  • Claimed demo: a humanoid grasping a cup at an uncalibrated position at human speed, in an uncut ~10s video, with no task-specific pretraining, no GPU racks, and one month from robot procurement to full deployment. These are vendor/company claims with no benchmarks, ablations, or third-party evaluation provided; the article itself notes scaling to precise assembly, multi-robot, and open environments remains unvalidated. The team is currently raising a new funding round.
