World-model developer ShengShu Technology (生数科技) released Motus2, adding a lightweight tactile-expert module that refines manipulation actions using touch feedback.

ShengShu Technology (生数科技) released Motus2 on September 12, describing it as a self-evolving general-purpose world model for dexterous manipulation. The specific technical update disclosed concerns contact during manipulation tasks.

Motus2 introduces a lightweight tactile-expert module that refines actions using the latest touch feedback. The stated function is to give action adjustments a contact-based input beyond vision, rather than relying solely on visual observations.

The source does not disclose model size, tactile-sensor configuration, training compute, task-success rates, or comparisons with earlier versions. It also provides no mechanism or benchmark supporting the broader “self-evolving” description, so no quantified manipulation improvement can be established from this announcement.
