A ball-screw–based robot actuator architecture improving back-drivability and force reflection for humanoid finger/arm joints — early foundational humanoid actuation IP.
Claims
Claims cover a rotation source, ball screw and nut, parallel guide, slider, and a connection member enabling relative motion that improves force reflection and back-drivability of the actuator.
Technical analysis
Before today’s harmonic/planetary wars, ball-screw linear-to-rotary packs were a leading humanoid approach. This Samsung filing is evergreen context for why modern hands still obsess over back-drivability and force reflection.
Commercial impact
Historical but still cited in humanoid actuator prior art. Useful evergreen explainer content for readers comparing Optimus/Apollo hand drivetrains to earlier humanoid lines.
