SPG reducers integrated into KAIROS humanoid standard drive modules
SPG precision reducers were integrated into standard drive modules for KIMM’s KAIROS humanoid, establishing a named platform qualification for the supplier.

Evidence notes
- The reducers are used in KAIROS drive modules at the waist, hips and ankles.
- The hardware outcome follows an actuator-development agreement signed with KIMM in October 2025.
- KIMM is targeting KAIROS V1 for April 2027; the disclosure does not establish commercial-volume reducer shipments.
