Manipulation and Perception
30 kg combined dual-arm claim; no per-arm rating, extension curve or cycle duty supplied. Added waist motion versus K2; total DOF, body mass, height and joint limits not verified. Maker describes added waist motion,while K2 V2.1 already lists two waist joints;no numerical K3 joint increment inferred.
WRC maker release describes optional force/tactile/vision/inertial sensing, Orin edge processing and cloud/local models at series level. Exact delivered compute and sensor BOM unverified.
SDK and Integration
Do not apply K2 MotorApi, ROS2 version or Basic/developer rights without explicit K3/K3W compatibility.
| API type | Current K3-series exact API/SDK entitlement unverified |
|---|---|
| Languages | Needs verification |
| ROS support | Public documents inspected target K2; K3/K3W compatibility not established |
| Simulation | Maker uses Isaac platform for training; exact K3/K3W model/controller release unverified |
| Offline operation | Local ROS2 and motor execution documented; cloud model/speech dependencies and full offline feature entitlement unverified. |
| Teleoperation | Specification names VR/motion-capture; remote controller optional. Exact delivered hardware requires quotation. |
| Software updates | OTA claimed; exact update signing, approval, rollback and maintained firmware compatibility matrix unverified. |
| Documentation | Open documentation |
| Integration constraints | Do not apply K2 MotorApi, ROS2 version or Basic/developer rights without explicit K3/K3W compatibility. |
Safety Notes
No K3/K3W exact operating manual, signed conformity declaration or protective-stop validation inspected. K2 lifting/reset instructions cannot serve as this model’s complete manual.
Commercial Readiness

K3 and K3W at WRC2026 ↗
Kepler / PR Newswire · Published Aug 19, 2026 · Accessed Nov 2, 2026
Manufacturer identifies K3 successor with added waist motion, 30 kg combined load, 1 h charging/8 h claim; K3W separates chassis/lift/upper-body motion. Optional sensors and 100 TOPS family marketing do not prove exact edition equipment. Live loading/coffee demos and annual capacity 1000 are not audited customer deliveries. K2 V2.1 already lists two waist joints,so added-waist wording does not establish a numerical DOF increment.

Reporter observes Kepler WAIC demonstrations ↗
Sina Finance · Published Jul 19, 2026 · Accessed Nov 2, 2026
Sina Shanghai reporter Chen Xiuying reports first public K3-series showing and retail/coffee exhibits. Staff explicitly describe quadruped riding product as exhibition-only; that status is not automatically transferred to every humanoid. No independent humanoid production uptime or throughput measured.
