Record changelog
- Battery Life: 4–6 hours → 4–6 hours (supports plug-in) · Jul 6, 2026
fix: official 'Endurance: 4~6hours, supports plug-in'; numeric = conservative floor
- Degrees of Freedom: 14 → 14 (2 × 7-DoF arms, derived) · Jul 6, 2026
label fix: official states 'Single arm DoF: 7'; 14 is a derived arms-only total; whole-body DoF not disclosed
- Max Speed: 10 m/s → ≥10 m/s (end effector) · Jul 6, 2026
label fix: official 'Maximum velocity at the effector: ≥10m/s' is arm end-effector velocity, not locomotion speed (S1 is stationary)
- Payload Capacity: 10 kg → 5 kg per arm (horizontal reach) · Jul 6, 2026
fix: official 'Payload per arm (horizontal reach): 5kg'; prior '10 kg' was an undocumented two-arm sum
- Reach: 194 cm → 1940 mm (arm span) · Jul 6, 2026
fix: official states 'Arm span: 194cm'; no per-arm reach disclosed; row held numeric 194 rendered as '194 mm'
- Height: 170 cm → 1700 mm · Jul 6, 2026
fix: official 'Height: 170cm'; row held numeric 170 rendered against canonical mm -> page showed '170 mm'
