Certain components may be subject to different warranty periods due to their usage characteristics. Please refer to the Major Components Warranty Table below.

Category	Scope Description	Standard Warranty Period
Complete machine (standard configuration)	Refers to all hardware components that constitute a complete functional unit, excluding the key components, cosmetic parts, and consumable parts separately listed below.	12 months
Key components	Core components that have a decisive impact on the performance and accuracy of robots, typically including but not limited to controllers, servo motors, precision reducers, high-precision bearings, etc.	Generally 12 months. Certain models or specifically designated key components may be extended to 24 months, subject to the product page, technical specifications, or contractual agreement.
Battery and Charging System	Standard battery modules, chargers, power adapters, and related power supply components. Battery performance degradation is a normal physical characteristic.	6-12 months (subject to the product page, technical specifications, or contractual agreement)
