Maintenance Cycle For Key Modules Of Humanoid Robots

The maintenance cycle of key modules in humanoid robots varies depending on the type of module, usage intensity, working environment, and load conditions.

 

Joint Actuators (including servo motors and gear reducers)
Daily Maintenance: Check temperature rise, abnormal noises, sealing, and torque calibration status every day.

 

Lubrication Maintenance
Harmonic/Planetary Reducers: Replace or replenish grease every 1,000–2,000 hours.

RV Reducers: Due to longer lifespan (30,000–60,000 hours), the lubrication interval can be extended to 2,000–5,000 hours.
Key Note: If frequently subjected to impact loads or over-torque, the lifespan may decrease by 30%–50%, requiring shorter maintenance intervals.

 

Motion Controllers and AI Computing Modules
Daily Maintenance: Check cooling system, firmware version, and interface connectivity weekly.

Deep Maintenance
Cooling System Cleaning: Every 500–1,000 hours or every 3–6 months (depending on environmental dust level).
Industrial-grade controller MTBF is 8–12 years, consumer-grade 5–8 years; frequent maintenance is not required, but dust and moisture protection is necessary.

 

Sensor Modules (Vision, Force, IMU, etc.)
Vision/Depth Cameras: Clean lenses and calibrate parameters every 1–3 months; lifespan is about 3–5 years.
Six-Axis Force/Tactile Sensors: Calibrate every 500–1,000 hours; lifespan 5,000–20,000 hours.
IMU (Inertial Measurement Unit): MTBF reaches 8–10 years, generally requires no regular maintenance.

 

Power and Energy Storage Module (Batteries)
Lithium Iron Phosphate Batteries: Cycle life 2,000–4,000 times (to 80% capacity); balance calibration recommended every 50–100 cycles.
Ternary Lithium Batteries: Cycle life 1,000–2,000 times; monitoring needs to be more frequent.
Full Pack Replacement: When capacity declines below 80%, the battery pack usually needs to be replaced, accounting for 10%–25% of the total machine cost.
