Applications of CNC in Humanoid Robots
Add Time：2025-09-26
CNC (Computer Numerical Control) technology is primarily applied to high-precision component manufacturing and motion control optimization in humanoid robots, laying the foundation for their flexible movement and structural reliability.
First. High-Precision Manufacturing of Core Components
Humanoid robots require miniaturized, high-tolerance parts to mimic human movement, and CNC machines are irreplaceable in this process:
- Joint components: CNC milling/turning machines produce precision gears, bearings, and reducers (e.g., harmonic reducers) with tolerances as low as +/-0.001mm, ensuring smooth joint rotation without jitter.
- Structural parts: CNC machining of lightweight materials (aluminum alloy, carbon fiber composites) creates robot skeletons and limb frames, balancing strength and weight for natural movement.
- End effector parts: CNC processes grippers or "hands" with fine textures and precise clamping structures, enabling robots to handle small objects (e.g., a pen) stably.
Second. Motion Control and Trajectory Optimization
CNC's mature numerical control logic is adapted to optimize robot movement accuracy:
- Trajectory planning: Similar to CNC machine tool path programming, it pre-calculates the movement paths of robot limbs (e.g., arm lifting, leg walking) to avoid collisions and ensure linear/smooth motion.
- Multi-axis synchronization: Advanced CNC systems support 6 axis control, coordinating the movement of multiple robot joints (e.g., shoulder, elbow, wrist) to simulate complex human actions like "twisting a bottle cap".
- Dynamic error correction: Real-time feedback (via sensors) and CNC algorithm adjustment compensate for motion errors (e.g., slight deviations due to load changes), maintaining movement precision.
