RV reducers, harmonic drive reducers, and planetary reducers help Construction Robot to operate efficiently

2025-07-02

With advancements in AI, IoT, big data, sensors, and BIM technologies, the construction industry is transitioning from traditional manual/semi-automated methods toward full automation, intelligence, and data-driven operations. Intelligent construction has now become the dominant trend, where construction robots significantly accelerate project timelines and are essential for industry-wide quality enhancement. As critical components ensuring robotic precision and stability, harmonic drives reducer, RV reducers, and planetary gearbox perform distinct roles across various robot subsystems.


Welding Robots


Welding robots guarantee structural integrity through millimeter-accurate welding, far exceeding manual capabilities. Their closed-loop control of motion trajectories combined with stable current/voltage output ensures consistent weld quality. Equipped with machine vision and sensors, these robots dynamically adjust welding parameters and paths while detecting defects in real-time – particularly vital for large-scale structures where they operate safely in confined or elevated spaces inaccessible to humans.

Reducer Type

Technical Rationale

All Joints (6-Axis)

Harmonic Drive + RV Reducer

Hybrid topology balances precision (harmonic) and rigidity (RV) for end-effector trajectory accuracy under payload

Torch Rotation

Spraying Robots

Spraying robots achieve uniform coating thickness through precision control of nozzle velocity, spray angle, and flow rate – reducing material waste by 15-30% (industry data). In human-robot collaboration, operators program parameters (pressure/flow/speed) and map worksites via BIM. Autonomous robots then navigate complex surfaces (walls/ceilings/beams), dynamically adapting to material textures and paint viscosity.
