2025-11-01
Harmonic reducers have become the core components of high-end robots due to their low backlash characteristics, and domestic enterprises such as Green Harmonic have achieved 60% market coverage in China.
The driving system provides motion power for robots, mainly divided into three types: hydraulic, pneumatic, and electric. Hydraulic drive uses oil as the medium, with high driving force and smooth motion, suitable for 2300kg heavy-duty robots, but there are issues with leakage and noise; Pneumatic drive utilizes compressed air for operation, with low cost but insufficient accuracy, and is mostly used for simple grasping scenarios; The mainstream of modern robots adopts electric drive, which uses servo motors combined with RV reducers or harmonic reducers to achieve high-precision motion control. Brands such as Braun use this combination to control the repeated positioning error within ± 0.02mm. Among them, harmonic reducers have become the core components of high-end robots due to their low backlash characteristics, and domestic enterprises such as Green Harmonic have achieved 60% market coverage in China.
