ESTUN robot-specific high-performance servo

As the “powerhouse” of the robot, we adopt ESTUN’s independently developedhigh-performance servo system to ensure extreme precision and smoothresponse during high-speed operation. The system is deeply optimized forbending processes, delivering high torque density and dynamic stiffnessfor faster acceleration and shorter settling time, significantly improvingbending cyele time and trajectory accuracy.

Japanese Nabtesco reducer

The robot’s “joint core” is equipped with Nabtesco’s high-precision reducer,renowned for its excellent transmission accuracy, high rigidity, and longservice life. This reducer effectively suppresses backlash and vibration,ensuring stable and reliable positioning performance even under frequentstart-stop cycles, changing loads, and complex postures, providing solidassurance for long-term, high-intensity operation.

High-quality castings

Key structural parts of the robot body are manufactured using high-qualitycasting processes, refined through precision design, material optimization,and heat treatment. They combine high strength, lightweight design, andhigh dynamic stability, The integrally formed cast components effectivelyenhance overall rigidity, suppress motion deformation and vibration, layinga solid foundation for the robot’s long-term accuracy retentionand durability.
