In today’s global wave of smart manufacturing, efficiency and precision have become the core competitive advantages in the manufacturing industry. The new-generation high-speed SCARA robot, meticulously developed by the STEP Zhongweixing brand, boasts exceptional performance—“as fast as lightning yet as stable as a rock”—and pushes beyond the technological boundaries of traditional industrial robots, bringing disruptive innovation to applications such as precision manufacturing, flexible production, and efficient material handling. As a leading provider of industrial automation solutions, the STEP Zhongweixing brand, with 23 years of accumulated technology and unwavering innovation, is redefining the efficiency limits and quality standards of industrial robots.

In May 2025, after 18 months of R&D and iterative improvements, STEPeng Zhongweixing’s SCARA robot product lineup has once again undergone a major upgrade, officially launching the “Yunxia” series of high-speed SCARA robots to the market. This new product series boasts a significant improvement in cycle time, with a standard cycle time of just 0.24 seconds—placing it among the fastest SCARA robots in the industry. It is ideally suited for high-cycle-process applications in fields such as lithium batteries, photovoltaics, food and beverage, and pharmaceuticals.

The “Yunxia” series of high-speed SCARA robots derives its name from the mythical Yunxia beast in Chinese mythology. As the mount of Qingxu Daode Zhenjun, the Yunxia beast can naturally generate clouds and possesses the extraordinary ability to soar through the skies—qualities that perfectly align with the characteristics of the high-speed SCARA robots jointly developed by STEPzhongwei Xing and STEP. Naming this new generation of high-speed SCARA robots after the Yunxia beast better highlights their exceptional speed and agility.

The “Yunxia” series of high-speed SCARA robots features a rated payload of 4 kg, with a maximum payload capacity of up to 8 kg. The arm reach is available in three specifications: 480 mm, 640 mm, and 800 mm. The robots are designed with two installation configurations—normal mounting and inverted mounting—resulting in a total of six models, which effectively meet the diverse application requirements of various automation processes.

The “three swords” of speed, precision, and stability are united in one.

Industry-leading tempo

The standard cycle time is only 0.24 seconds, representing a 30% to 50% speed increase over similar products, achieving “millisecond-level” response speeds and enabling the production line to operate as smoothly as lightning.

Dynamic Path Optimization System

By employing optimal-path and optimal-acceleration algorithms, the system calculates the optimal path in real time and plans the motion trajectory, enabling even complex processes to be completed in one smooth flow and boosting efficiency by 40%.

High-speed synchronous control technology

Multi-axis synchronization with zero latency ensures smooth, jerk-free motion even at high speeds, significantly enhancing the stability of continuous operations.

Repositioning accuracy: ±0.015 mm

Employing high-precision servo motor control technology and dynamic compensation techniques, along with integrated vibration suppression and load-adaptive algorithms, this system maintains long-term stable accuracy even under extreme environmental conditions.

Rigid structural design

Integrated aluminum alloy body + optimized using finite element analysis, enhancing resistance to deformation by 30% and ensuring rigid stability even at high speeds.

Breakthrough in load capacity

Rated load: 4 kg, with a maximum capacity of up to 8 kg; maximum inertia increase of 40%, easily handling heavy materials or loads with high moment of inertia.

Arm span flexibly customizable

Available in a variety of arm lengths ranging from 480 to 800 mm, it can freely extend even in confined spaces, making it widely suitable for process applications such as food packaging, medical devices, new-energy batteries, automotive components, and photovoltaic wafers.

IP Protection Rating Upgrade

Upgrade to the optional IP65-rated version to meet the demands of harsh industrial environments characterized by high dust levels, wide temperature fluctuations, and high humidity.

Hardcore technology sets an industry benchmark.

Self-developed servo drive system

The “Yunxia” series high-speed SCARA controllers adopt ADTECH’s pioneering integrated drive-and-control solution. They feature a servo drive system independently developed by STEP, which reduces energy consumption by 15% and increases response speed by 20%.

High-speed, high-precision harmonic reducer

It uses harmonic reducers from first-tier international brands, offering high transmission efficiency, high precision, low noise, and stable operation. Its designed service life can reach up to 10 years.

Streamlined exterior design

Born from the relentless pursuit of speed, this design features a streamlined shape that further reduces aerodynamic drag. While prioritizing practicality, it includes pre-installed mounting holes for external fixtures and cables, built-in dual Ø6 air lines, and an IO interface with 6 digital input (DI) and 6 digital output (DO) channels.

Modular structural design

The core components are independently modular, enabling rapid iteration of models with different specifications. Their high versatility ensures fast delivery.
