STEPStduio is a software platform independently developed by STEP Automation, specifically designed for offline programming and simulation of industrial robots. It helps users perform offline programming, simulate complex robotic motions, and conduct real-time monitoring and optimization of production processes. Following the latest upgrade of STEPStudio, four key new features have been added: integrated ADTECH robot support, digital twin-based monitoring, collision detection, and highly detailed simulation of gripping actions. We will provide a detailed introduction to these features in this article.

Highlight 1: Integrated ADTECH robot

ADTECH is one of China’s leading brands in industrial robotics and an important component of our company’s robotics business. Its product lineup includes cleanroom robots, semiconductor wafer robots, and integrated drive-and-control systems. Core technologies such as multi-axis synchronous control and high-precision motion algorithms have broken foreign monopolies and are widely used in industries including 3C electronics, semiconductors, and automotive. As a national-level “Little Giant” specializing in niche expertise and innovation, as well as a Guangdong Province Manufacturing Single Champion, ADTECH continues to enhance its competitiveness in the high-end manufacturing market through localized services and rapid response capabilities.

STEPStudio_V4.5 integrates ADTECH-brand robots, providing support for further development.

• Robot library extension, supporting ADTECH robot library robots

We have expanded the 21 commonly used ADTECH robots and ensured that each robot’s DH parameters, dynamics files, and torque files are completely consistent with those of the actual hardware.

• Integrated ARStudio

To ensure that ADTECH robot users can continue using their familiar workflows, STEPStudio_V4.5 integrates ARStudio. Users can write AR programs in the way they’re accustomed to, and then launch simulations within STEPStudio to perform beat tests.

Virtual Verification and Maintenance of Production Lines

• Collaborative simulation with STEP robots

In fields such as high-precision assembly, electronic manufacturing, and automotive component processing, the collaborative application of six-axis industrial robots and SCARA robots maximizes efficiency by leveraging their complementary strengths. In terms of precision, the SCARA robot offers ±0.01 mm accuracy in the XY plane, while the six-axis robot achieves spatial orientation accuracy of ±0.05 mm. In terms of cycle time, the SCARA robot efficiently executes 80% of standardized tasks at high speed, whereas the six-axis robot handles the remaining 20% of complex operations, resulting in an overall OEE improvement of 35%. Furthermore, the SCARA robot optimizes space utilization by operating in compact areas, while the six-axis robot covers a larger working envelope, reducing workstation footprint by 30%. Simulation of the collaborative application between six-axis industrial robots and SCARA robots can be realized in STEPStudio_V4.5.

Digital Twin Monitoring

Robot The practical significance of using simulation software to implement digital twins and real-machine monitoring lies primarily in three key dimensions: cost reduction and efficiency enhancement, risk control, and intelligent decision-making—transforming traditional manufacturing models altogether. Specifically for the application domain of industrial robots, leveraging STEPStudio as a platform and relying on virtual 3D twin technology and intelligent control technologies, we can establish a one-to-one virtual space that integrates digital and physical signal control. By adopting the technical concept of "using the virtual to replace the real and using the real to control the virtual," we achieve seamless interaction between the physical and virtual worlds, thereby realizing true digital twin applications.

(1) Using STEPStudio, we have built a virtual working environment that closely mirrors the real world, enabling a model mapping of workstations from the physical world to the virtual world. This includes all physical entities such as robots, additional axes, positioners, tools, quick-change devices, and conveyor belts.

(2) Connect the simulation software. At this point, click “Connect to Real Controller” to complete the connection between the physical workstation and the virtual workstation.

Turning the real controller on and off

(3) Conduct synchronous virtual-real simulation by mapping the real-time motion controller data of the robot to the simulation system, thereby enabling digital twin monitoring. This allows you to monitor the robot’s operational status, collect data, record videos of the robot’s operation, review the robot’s running process, and troubleshoot any issues that may arise.

Collision check

The core significance of using robotic simulation software for collision checking lies in shifting the trial-and-error costs from the physical world to the virtual space, thereby achieving zero-risk, high-efficiency production assurance. Its significance is as follows:

• Directly avoid substantial financial losses by preventing hardware damage and production line downtime; eliminate the risk of product scrap.

• Shorten the production line deployment cycle

• Ensure the safety of human-robot collaboration

The STEPStudio_V4.5 version adds a collision detection feature that performs collision checks during the simulation process. By eliminating collision risks at the virtual stage, enterprises can achieve a closed-loop smart manufacturing system characterized by “zero physical collisions, zero unplanned downtime, and zero safety incidents.”

Fine-motor simulation of grasping tools

The core significance of using robotic simulation software to simulate fine tool movements—such as gripper opening and closing, welding torch ignition, and the like—lies in achieving precise rehearsal and optimization of micro-level motions, thereby transforming the hidden costs associated with physical debugging into digitally controllable parameters. The implications are as follows:

• Avoid micro-scale production accidents, such as preventing gripping failures and providing tool interference warnings.

• Optimizing process parameters to reduce costs and improve efficiency—for example, virtually debugging the motion parameters of grippers. In STEPStudio_V4.5, a simulation feature for fine tool movements has been added. By using this feature, we estimate that tool debugging costs will decrease by 78% and the debugging cycle will be shortened by 90%.

STEPStudio is better equipped to meet the modern manufacturing industry’s demands for efficient, flexible, and precise production, helping enterprises stand out in the fiercely competitive market. Looking ahead, STEPStudio will continue to focus on technological innovation, providing users with higher-quality, smarter solutions and driving the robotics design and manufacturing industry to new heights.
