TECHNICAL SUPPORT
Published 2026-01-19
Picture this: a precision robotic arm assembling tiny parts. The servo motors of each joint need to be perfectly coordinated, the signal cannot be delayed, and the instructions are clear. But the control system behind it was in a mess - the modules were intertwined with each other, and if a function was updated, the entire production line would have to be shut down for debugging. Is this scene familiar? Many projects are stuck on the old path of system architecture when it comes to the coordination of machinery and electronic control.
This is like using a heavy gear set to drive a steering gear that requires sensitive response. It's not that the motor is bad, but the transmission method is holding it back.
A traditional single system is like welding all circuit boards, sensors and motor controllers to the same base plate. It seemed like a no-brainer at first, but as functionality increased, the wiring became tangled. Do you want to upgrade the servo feedback? You may have to recompile the entire core program. A certain sensor library version is incompatible? The entire system can become unstable.
People often ask: "Our equipment is running well, why do we need to bother with the architecture?" The answer lies late one night in the future. When you need to quickly connect a new inspection station, or let the three-axis motion platform fine-tune parameters independently of the main system, the feeling of powerlessness that affects the whole body is the price.
Faced with this dilemma, two ideas are often heard: microservice architecture and service-oriented architecture. They sound very technical, but the core idea is very pragmatic - break down a large system into a set of small units that can work independently and communicate easily.
Microservices are like equipping each workstation in your factory with an independent smart control box. Each box only deals with one thing, such as specifically processing the torque control of the servo motor, or specifically analyzing the point data of the visual sensor. They exchange information through simple standard interfaces, such as several explicit APIs. If one box malfunctions or is upgraded, the other boxes will function as usual.
SOA is more like establishing a set of communication protocols and switching hubs common to the entire factory. It emphasizes the unified management and reuse of services, and may be coordinated by a centralized service bus. For example, all modules that require location information subscribe to the same "location service" for data.
Which one is better? This is like asking "It is better to use step control or torque control for servo motors". There is no single answer, only a more appropriate situation.
existkpower, we deal with servo motors and precision machinery all year round. We have observed that the control architecture of a good electromechanical system often reflects the wisdom of the physical world.
You see, the layout of the electrical cabinet of a complex machine tool is not chaotic. Power lines, signal lines, and communication buses are arranged in layers, isolated from each other and clearly connected through interfaces. This in itself is a kind of "service-oriented" thinking at the physical level. We bring this pursuit of reliability and clear boundaries into the design of the system architecture.
We don't blindly recommend any one architecture. Just like not all robotic arms are equipped with the same model of servos. We will sort it out with you: Which functions change most frequently in your project? Which modules require the highest real-time performance? What data are the basic resources required by multiple parts?
For example, if your system needs to frequently iterate different motion controls, then separate the "motion control service" into a microservice to achieve hot updates without disturbing others. If multiple subsystems of yours require the same calibration data from a high-precision encoder, then a centralized, robust "data service" may be more in line with the SOA concept to avoid data redundancy and consistency issues.
In fact, microservices and SOA are not completely separated. In complex mechatronics projects, a hybrid model often works better. You can use the idea of microservices to dismantle those highly cohesive functional modules (such as independent temperature control units, vibration compensation), and at the same time use the SOA concept to build some basic services shared by the whole system (such as device identity management, unified log center).
The benefits of this are immediate. Flexibility: You can replace a certain functional module just like replacing a servo drive without having to stop production for overhaul. Serviceability: Problems are isolated within independent services, and can be located and fixed as clearly as troubleshooting a single circuit board. Technology diversity: Different services can use the technology stack that is most suitable for their tasks. For example, C++ is used for high real-time requirements, and Python is used for upper-layer logic, without interfering with each other.
More importantly, this architecture gives the system the ability to grow. When you need to add a collaborative robot unit in the future, or connect to an IoT platform for data analysis, you only need to add new services and talk to existing services, rather than reinventing the wheel.
Moving to a clearer architecture is not an immediate switch. It's more of a step-by-step journey. You can start with a module with the most pain points, encapsulate it as a service, and experience the benefits of its independence. Then gradually expand.
In this process, Kpower prefers to play the role of a partner. We not only provide components, but also share our thoughts on "how to make complex systems run simply and reliably" accumulated from countless electromechanical integration projects. We believe that a good technical solution is like a carefully tuned servo system - it responds quickly, runs smoothly, has clear boundaries, and always leaves room for the next evolution.
When you no longer need to worry about coupling within the system, and when you can focus more on mechanical innovation and functionality, you will feel that a good architecture brings a silent and solid power. It is not noisy, but supports all precise and efficient operations. This may be the goal we pursue together with Kpower in many projects.
