TECHNICAL SUPPORT
Published 2026-01-19
You are hard at work debugging the robotic arm of a piece of equipment. The servo feedback signal is a bit delayed, and several modules on the production line always "fight" during data transmission. When you stare at the drawings and codes, it feels like you are unraveling a mess - one hair trigger affects the whole body. Modifying one function may require turning the entire system upside down. test? That would be even more of a nightmare. If one link is unstable, the entire line may stop. Sound familiar?
Many people will encounter this "bloated" problem when building complex mechatronics systems. All functions are tightly coupled together, like a solid iron block. It takes a lot of effort to move one of the small gears. This directly slows down innovation and response.
Is there any way to make this "piece of iron" more flexible? Of course there is. This is why the "Design Principles of Microservice Architecture" are particularly valuable when solving such complex system problems. It is not a concept that appears out of thin air, but was born to solve rigid problems in actual engineering.
Imagine what would happen if we split that huge control system into independent and focused small modules? For example, let the module responsible for position control run independently, let the module that processes sensor signals be self-contained, and then separate the module that manages the communication protocol separately.
Each small module is a "microservice". They each have clearly defined responsibilities, like an engineering team with clear divisions of labor. The position control group only focuses on calculating trajectories, and the sensor group specializes in signal filtering. They "talk" to each other through well-defined, lightweight interfaces (such as simple messages or APIs), instead of all code and memory being mixed together as before.
What is the most direct benefit of doing this? Independent and agile. When you need to upgrade the control of the servo, you only need to modify and publish the service module specifically responsible for control, without disturbing the entire system. Testing also became focused and could independently verify this new effect. If a problem occurs, the specific service can be quickly located, repair and rollback are easier, and there will no longer be the embarrassment of "a fire breaks out in one place and the entire building is evacuated."
However, splitting is not a simple “one size fits all” approach. If there are no good design principles to restrain you, you may fall from a "mess" into a "pile of loose sand". Confusing calls between services, inconsistent data, complex deployment...new problems will emerge one after another.
What design principles can really help? It should guide you in building an organic whole that is both independent and synergistic.
A core principle is "Modeling around business capabilities". This is not a pile of technical terms, but based on practical issues. Ask yourself: What is the core and most frequently changing “business” in the system? Is it motion trajectory planning? Is it real-time status monitoring? Or troubleshooting? Each independent business domain can become the design boundary of a microservice. This ensures that what each service does has real value, rather than a forced separation of technologies.
There should be "loose coupling and high cohesion" between services. To put it simply, each service must work closely together (high cohesion), while services must remain relatively independent, with as few dependencies as possible (loose coupling). Just like the joint module of the robotic arm and the power module of the base, they need to work together, but their respective internal mechanical structures and control circuits are independent and can be repaired or upgraded separately. Achieving this often relies on clear interface contracts and asynchronous communication to avoid long "waiting" and "blocking" between services.
Furthermore, don’t forget about “independent deployment and scaling”. This is a key manifestation of the flexibility that microservices bring. Each service should be able to be individually packaged, deployed, and scaled horizontally. When a certain service (such as a module responsible for large amounts of data calculations) becomes under pressure, you can add "replicas" to it individually without having to scale up the entire huge monolithic application. This is like adding a robot at a key station to a busy production line, rather than blindly expanding the entire factory.
Of course, there are also principles such as decentralized data management and automation and fault-tolerant design. The former allows each service to manage its own "exclusive data", reducing competition for the global database; the latter uses automated deployment, monitoring and circuit breaker mechanisms to make the system more robust and able to tolerate the temporary failure of a single service.
After talking about so many principles, you may be thinking: This sounds a bit abstract, but what does it mean for the specific servo motor and robotic arm projects I am working on?
This means you can deal with complexity with a clearer architecture. For example, you can design a dedicated service to encapsulate all the drive logic and calibration of a certain type of servo. When it's time to replace or upgrade your servo model, this service makes replacement very clean. For another example, you can make the visual positioning module an independent service. When iterating, other parts of mechanical control and motion planning will not be affected at all.
It makes your system more like Lego bricks rather than a piece of carved plaster. Combining, replacing, and upgrading are all easier. The iteration speed, reliability and maintainability of the project will all reach a higher level. For electromechanical projects that require rapid response to demand changes, integration of multiple hardware, or continuous performance improvement, this architectural advantage will gradually transform into real competitiveness.
When we talk about incorporating these proven design concepts into products,kpowerThe focus is on how to transform them into a stable, efficient reality. This is not about paper talk, but about how to put your next complex project on a clearer and more controllable path, starting from the underlying architecture. After all, good basic design often determines how far and how stable the superstructure can go.
Next time you are faced with a complicated system drawing and feel a headache, maybe you can change your mind: Can it be designed as a group of "small teams" that collaborate with each other? This may be the beginning of unraveling the mess.
