Methods and tools - from low-level drivers to advanced algorithms in C++.
How does C++ ensure stability and performance at different layers of automation systems?
C++ is considered the foundation of many robotic applications because it enables a wide range of control over hardware - from direct handling of registers and interrupts to creating complex data structures using modern libraries. As a result, this language serves as a link between computationally demanding tasks and the reliability required in industrial applications.
Low-level drivers and motion controllers.
- Real-time support: Libraries and frameworks in C++ (e.g., in combination with RTOS) help write programs that respond almost instantly to events in the robotic environment.
- Optimization of operations on hardware: Thanks to broad support for SIMD (Single Instruction Multiple Data) instructions and inline mechanisms in compilers, it is possible to further accelerate calculations crucial for control algorithms.
Architecture of ROS (Robot Operating System) systems.
- ROS nodes in C++: The Robot Operating System supports C++ as the main language for writing nodes responsible for communication between robots, sensors, and peripheral devices. This allows for the creation of highly efficient modules with low latency.
- Access to a rich ecosystem: ROS nodes in C++ can use a wide range of packages and libraries (e.g., MoveIt!), which simplifies the implementation of functions such as motion planning, navigation, or computer vision.
Algorithms and data analysis
- Mathematical libraries: Solutions such as Eigen or Boost facilitate advanced data processing (matrices, vectors, numerical functions), which is crucial in projects requiring precise calculations (e.g., kinematics or dynamics analysis).
- AI integration: Although Python dominates the machine learning field, there are AI libraries in C++ (e.g., Caffe, ONNX Runtime), which allows deploying deep neural network models in systems with limited resources (edge devices).
DevOps practices and security
- Code quality control: C++ compilers generate detailed warnings that help detect potential errors (e.g., unsafe pointer operations). Additionally, integration with CI/CD (Continuous Integration/Continuous Deployment) tools enables automatic testing and static code analysis.
- Architecture selection: Depending on the needs (real-time, distributed computing, edge computing), NexaRob helps decide which C++ mechanisms (e.g., co-routines, multi-threading in std::thread) will work best in a given industrial scenario.
Thanks to its wide range of optimization possibilities and full control over the structure of the code, C++ is the foundation for latency-sensitive and computationally intensive control systems. NexaRob supports companies in selecting programming methods and tools so that the designed solutions are not only fast but also easy to maintain and develop in the future.
Case studies and example implementations (general scenarios)
How does C++ solve typical challenges in robot control and automation?
Although each implementation in the field of robotics and automation has its own specifics, many companies face similar challenges - such as the need to achieve deterministic response times, integration with existing systems, or management of an extensive sensor infrastructure. C++ combined with the experience of NexaRob experts can help meet these needs.

Selecting the right environment and compiler
- Compliance with the latest standards: C++11, C++14, C++17, or C++20 offer numerous improvements in memory management and multithreading. It is worth using modern features that improve code readability and security.
- Optimization and profiling: Tools such as GCC and Clang (with built-in profilers) or Visual Studio allow you to track performance in real time, identify bottlenecks, and eliminate unnecessary operations.
Modular architecture and quality verification
- Division into components: Using design patterns (e.g., producer-consumer pattern) facilitates later modifications and scaling of the application.
- Unit and integration tests: In C++, various testing frameworks are available (Catch2, Google Test), which allows you to continuously monitor the stability of functionality and eliminate errors in the early stages of development.
Memory management and security
- Avoiding raw pointers: Using smart pointers (std::unique_ptr, std::shared_ptr) reduces the risk of memory leaks and leads to more readable code, which is very important in applications that run non-stop.
- Access control to resources: Multithreading requires the use of appropriate synchronization mechanisms (mutex, condition_variable) so that robots and processes do not interfere with each other's work.
Using specialized libraries and industry standards.
- Real-time libraries: For real-time (RT) requirements, it is worth using libraries based on embedded systems that provide precise timing and low latency.
- Collaboration with ROS: ROS packages in C++ allow you to easily create nodes that support various sensors, drivers, and communication protocols, unifying the way data is exchanged in the system.
We support implementations C++ from the perspective of software architecture and tools. DevOps., testing, and integration with existing systems. This allows companies using robotics and automation to fully benefit from the performance and reliability of C++, developing applications in a way that ensures their long-term stability.
How conscious design decisions affect efficiency and ecology in industry?
Cost optimization and sustainable development thanks to C++.
By choosing C++ as the foundation for controlling robots or industrial machines, companies can gain not only higher performance but also have a real impact on reducing operational and implementation costs. In an era of increasing environmental awareness and the need for sustainable resource management, well-thought-out C++ solutions become a competitive advantage.
Energy and hardware resource savings.
- Reduced system load: Highly optimized C++ applications run more efficiently on the same components, so there is no need to frequently upgrade hardware or add redundant computing power.
- Extending the life cycle of machines. Stable software controlling the movement of robots or PLCs reduces the risk of failures, which translates into a longer service life for existing equipment.
Better utilization of production lines
- Scalability of solutions: C++ enables the introduction of new functions - e.g., AI modules for analyzing production processes - without major reconstruction of the entire application, which promotes flexibility and efficient response to market needs.
- Reduced downtime: Reliable control programs reduce the number of unplanned downtimes, minimizing losses resulting from delays in deliveries and energy consumption during machine startup.
Compliance with Industry 4.0 assumptions
- Expansion with IoT systems: Using C++, it is possible to implement communication modules for IoT devices, which allows for continuous data collection and analysis in the cloud (Predictive Maintenance).
- Consistent data analysis: Integration of data from sensors, MES reports or vision systems facilitates the detection of areas where efficiency can be further improved and raw material consumption reduced.
Good reputation in the area of CSR (Corporate Social Responsibility)
- Responsible approach to resources: Companies that reduce the number of failures and waste in production gain a better image - they become more attractive trading partners and employers.
- Meeting environmental standards: Thanks to transparent data and controlled machine life cycle, it is easier to implement low-emission production standards, which helps avoid penalties or additional regulatory fees.
We support the analysis of needs and development opportunities so that companies can choose solutions that optimize energy and resource consumption. In practice, this translates into lower costs, a smaller environmental impact, and a stable foundation for further innovation - in line with the idea of sustainable production.
