Answers About the Use of C++ in Robotics, Control Systems and Industrial Projects
Frequently Asked Questions
Below we present nine popular questions that often arise in the context of C++ programming for the automation industry. If you do not find an explanation for your question here, contact us. NexaRob will be happy to advise you on how to use the full potential of C++.
C++ offers greater control over hardware resources, which requires more attention to memory management and multithreading. However, modern standards (C++11/14/17/20) introduce many conveniences, and well-organized training can reduce the learning curve to an acceptable level.
Especially where deterministic response times and computational performance matter: real-time control, motion planning (kinematics), processing large volumes of data from 3D sensors, or calculations in vision systems.
Yes. Many robot manufacturers and frameworks (e.g. ROS) allow modules to be created in different languages. For example, critical calculations are written in C++ for speed, while higher-level logic can run in Python using convenient prototyping libraries.
ROS supports C++ nodes as one of its core options. This provides close integration with ROS libraries and enables the development of high-performance modules within an ecosystem of nodes responsible for communication, planning and sensor-data analysis.
Although Python is more commonly used for AI prototypes, machine learning libraries dedicated to C++ are also available. This makes it possible to deploy an AI model on a system with limited computing resources, such as an edge device, or where deterministic execution times are required.
Popular compilers such as GCC, Clang, and MSVC provide profiling tools and detailed code-level warnings. Solutions such as Valgrind or Visual Studio Profiler can also be used to detect memory leaks, excessive CPU usage, or thread deadlocks.
Depending on the type of application and architecture, for example modular ROS systems, partial updates can be performed without interrupting the operation of the entire system. However, in critical industrial processes, planned service downtime is usually used to ensure that the whole system has been properly tested.
We offer comprehensive services, from needs analysis and software architecture design to implementation and long-term service support. We also provide team training so that engineers can develop and maintain the code independently.
C++ is used in many cobot controllers and platforms. Its performance and low-level control enable precise management of movement and interaction with the environment (e.g. force sensors). In practice, this means faster responses to changes and safer cooperation with people.
