A real-time operating system (RTOS) is a specialised operating system designed to handle time-critical tasks with precision and efficiency.
In manufacturing environments, RTOS is used to control robotic arms, conveyor belts, and quality assurance tools with millisecond precision. This leads to improved system performance, reliability, and overall efficiency.
Let’s take a look at RTOS in more detail.
A real-time operating system (RTOS) is a specialised operating system designed to handle time-critical tasks with precision and efficiency. Unlike general-purpose operating systems (GPOS), which prioritise multitasking and user interaction, RTOS focuses on executing actions in real time.

The concept of real-time computing dates back several decades. The first recognised RTOS was the real-time monitor program developed by Cambridge University in the 1960s. This groundbreaking system allowed multiple processes to run concurrently within strict timing constraints. Since then, RTOS has evolved with technological advancements and the growing demand for reliable real-time performance. With each iteration, these systems have become more robust, efficient, and feature-rich, catering to a wide range of industries such as aerospace, defence, medical science, multimedia applications, and more.
Example in Practice: How NASA utilises RTOS for mission-critical space applications.
Unlike general-purpose operating systems (GPOS) like Windows or Linux, which prioritise multitasking and provide flexibility for various applications, RTOS is designed to handle time-sensitive tasks precisely. The primary purpose of an RTOS is to execute critical operations in a timely manner. It guarantees that certain processes are completed within strict deadlines, making it ideal for applications where timing is crucial. RTOS is also useful for multitasking and task-based work.
RTOS enables real-time control over hardware resources like random access memory (RAM) by providing deterministic behaviour and predictable response times. It facilitates efficient use of system resources while maintaining high reliability and responsiveness. With its ability to manage concurrent tasks effectively, RTOS ensures smooth operation even under heavy loads and varying conditions.

Not all manufacturing companies use RTOS. While they are essential in certain applications that require precise timing and deterministic behaviour, such as robotics, industrial automation and advanced manufacturing processes, they are not universally adopted across all manufacturing sectors.

Resource Management: RTOS optimises the use of system resources, ensuring that critical tasks have the necessary resources to execute properly.
So, the question is whether your manufacturing company should invest in an RTOS.
Many manufacturing companies may use GPOS for less time-critical tasks. The choice between RTOS and GPOS depends on the specific requirements of the manufacturing process, such as the need for real-time responsiveness, the complexity of tasks, and the level of automation involved.
The use of RTOS can lead to significant improvements in manufacturing processes, making it a worthwhile consideration for companies looking to enhance their operational efficiency and product quality.
However, before you decide, make sure that you understand the costs involved as the cost of commercial RTOS can be hefty. It’s also important to note that the total cost of integrating an RTOS extends beyond the initial purchase price. Factors such as development time, staff training, and potential impacts on manufacturing costs due to the RTOS’ resource requirements should be considered. For instance, selecting an RTOS with lower memory and processor demands can lead to reduced manufacturing costs.
Given these variables, it’s advisable for manufacturing companies to thoroughly assess their operational needs and consult with RTOS providers to obtain detailed pricing information tailored to their specific use cases.
