What is mechatronics? Defining a synergistic discipline

Mechatronics is an engineering approach that combines mechanics, electronics, automation and real-time computing. According to standard NF E 01-010 (2008), it is a synergistic integration of these disciplines to optimise the design and manufacture of products. It is not a mere juxtaposition of skills, but an intelligent fusion aimed at rethinking systems for greater performance.

More than a simple addition of skills

Unlike conventional methods in which each field worked in silos, mechatronics simultaneously integrates four key sub-systems: the operative part (mechanical and electromechanical), the control part (electronics and real-time computing), the machine/machine interfaces (networks) and the human/machine interfaces (ergonomics). This collaborative work makes it possible to reduce costs, increase reliability and create modular systems, such as autonomous vehicles or industrial robots.

The origin and the objective: integrated intelligence

The term “mechatronics” was introduced in 1969 by the Japanese company Yaskawa Electric Corporation. The aim at the time was to describe the combination of mechanics and electronics in their products. Today, this discipline aims to design “intelligent” systems integrating sensors, processors and actuators right from the design phase. Applications such as ABS for cars or numerically controlled machine tools illustrate its impact on industrial automation and process optimisation.

The 4 fundamental pillars of mechatronics

Mechanics: the skeleton of the system

Mechanics constitutes the physical structure of mechatronic systems. It includes moving parts, linkages and power transmission. Like a skeleton, it supports the components and allows the necessary movements. Elements such as gears or robotic arms illustrate this function. Ball bearings reduce friction, while linear guidance systems ensure precise movement. In industry, mechanisms such as linear axes guarantee the smooth execution of physical tasks.

Electronics: the nervous system

Electronics links the physical world to the digital one. It integrates sensors (temperature, position) and actuators (motors) to carry out actions. For example, a MEMS sensor (microelectromechanical system) measures accelerations with extreme precision, while a hydraulic actuator converts an electrical signal into mechanical force. Electronics also conditions signals, filtering them for optimal analysis. These components are essential in IoT systems or automotive sensors, such as those in braking systems.

Control engineering: the decision-making brain

Control engineering analyses sensor data via feedback loops in order to calculate the actions to be sent to the actuators. It guarantees stability and precision thanks to algorithms such as PID controllers. For example, in a cruise control system, a sensor measures the actual speed and the controller adjusts the throttle. Critical systems such as ABS brakes or the control surfaces of an aircraft depend on this logic. Closed loops (with feedback) adapt to the environment, unlike open-loop systems.

Real-time computing: the consciousness of the system

Real-time computing runs the control algorithms with instantaneous decisions. It includes human-machine interfaces and communication via protocols such as CAN, synchronising sensors and actuators to avoid errors. Systems such as FreeRTOS or VxWorks provide hard real-time computing (e.g. aeronautical control) or soft real-time computing (e.g. video conferencing). In a connected factory, these tools coordinate sensors with latencies of less than a millisecond, avoiding production defects.

• Mechanical engineering : Physical structure and movement, from gears to robotic arms.
• Electronics: Sensors (MEMS) and hydraulic actuators.
• Control engineering : Analysis via PID loops for stable systems.
• Computing: Real-time calculations and industrial networks (CAN, Modbus).

The mechatronic design process: an integrated approach

From sequential to simultaneous: a paradigm shift

Traditional design followed a sequential logic: mechanics first, then electronics and software, creating disciplinary silos. This method generates costly compromises and delays. In mechatronics, the approach is integrated : mechanics, electronics and computing work together from the initial phase, anticipating the complex interactions between components.

Concurrent engineering (SBCE) transforms this logic. Unlike the “Point-Based” approach, which converges on a single solution, SBCE explores options in parallel. Non-viable solutions are progressively eliminated, integrating production constraints from the outset. This reduces late-stage errors and optimises both the product and the manufacturing system. Companies such as Airbus use this method to validate industrial processes before production.

The central role of modelling and simulation

Multi-physics modelling and numerical simulation guide the V-model, a key method in mechatronics. They virtually validate mechanical, electronic and software performance before physical manufacture. Defects are corrected upstream, limiting the number of physical prototypes. This approach is crucial in demanding sectors such as aerospace.

Digital twins, virtual replicas of real systems, predict breakdowns and optimise maintenance. General Electric has thus reduced unplanned breakdowns by 40 % thanks to this technology. Model-based systems engineering (MBSE) centralises data via languages such as SysML, ensuring consistency between design phases and facilitating international collaboration.

These tools are transforming industry, guaranteeing rapid design, controlled costs and high-performance products aligned with Industry 4.0. International companies, such as those in Luxembourg specialising in industrial performance, thus optimise their competitiveness and anticipate future challenges.

The practical applications of mechatronics in industry

In the automotive and transport sectors

ABS and ESP systems perfectly illustrate mechatronic synergy. ABS combines wheel-speed sensors (electronics), computers (real-time computing) and hydraulic actuators (mechanics) to adjust braking pressure. Without this integration, braking distances would increase by 20 to 30 % on slippery ground.

ESP complements ABS by correcting the trajectory through selective braking and engine adjustments. Thanks to the interaction between gyroscopic sensors and actuators, losses of control in bends are reduced by 40 %. These technologies, resulting from collaborations between Bosch and the manufacturers, prevent 15 000 serious accidents a year in Europe.

In robotics and production

Industrial robots, equipped with torque sensors and servo-control algorithms, achieve an accuracy of 0.02 mm in automotive assembly. Cobots, incorporating real-time force sensors, work safely alongside humans, reducing errors by 60 % in machining lines.

AGVs (automated guided vehicles) use mechatronics to navigate via laser beacons and on-board computers. At Amazon, these robots optimise logistics flows, making it possible to handle 300 000 parcels per hour in European warehouses. CNC machine tools, synchronising stepper motors and CAM systems, produce complex parts with nanometric repeatability.

• Aeronautics: The electric flight controls (fly-by-wire) of the Airbus A380, with redundant sensors and fault-tolerant computers.
• Medical: Da Vinci surgical robots, combining inverse kinematics and 3D imaging, enabling sub-millimetre dexterity.
• Consumer goods : Image stabilisers in smartphones, integrating MEMS accelerometers and linear motors.
• Defence: The guidance systems for missiles and vehicles, using fibre-optic inertial navigation units for an accuracy of 0.001 degrees.

Mechatronics, Industry 4.0 and sustainable development: tomorrow's challenges

By merging mechanics, electronics and computing, mechatronics is becoming the foundation of Industry 4.0. It makes it possible to meet ecological challenges while optimising industrial processes. Which synergies between these fields are shaping our industrial future?

A pillar of Industry 4.0

Mechatronic systems embody the industrial Internet of Things (IoT). Connected via sensors, they generate data used by artificial intelligence (AI) to optimise production. Digital twins thus simulate physical processes in real time, anticipating breakdowns and improving maintenance.

Concrete examples: industrial robots driven by mechatronic systems automate assembly, while intelligent actuators adjust energy flows. Cyber-physical systems, such as the “all-in-one” motors from Sew Usocome, integrate drive, gearbox and motor to reduce energy losses. These innovations simplify installation thanks to a compact architecture, limiting the wiring and space required.

Thanks to the integration of embedded software, machines adapt in real time to the specific features of production batches. This reduces scrap and optimises the use of raw materials, aligning industrial performance with energy efficiency.

Meeting the challenges of sustainable development

How does mechatronics reduce the ecological footprint ? In three ways:

• energy efficiency : systems such as Poclain Hydraulics' CleanStart shut down the engine when it is not needed, saving 2 000 litres of fuel a year. On-board drives, such as those in the BCS 600 intelligent transmissions from Siam Ringspann, adapt to dynamic loads for optimal braking.
• Predictive maintenance : NTN-SNR sensors, powered by the energy of the bearings, anticipate wear. This avoids unplanned stoppages and limits waste. Data analysis using techniques such as Principal Component Analysis (PCA) makes it possible to condense the critical indicators for targeted intervention.
• Material optimisation : Poclain Hydraulics' AddiDrive transmissions, active only on demand, save 15% of fuel while reducing the size of components. The use of composite materials in lightweight drivetrains reduces equipment weight without compromising robustness, as in aeronautics.

Industry gains in energy efficiency thanks to this approach. By integrating electronics and advanced modelling, mechatronics is reinventing sustainable production. The initial additional costs are amortised in less than a year thanks to the savings achieved, proving that ecology and profitability can coexist. Guides such as those from Artema standardise best practice for pneumatic efficiency, illustrating this synergy between innovation and sustainability.

From technician to engineer: varied career paths

Mechatronics profiles are distinguished by their level of training and their role in industrial projects. The senior technician (two to three years of higher education) works on the implementation and maintenance of existing systems, with hands-on expertise in PLC programming and technical diagnostics. The engineer (five years of higher education) focuses on innovative design and research, leading complex projects combining advanced modelling and system integration.

Industrial sectors such as automotive, aeronautics and robotics show strong demand for these profiles. Why this difference in salaries? The engineer brings a strategic vision in R&D, while the technician ensures day-to-day operability. Despite common foundations in mechanics and automation, their responsibilities determine their place in the industrial value chain. An engineer might design automation systems, while a technician would manage their deployment.

The technical and interpersonal skills in demand

Why are mechatronics experts in such demand? Their technical versatility. Beyond the traditional pillars (mechanics, electronics), they master critical tools such as the Kalman filter for state estimation, or ROS (Robot Operating System) for robotics. Programming in C++/Python is becoming an essential skill for embedded systems.

• Analytical and synthesis skills : To understand complex systems.
• Multidisciplinary teamwork : To communicate effectively with all the experts.
• Complex problem solving : To diagnose and innovate.
• Creativity and curiosity : To imagine tomorrow's solutions.

Companies are also looking for profiles able to handle challenges such as the miniaturisation of components. 93,6% of mechatronics engineers in Quebec receive employee benefits – international recognition of these professions. This trend is explained by industrial digital transformation, a key field for Luxembourg companies specialising in industrial performance.

Why mechatronics is essential for industrial performance

How can safety, cost reduction and innovation be combined in industry? Mechatronics, combining mechanics, electronics, automation and real-time computing, is transforming the design of systems. Players such as NTN demonstrate its impact on industrial production.

First, it optimises working conditions. By automating arduous tasks (lifting, positioning), it limits musculoskeletal disorders (MSDs) and frees operators for more rewarding work. Remotely operated systems keep workers away from hazardous environments (extreme temperatures, toxic products), reinforcing safety and comfort.

It then boosts productivity. The integration of sensors and algorithms makes machines autonomous and precise. Studies show a 30 % improvement in process reliability, with less downtime. Innovations such as ASB® instrumented bearings allow real-time monitoring of machine condition, anticipating breakdowns.

Finally, mechatronics is a lever for digital transformation. It designs intelligent systems able to adapt in real time. In an Industry 4.0 context, this technology reduces energy costs, extends equipment service life and opens the way to innovation. For a Luxembourg company specialising in industrial performance, mastering this discipline is essential to anticipate the challenges and stand out in a changing sector.

Mechatronics combines mechanics, electronics, control engineering and computing for greater performance and reliability, reduced costs and accelerated innovation. Essential to Industry 4.0, it enables companies to digitally transform their processes efficiently. Mastering this synergy is a key competitive imperative.
