Mechatronics and Motion Control

Mechatronics combines mechanical engineering and electronic engineering in engineering design or engineering discipline. Motion control is the planned, coordinated or managed guidance of moving devices, in rotational motion with motors, pumps, or fans or linear motion or multi-axis motion, in automated machines or stand-alone automation. In industrial applications, computerized motion control via software programs can occur in drives or another logic device, such as computer numerical control, industrial PCs, programmable logic controllers (PLCs), programmable automation controllers (PACs) or in a board-level device. Motors and drives can be integrated in one unit.

Product advice: Smart mechatronics platforms offer new handling solutions

Intelligent mechatronics components, such as linear motion products, controllers, servo drives and operator software with easy-to-use configuration tools, are necessary to build complete, high-performance mechatronics solutions, according to a company with a Control Engineering Engineers’ Choice Award product.

 

Learning Objectives

  • Explore intelligent plug-and-produce mechatronics.
  • Learn how mechatronics can be smarter, with simpler operational control.
  • Understand how smart mechatronics can be applied to various applications.

Many manufacturers are implementing innovative smart mechatronic platforms to build production systems such as compact assembly tools and handling systems. These solutions combine modular components, user-friendly controls and online engineering/commissioning tools that make it easier to specify, order and deploy mechatronics, enhancing their value to original equipment manufacturers (OEMs) and end users.

Through smart, well-engineered integration of linear components and electronic motors, controls and sensors, smart mechatronics provide complete solutions that make it easier for machine builders to build complex manufacturing systems.

The smart mechatronics concept provides a newer, faster approach to creating robotic handling systems like Cartesian robots. Handling robots put together from linear axes are an elementary part of factory automation. They can be found everywhere in the value stream: From incoming goods, production and assembly to packaging applications. They are integrated into individual machines, serve as pick-and-place units and work in semi- or fully automated lines.

Smart mechatronics offer a new approach to creating handling systems that incorporate new features such as advanced sensors and operator-friendly controller platforms that yield real-time data for system performance and manufacturing quality.

The advent of plug-and-produce mechatronics

One of the best advantages smart mechatronics solutions can offer is faster, easier system design and commissioning. Engineers want to streamline how they specify, purchase and commission mechatronics components, using online tools that deliver plug-and-produce systems ready to operate “out of the box” with minimal or no machine programming.

Companies pioneering smart mechatronics solutions are deploying a new generation of online configuration tools that address these challenges. These tools are designed to make it easier for engineers that have just a basic understanding of linear motion and controls requirements to create a complete solution.

This makes it possible to obtain a complete smart mechatronics solution from one supplier that can deliver all the mechatronics — linear modules, controller, electric drives and smart sensors — as an integrated system shipped with preprogrammed motion sequences ready for plug-and-produce implementation.

Mechatronics: Smarter, simpler operational control

Next-level mechatronics handling systems are now able to support transparent production processes with features that enable real-time condition monitoring and predictive maintenance.

These systems are delivered with preinstalled operating software and automatic parameterization of the servo drive, so no motion control programming knowledge is needed to bring it online. It features a drag-and-drop graphical user interface that lets operators intuitively build production sequences.

To set up the handling process, the user selects suitable functional modules from a library via the web-based software, moves them to the correct place in the sequence via drag and drop and completes the parameters. Everything is carried out visually and requires no programming knowledge. The software checks the information entered, as it does during the configuration process, to avoid invalid inputs.

In addition, the data can also be exported via system interfaces to plantwide or cloud-based manufacturing analytics systems, making the smart mechatronics system an integral component of a company’s i4.0 platform.

Mechatronics and Motion Control FAQ

  • What is the meaning of motion control?

    Motion control refers to the technology and methods used to control the movement and position of mechanical systems. This includes the control of the speed, velocity, acceleration and position of the system over time. It can be used in a wide range of applications, such as robotics, automation, transportation and manufacturing.

    Motion control systems use various technologies such as servo motors, stepper motors and actuators to convert electrical signals into precise mechanical motion. They also use feedback devices, such as encoders or sensors, to provide information on the position and motion of the system, which is then used to control and adjust the motion.

    There are different types of motion control systems, such as open-loop systems and closed-loop systems. Open-loop systems do not use feedback and rely on the control signal to drive the system, whereas closed-loop systems use feedback to adjust the control signal, ensuring the system follows the desired trajectory.

    Motion control systems can be used in a wide range of industries, such as automobiles, robots, production lines and medical and aerospace systems.
