Innovative Thinking

As technology becomes more prevalent, machines are now being used to build other machines. Most of the robots produced are shipped to various factories where they play a key role in the manufacturing of cars, laptops, and other equipment. It has been reported by Loup Ventures that as more people are swayed towards gadgets, the market for industrial robots is bound to grow over 175 percent over the next decade.

But the dynamic is going to change as well. The driver of this growth won’t consist primarily of industrial arms joining car parts as they have been for decades. Instead, a new generation of robots is taking over that is smarter, more compact, and much more collaborative than the traditional industrial robot. These collaborative robots will account for a large percentage of robots sold in future decades throughout industries. To compare, collaborative robots today only account for 3 percent of industrial robots.

Previous deburring methods required a lot of time and effort to occur. An operator would unload cut parts from a plasma cutting machine, reload a sheet, and then manually grind the burrs and slagging off any edges. Once the operator finished grinding, the ground parts are retrieved by a material handler and carried away. These steps are repeated over and over, with the next batch of cut parts being unloaded, and going through the hand-grinding process. While the operation may sound coordinated to someone who runs a low-volume establishment, the truth is this kind of work is difficult and prone to issues on a wide scale.

The Factory of the Future, better known as Smart Factory, is a paradise of efficiency where words like defect, downtime, and delays exist only within historical facility logs. The facility is powered by a web of interconnected devices operating together in harmony for the satisfaction of clients and customers within time frames, and at a manageable cost.

Such a factory represents the epitome of technological development, illustrating a perfect mix between high-tech tools and skilled workers that complement each other. And while this may still be a fantastic dream, its much closer than one might think.

Many of the technologies that are changing the fabric of the society are also entering other sectors such as material handling. Warehouses and distribution centers are now faced with concepts such as Internet of Things, Artificial Intelligence, and Big Data. These concepts can greatly improve the efficiency of the establishment, but they can possess a steep learning curve.

While still new to the industrial world, these concepts are already finding use within industries that will serve as proving grounds for new material handling technologies. The future of warehouse management is dependent on a handful of key technologies that include Big Data and the Internet of Things.

HMIs, or human-machine interfaces, allow easy control and interaction between operator and machine. However, the data they collect can be underutilized. This is why integrating historians with HMIs is recognized as an effective data collection method.

Historians are software for data collection which can then be stored in spreadsheets, files, and other database products. This allows the information to be accessible for reporting on different trends and to refer back to later on. HMIs allow the data to be seen in real time before the historian software records it, as well as historical data replay if the HMI/SCADA is set up properly.

Multiple sensors are often used for measuring parameters in controlled processes. In such cases, cascade control systems offer a much more viable and better choice than traditional single-measurement controllers. For instance, a temperature sensor that measures and alters the valve actuator in a steam-fed water heater may seem like a complete solution, but it would start to bottle-neck once multiple parameters start chipping in, such as mechanical friction.

Renewable energy is by far the best way to limit dependency on fossil-fuels, and stop the deteriorating situation of the environment, globally. However, the current power system is a stark reminder of legacy technologies, not to mention highly dependent on age-old principles and techniques, putting up hurdles for the integration of renewable energy plants.

In addition, transmission and distribution networks often face project delays, due to reasons such as right-of-way, resistance from activist groups, and limited financing options.

There is no one-size-fits-all solution in the world of manufacturing. Automating processes is a complex issue, with robots ranging from the size of an insect to as powerful enough to move automobile chassis. In recent years, a new term has been coined by manufacturers and machine builders to define a breed of robots that can work in conjunction with human presence: collaborative robots, or cobots.

The widespread adoption of power electronics in the industrial sector did lead to astonishing energy savings, however at the same time it also increased the presence of a negative factor within the electric grid: Harmonics.

Harmonics are voltage & current waveforms that are sinusoids with frequencies that are some multiple of the base signal’s frequency. Normally, the world follows a pure sinusoid of either 50Hz or 60Hz. When a harmonic of 3rd order is introduced at a 60Hz power system, a component of frequency 180Hz is added to the system. This in effect, distorts the shape of the voltage & current signal that is fed to the appliance/component/machine. Example of non-linear loads include battery chargers, UPSs, VFDs, LED drivers, electronic ballasts, etc., most of which are usually found within commercial or industrial buildings.

Pittsburgh was once as renowned for pollution as it was for industry and manufacturing. Decades after the Smoky City cleaned up its act and became a modern pillar of education, healthcare, technology, and finance, many people still associate Pittsburgh with a coal-gray haze.

Now manufacturing itself has undergone a millennial renaissance, yet it still carries a bad reputation as dirty and dangerous work.

But like Pittsburgh, the nature of industry has changed.
