At some point during a philosophy 101 class, college students learn about Aristotle’s belief that the best way to understand something is to break it down to the smallest components. For an increasing number of manufacturers and integrators, however, the best way to assemble a product is to use a machine built with modular automation components that quickly and easily fit together.

Power tools collect a wealth of data about the fastening process. With some simple statistical analysis, engineers can obtain valuable insight into the fastening process.

Vision systems play a vital role in automated assembly systems. They can check for the presence or absence of parts or materials. They can measure key dimensions of assemblies. They can tell robots the precise location of parts. They can even read 1D and 2D codes.

In the nautical disaster movie, “The Perfect Storm,” three weather fronts converge off the coast of New England to create one of the fiercest storms in U.S. history. A similar convergence is occurring in the manufacturing world today. It’s called Industry 4.0 and it promises to transform the way that engineers design and build products over the next two decades.

This time of the year, many homeowners in the Midwest and Northeast start covering their barbecue grills, patio furniture, rosebushes and swimming pools. The type of cover they choose can make a big difference in how those objects survive cold winter temperatures and heavy snow.

Cell phones, tablets, GPS devices and other mobile electronics are smaller, thinner, lighter and more powerful than ever. Wireless Internet connections, RFID and Bluetooth have become essential features of these devices, necessitating highly complex transmission mechanisms.
