Machine vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance in industry.

Automate Showcases Future of Industrial Robotics, And It’s Remarkable

Attending the recent Automate Show in Chicago was an extraordinary experience that allowed me and more than 20,000 other attendees an opportunity to peer into the future of industrial robotics. Being part of a company that is at the forefront of the industrial robotics and manufacturing automation industries still provides only one perspective, and Automate brought together leaders from all corners of the industry, such as Fanuc, ABB, Kuka, Keyence and Cognex, to showcase advances and share insights. The range of technologies on display that were designed to enhance processes, improve product quality and lower manufacturing costs was astonishing. I walked away from the show with a deeper sense of awareness of two notions: the rise of robots is upon us, and machine vision provides robots with the artificial intelligence that will forge the future of robotics in our increasingly globalized society.

The Rise of Robots

As many in automation are aware, robots are becoming an increasingly popular answer to completing dangerous or repetitive tasks: grinding, deburring, bin-picking, part inspections, etc. Several manufacturers and esteemed integrators assembled elaborate booths displaying various robot capabilities, many currently in use and others as possible future applications. This alone is indicative of the rise of robots, but it is only the beginning. The leading robot manufacturers all appear to be focused on making robots simpler to program/configure and easier to integrate with technologies that create incredible functionality. The result: collaborative robots.

The show floor featured a number of collaborative robots performing a wide variety of tasks from part handling to packaging, some even bagged candy to hand out or served ice cream in a cone. Using various sensing technologies, the applications for collaborative robots to work with human counterparts are infinite. Long gone seem to be the days of robots in hard guarding and being tucked away in the corner, wrapped in ominous metal fencing. Today’s robots are becoming more flexible in their range of applications, friendly in their interface, and free to be placed anywhere on the manufacturing floor.

Forging the Future

When combined with the interconnectivity of the Industrial Internet of Things (IIoT) and other smart tools such as mobile analytics, machines equipped with technologies like 3D embedded vision, multispectral and hyperspectral imaging, and deep learning will possess a primitive form of artificial intelligence that allows greater flexibility in application and the ability to actively learn processes without programming.

For example, Cognex and Keyence both have solutions that can compare 8-10 different part characteristics in a fraction of a second. These are designed to be mounted on the end of a robot so you have a complete solution that is capable of part picking and inspection. Part picking and part inspection are tasks that are often hard to fill and results can vary widely as operators tire throughout long shifts.

In another instance, Fanuc is working on developing the ability to configure a robot through learning instead of programming, specifically the capability to give a robot a task, like picking objects out of a bin and putting them into another container. In this scenario, once the robot it is configured it will spend some amount of time figuring out how to complete the task via trial and error, and within a short time the robot will have mastered the task as well as if it had been programmed by an engineer. It seems apparent that as we continue to combine advancing vision technologies with low cost, power processing abilities the future is endless as to what can be accomplished.

Although the next Automate isn’t until April of 2019, I highly recommend that you get this event on your calendar early and plan to attend. The Automate show attracts more than 20,000 visitors, all looking for new ways to enhance their manufacturing processes, lower production costs, and increase their competitive edges.

Why It’s Time to Consider Using Vision Technology

coffee_robot_3D_modelBecause the use of vision technologies on the plant floor can give you a competitive advantage, here are the key issues to consider when looking for the right vision system.

How viable is vision technology on the plant floor? On the surface, when you look at the technology and the capabilities it seems like vision should be as common as the programmable logic controller (PLC) and the human-machine interface (HMI). If you think about the technology and its ability to “see” the environment and make decisions based on what it sees, the applications are boundless. Despite its clear advantages, the use of vision technology on the plant floor is not as commonplace as most people would imagine. Why is that?

I believe the main reasons are: 1.) The supporting technology behind the camera; and 2.) Camera installations are often viewed as being not very robust. Continue Reading →

Adding Senses to Robots Multiplies Manufacturing Value

Advancing technologies have given robots the ability to adapt to the environment around them, greatly increasing their value in production applications in manufacturing.

Watching a robot in action is a pretty cool thing. A six-axis robot can perform moves that are as good, or better, than the human arm, and it can do it fast! We regularly wow students on facility tours who get to see our robot demos in action, zipping from one position to another. I imagine this is the case for automation professionals as well. When touring a manufacturing facility and catch a glimpse of a robot in operation, I eagerly await the opportunity to stand in front of it and watch it do its thing. Maybe this is just my reaction. Am I the only robo-geek out there or do you feel the same?

Unfortunately, more often than not, I am let down by what the robot is actually doing: the same thing over and over, following the same path at the same speed. Beyond the initial wow factor generated by a lot of motion and maybe an innovative end-effector (end-of-arm tool), robots are not really doing anything very cool or providing the value they could be if they were to leverage advancing technology.
