Innovations in machine robot coordination enable automated motion control for machine builders and give higher quality manufacturing with greater productivity for end users.
FREMONT, CA: The manufacturing sector witnessed dynamic shifts, especially when the pandemic demanded automation for factories restarting with lesser staff. Today there is a new normal from the great resignation where many workers are simply not returning to work. Robots and general automation is the key to meeting shrinking labour demands and maintaining production lines moving. In addition, end-users continue to discover how robotic and automated systems increase manufacturing productivity and quality, driving further innovation in the industry.

With robotics uses gaining traction, a variety of robot types is increasingly emerging. For repetitive tasks involving human operators, now there are collaborative robots (cobots) on the rise. XYZ gantry systems powered by a motion controller remain popular for pick-and-place operations and product transport as they are accurate, reliable, and cost-effective. There is also an increased demand for selective compliance assembly robot arms (SCARA) for lighter-load applications. They are fast and highly accurate suited to tasks like pharmaceutical packaging. Moreover, they are popular for machine integrations as they are small and easy to program.
Implying a single-machine controller with robot kinematic control built-in eliminated the need for a separate controller for a robot or a series of robots. This integration puts robot and machine functions into a single development environment. This makes machines and robots faster to program for the OEM while also taking away hand-shaking problems. End-users gain more reliable and productive machines and robots.
The increased demand for robotics encompasses the wider motion technology realm, the continuing trend is for higher-performance motion coordination where faster and more accurate control of independent servo or stepper motor axes is demanded. This also includes faster update rates from motion controllers and servo drives based on the EtherCAT digital communications protocol. This refers to higher axis counts, over 100 axes in some cases but the greater speed and accuracy coordination down to just three axes are equally important for applications like 3D printing.
Machine build OEMs continue to look for higher performance as well as want a quicker development time, providing them a faster time to market. This harnessed the trend to more capable development environments facilitating the set-up of all required automated devices rather than switching between various programming software. For machines, motion, and robotic functionality together, such environments are easy to program. Advances in this software kind observed expanded use of features, including virtualisation accelerating testing by creating a virtual model of the mechanical world.
These innovations are interesting as they enable the proliferation of automated motion control to a wide range of machine builders and no longer need the same level of specialised programming skills. Moreover, for end-customers, it offers higher quality manufacturing with greater productivity.
