Chris Savoia is regional head of UR+, Americas, at Universal Robots. He answered some pertinent questions about robotic integration.
As industrial robot installations continue to rise, they continue to be integrated into work cells for palletizing, machine tending, welding and other industrial applications. What innovative or efficient robot-integration applications have you seen or been involved with?
Chris Savoia, regional head of UR+, Americas, Universal Robots: An example of this is with Righthand Robotics, which has an incredible end effector that looks a bit like it is from the movie “Alien.” It has three grasping claws and a suction cup that extends to grab packaged goods from bins, performing millions and millions of picks mainly within the logistics industry. Another example is Translas, who manufactures a welding torch that embeds fume extraction at the tip without comprising weld puddle dynamics or quality (Figure 1). Another recent application is from Versabuilt, which has a patented system that cuts down retooling time for CNC mill machine-tending automation applications. It doubles down as the cobot fingertips can also be the work holding in the machine tool, meaning you cut design in half when changing work orders.
What have been the biggest improvements to robot integration and interoperability with other robots or components in work cells in the past five years?
Chris Savoia, regional head of UR+, Americas, Universal Robots: The robot operating system (ROS) has been a great boon for the industry. Admittedly, ROS is oftentimes more complex and requires more experienced programming skills than is ideal, since it requires the use of a Linux terminal. But ROS has allowed very sophisticated robot systems to be deployed without needing a Ph.D. in robotics, especially since ROS2 has launched, which fixes a lot of the architectural problems of ROS1. Universal Robots maintains an active ROS2 driver that can be used by startups, researchers and other developers to build reliable, innovative products from our platform.
Can you explain how software or open-source control architectures have changed robotic integration?
Chris Savoia, regional head of UR+, Americas, Universal Robots: Open-sourced architectures are not embraced by everyone in the community. Many traditional industrial robots manufactured have very hidden and proprietary systems that stifle innovation. Other more modern robot systems, while still patented and reliable, are built off open-source ideals. Most important is the enablement of the free flow of information. Companies that publish information in developer communities foster innovation, which ultimately leads to a larger general adoption of robots by society.
As manufacturers and warehouses/distribution centers push toward autonomous operations, what is the benefit of collaborative robots (cobots) and their ability to work alongside humans?
Chris Savoia, regional head of UR+, Americas, Universal Robots: Universal Robots is good at human-scale automation, especially for tasks that take about the same physical space and run at about the same rate as a human operator. Along the same lines, the cobots tend to fit better alongside human operators, without as much extensive re-engineering of the workspace. Oftentimes, cobot work cells can even be set up to have the cobot be removable and easily wheeled away so a human can step in to retool machines and set up new jobs. Safety is an important factor here; new innovations in reliably sensing humans present in the work cell means cobots can get closer to human and still have a high safety performance level and thus a solid risk assessment.
When will robotics technology become user-friendly enough that integration, installation, and operation is plug-and-play and no longer requires extensive engineering?
Chris Savoia, regional head of UR+, Americas, Universal Robots: This depends on the task the cobot is doing. We currently see in the welding industry that it is possible for operators—the actual welders doing the current task manually—to take a cobot and teach it how to do things, without the need for an automation or a manufacturing engineer to weigh in. This means that collaborative robots are already user-friendly enough, so that the teaching of the task can be put directly into the hands of the domain expert doing the actual work on the floor.
What future innovations will impact the integration of robotics technology in work cells and with other industrial machinery?
Chris Savoia, regional head of UR+, Americas, Universal Robots: Looking further out, generative artificial intelligence (AI) and the use of large language models (LLMs) should push collaborative robotics to be even easier to use then they are now. Cobots will be more natural with tasking in their environments. Currently, it is often necessary for humans to put themselves in the cobots’ shoes and think about how a cobot should be programmed for a certain task. With generative AI, humans will be able to talk to cobots normally and have the them understand the subtle context and intent behind simple commands.
