Orange Intelligenz: What Is Robotics Accuracy?

The world of robotics is exciting, with new applications emerging. One critical factor in robotic applications is accuracy, which can be misinterpreted in the field. To dive into the topic, host Tyler Kern welcomed KUKA Robotics Senior Staff Engineer Houssaine Waled.

Kicking off the conversation, Waled defined robotic accuracy.

“It’s the ability of a robot to go to a commanded position, which is different from repeatability. A robot may be able to return to the same spot over and over again, but it’s not the precise spot.”

In many cases, robots need to be accurate and master repeatability. Other times, only one attribute is necessary. It all comes down to the application.

A robot straight from the factory without calibration can be repeatable but not accurate. So, what applications require accuracy?

“Medical robotics requires accuracy, as do different machining functions like contours,” Waled said.

Waled also noted that there are two kinds of accuracy—static and dynamic. Again, the type of accuracy links to the robot’s job.

When Waled works with customers in determining what their robotics needs are, there are basic questions that help him recommend the right one.

“First, what does the robot do? We talk about much accuracy they need and if that’s possible. Also, we ask about the environment,” he commented.

Once this team understands the application holistically, they work toward a solution. Find out more about accuracy and repeatability by tuning into the episode.
