The brand new MC600 is designed for dependable cell manipulation, says MiR. Supply: Cell Industrial Robots
Whereas humanoid robots are taking their first steps into industrial purposes, ASTM Worldwide is engaged on requirements for cell manipulators. Its F45.05 Committee on Robotics, Automation, and Autonomous Methods is growing a typical designated as WK92144.
A cell manipulator is broadly outlined as an autonomous cell robotic (AMR) base with an connected multi-axis robotic arm. The ANSI/RIA R15.08-1-2020 commonplace defines a classification scheme for industrial cell robots (IMR), which incorporates cell manipulators as a category.
The objective of ASTM’s commonplace is to display the precision of a such a robotic and supply a collection of quantifiable checks for measuring the accuracy of the manipulator and cell base’s actions. The analysis for the rising testing commonplace relies on a Nationwide Institute of Requirements and Know-how (NIST) paper.
Requirements efforts deal with definitions, testing
“We began this requirements effort in 2014 or 2015,” mentioned Omar Aboul-Enein, co-author of the NIST paper and an F45 committee member. “In lots of instances, there’s noncontinuous efficiency. For instance, the arm and automobile don’t transfer concurrently for machine tending or meeting duties. We would have liked terminology for discrete pose-constrained duties.”
In 2022, ASTM Worldwide expanded its scope to incorporate robotics and automation, he instructed The Robotic Report. “NIST had examined noncontinuous efficiency with a number of robots, reminiscent of AGVs [automated guided vehicles] after which experimented with steady techniques for large-scale manufacturing, like for plane wings, ship bows, and wind turbine blades.”
With R15.08, ASTM has centered on AMR testing, with process teams for cell manipulation, grasp-type finish effectors, and robotic meeting, Aboul-Emein defined. The cell manipulation group has greater than 30 members.
By supporting foundational checks for workpiece properties, ASTM desires to assist trade create constant documentation of robotic configurations. Aboul-Emein described a configurable take a look at equipment for cell manipulation that makes use of low-cost elements and is designed to be simple to breed and permit for in-situ testing.
Nevertheless, the brand new requirements wouldn’t apply to finish effectors, payloads, or fleet habits. They may very well be used to develop simulations of robots and their behaviors, acknowledged Aboul-Emein.
“It undoubtedly has potential, however there are all the time elements lurking in the actual world, reminiscent of a dip within the lab ground or the load of the arm when it’s totally stretched out to 1 aspect,” he mentioned. “We’ve been engaged on gadgets to evaluate cell manipulators and measure their habits, all based mostly on consensus out of the committee. These requirements reside paperwork.”
ASTM introduces testing desk for cell manipulators
The Robotic Report additionally reached out to Aaron Prather, director of the Robotics and Autonomous Methods Program at ASTM Worldwide, for a extra element on the WK92144 commonplace and the place it’s headed.
The group‘s F45 committee is introducing a brand new testing desk, a instrument that helps present the precision of a cell manipulator, linking its arm and base actions. The robotic should attempt to maneuver across the desk whereas its arm performs duties on the floor. These duties embody monitoring an S-shaped black space for welding or gluing and inserting pegs.

Operators can alter the tabletop to face at 90 levels, tilt to 45 levels, or lay flat at 0 levels. To make the checks more difficult, they’ll connect a shaker that provides movement and vibrations.
“The desk design will likely be standardized, and the committee will present directions on how everybody can construct their desk,” mentioned Prather. “A number of take a look at requirements are deliberate based mostly on the desk. The objective is to have NIST process boards and this new desk be the idea for a way we take a look at new greedy/manipulation/meeting purposes for accuracy and repeatability.”
“Additionally, anticipate to see our new Scholar Competitors Challenges to make use of the boards and desk,” he added. “This can assist get college students concerned in methods to use requirements and ship them out into the group with the data on methods to leverage these new take a look at instruments we’re going to preserve launching to make sure new robotic techniques can move them.”
“Our hope is that we see humanoids and cell manipulators having to indicate their outcomes to assist finish customers higher perceive capabilities and guarantee they’re getting the precise system for his or her utility,” Prather mentioned.
