The brand new MC600 is designed for dependable cell manipulation, says MiR. Supply: Cellular Industrial Robots
Whereas humanoid robots are taking their first steps into industrial functions, ASTM Worldwide is engaged on requirements for cell manipulators. Its F45.05 Committee on Robotics, Automation, and Autonomous Techniques is growing a typical designated as WK92144.
A cell manipulator is broadly outlined as an autonomous cell robotic (AMR) base with an hooked up multi-axis robotic arm. The ANSI/RIA R15.08-1-2020 normal defines a classification scheme for industrial cell robots (IMR), which incorporates cell manipulators as a category.
The aim of ASTM’s normal is to reveal the precision of a such a robotic and supply a collection of quantifiable exams for measuring the accuracy of the manipulator and cell base’s actions. The analysis for the rising testing normal is predicated on a Nationwide Institute of Requirements and Know-how (NIST) paper.
Requirements efforts concentrate on 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 wanted 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, similar to 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 activity 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 exams for workpiece properties, ASTM needs to assist business 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.
Nonetheless, the brand new requirements wouldn’t apply to finish effectors, payloads, or fleet conduct. They may very well be used to develop simulations of robots and their behaviors, acknowledged Aboul-Emein.
“It undoubtedly has potential, however there are at all times components lurking in the actual world, similar to a dip within the lab flooring or the load of the arm when it’s absolutely stretched out to 1 facet,” he mentioned. “We’ve been engaged on objects to evaluate cell manipulators and measure their conduct, all based mostly on consensus out of the committee. These requirements live paperwork.”
ASTM introduces testing desk for cell manipulators
The Robotic Report additionally reached out to Aaron Prather, director of the Robotics and Autonomous Techniques Program at ASTM Worldwide, for a extra element on the WK92144 normal and the place it’s headed.
The group‘s F45 committee is introducing a brand new testing desk, a device 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 embrace 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 exams tougher, they’ll connect a shaker that provides movement and vibrations.
“The desk design might 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 aim is to have NIST activity boards and this new desk be the premise for the way we take a look at new greedy/manipulation/meeting functions for accuracy and repeatability.”
“Additionally, anticipate to see our new Pupil Competitors Challenges to make use of the boards and desk,” he added. “It will assist get college students concerned in how one can use requirements and ship them out into the neighborhood with the data on how one can leverage these new take a look at instruments we’re going to preserve launching to make sure new robotic techniques can go 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 best system for his or her utility,” Prather mentioned.
