The brand new MC600 is designed for dependable cellular 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 cellular manipulators. Its F45.05 Committee on Robotics, Automation, and Autonomous Methods is growing a normal designated as WK92144.
A cellular manipulator is broadly outlined as an autonomous cellular robotic (AMR) base with an hooked up multi-axis robotic arm. The ANSI/RIA R15.08-1-2020 customary defines a classification scheme for industrial cellular robots (IMR), which incorporates cellular manipulators as a category.
The objective of ASTM’s customary is to show the precision of a such a robotic and supply a sequence of quantifiable assessments for measuring the accuracy of the manipulator and cellular base’s actions. The analysis for the rising testing customary relies on a Nationwide Institute of Requirements and Expertise (NIST) paper.
Requirements efforts concentrate on definitions, testing
“We began this requirements effort in 2014 or 2015,” stated 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 car 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 informed The Robotic Report. “NIST had examined noncontinuous efficiency with a number of robots, resembling 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 targeted on AMR testing, with job teams for cellular manipulation, grasp-type finish effectors, and robotic meeting, Aboul-Emein defined. The cellular manipulation group has greater than 30 members.
By supporting foundational assessments for workpiece properties, ASTM needs to assist business create constant documentation of robotic configurations. Aboul-Emein described a configurable check equipment for cellular 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 habits. They could possibly be used to develop simulations of robots and their behaviors, acknowledged Aboul-Emein.
“It undoubtedly has potential, however there are at all times elements lurking in the true world, resembling a dip within the lab ground or the burden of the arm when it’s absolutely stretched out to 1 facet,” he stated. “We’ve been engaged on objects to evaluate cellular manipulators and measure their habits, all primarily based on consensus out of the committee. These requirements live paperwork.”
ASTM introduces testing desk for cellular 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 customary 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 cellular 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 regulate the tabletop to face at 90 levels, tilt to 45 levels, or lay flat at 0 levels. To make the assessments tougher, they will connect a shaker that provides movement and vibrations.
“The desk design can be standardized, and the committee will present directions on how everybody can construct their desk,” stated Prather. “A number of check requirements are deliberate primarily based on the desk. The objective is to have NIST job boards and this new desk be the premise for the way we check new greedy/manipulation/meeting functions for accuracy and repeatability.”
“Additionally, count on 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 you can use requirements and ship them out into the neighborhood with the data on how you can leverage these new check instruments we’re going to maintain launching to make sure new robotic techniques can go them.”
“Our hope is that we see humanoids and cellular manipulators having to point out their outcomes to assist finish customers higher perceive capabilities and guarantee they’re getting the proper system for his or her utility,” Prather stated.
