New software allows industrial robots to achieve touch sensitivity and precision close to human hands

Eureka Robotics, a tech spin-off from Nanyang Technological College, Singapore (NTU Singapore), has developed a know-how, referred to as Dynamis, that makes industrial robots nimbler and virtually as delicate as human arms, capable of manipulate tiny glass lenses, electronics elements, or engine gears which can be simply millimeters in dimension with out damaging them.

This proprietary power suggestions know-how developed by NTU scientists was beforehand demonstrated by the Ikea Bot which assembled an Ikea chair in simply 20 minutes. The breakthrough was first printed in Science in 2018 and went viral on the web when it might match the dexterity of human arms in assembling furnishings.

NTU Affiliate Professor Pham Quang Cuong, Co-founder of Eureka Robotics, stated they’ve since upgraded the software program know-how, which will likely be made out there for numerous industrial robots worldwide by Denso Wave, a market chief in industrial robots, which is a part of the Toyota Group.

Shoppers buying the newest robots bought by Denso Wave can have an choice to incorporate this new know-how as a part of the power controller, which reads the power detected by a power sensor on the robotic’s wrist and applies power accordingly: Apply too little power and the objects is probably not assembled appropriately whereas making use of an excessive amount of power might injury the objects.

Mastering contact sensitivity and dexterity like human arms has all the time been the holy grail for roboticists, says Assoc Prof Pham, because the programming of the power controller is extraordinarily sophisticated, requiring lengthy hours to excellent the grip only for a particular activity.

“Right now, Dynamis has made it straightforward for anybody to program touch-sensitive duties which can be often completed by people, similar to meeting, positive manipulation, sharpening or sanding,” explains Assoc Prof Pham, who can also be the deputy director of the Robotics Analysis Centre at NTU’s Faculty of Mechanical and Aerospace Engineering.

“These duties all share a standard attribute: the flexibility to keep up constant contact with a floor. If our human arms are disadvantaged of our contact sensitivity, similar to when sporting a thick glove, we’d discover it very onerous to place tiny Lego blocks collectively, a lot much less assemble the tiny elements of a automotive engine or of a digital camera utilized in our cell phones.”

Hiroyasu Baba, FA/Robotics Enterprise Unit Product Planning Division, Supervisor of Denso Wave, stated: “Because of its excessive primary efficiency and openness, DENSO robots are the popular alternative by firms and universities with superior initiatives within the area of robotics. NTU Singapore and Eureka Robotics have additionally been utilizing DENSO robots because of this.

“Due to this relationship, joint improvement started naturally, and we had been capable of launch this product easily. The know-how, which will likely be put in in DENSO robots, is a know-how for power suggestions, which is changing into increasingly more essential within the sensible use of robotics. Due to the event capabilities of Eureka Robotics, the system is superior, but straightforward to make use of and light-weight sufficient to be built-in into our customary robotic controllers.”

How the brand new software program works

Often called Drive Sensor Sturdy Compliance Management, the brand new software program powered by Dynamis requires solely a single parameter to be set—which is stiffness of the contact, whether or not it’s mushy, medium, or onerous.

Regardless of its easy set-up, it has been proven to out-perform typical robotic controllers which required an infinite quantity of experience and time to fine-tune.

Dynamis is a fancy synthetic intelligence (AI) algorithm developed by Assoc Prof Pham and his former Ph.D. scholar, now Co-founder and CTO of Eureka Robotics, Dr. Hung Pham.

This spine know-how was additional improved and was first deployed in Eureka’s custom-built robots, similar to Archimedes, which might deal with fragile optical lenses and mirrors with human-like dexterity, now utilized by a number of firms worldwide.

Present robots available in the market have both excessive accuracy however low agility (the place robots carry out the identical actions repeatedly similar to in a automotive manufacturing facility), or low accuracy however excessive agility (similar to robots dealing with packages of various sizes in logistics).

By deploying this know-how, robotics engineers can now imbue robots with each Excessive Accuracy and Excessive Agility (HAHA) on a big scale, paving the way in which for industrial functions that had been beforehand very tough or inconceivable to implement, similar to dealing with and meeting of delicate, fragile objects similar to optical lenses, electronics elements, or engine gears.

To be geared up with the Drive Sensor Sturdy Compliance Management functionality, the big variety of robots already operating on Denso Wave’s RC8 controllers will solely be required to carry out a easy software program replace from December 2021 onwards, whereas newly shipped RC8 controllers will come filled with the software program out there for activation.
