Information briefs for the week check out the brand new pattern in manufacturing known as microfactories—the place robots rule, a first-ever, ready-to-use 3D printing cupboard, T-skin security sheathing for cobots and industrial robots, and a do-it-yourself 3D printed cobot for desktop manufacturing.
Microfactories: The place robots rule!
Are microfactories the way forward for manufacturing? There’s a manufacturing facility automation pattern that’s simply starting to take maintain that deviates radically from the usual meeting line, particularly these in auto crops. Korea’s Hyundai has constructed such a very totally different auto plant for its electrical automobile manufacturing (EV) in Singapore.
The Hyundai plant is made up of pods or cells the place 60% of the manufacturing of the Ioniq 5 EV is completed by robots (see video); the remaining 40% is accomplished by human employees alone or in partnership with robots.
The online-net on the subject of workers is that it makes use of solely 100 employees to provide 30,000 automobiles a 12 months. In pod assemblies, robots rule!
Alpesh Patel, VP of Innovation at Hyundai, thinks {that a} microfactory’s cell manufacturing technique might nicely be commonplace in just a few years. Total price discount to fabricate is 50% lower than a standard or absolutely customized automated line. “It is because modules use 70% of the identical parts (body, energy, security, conveyor system).” Plus, growth and meeting time is often 50% lower than a completely automated customized line.
“Within the cells” writes Suvrat Kothari, “robots set up parts of a automotive, earlier than shifting to the subsequent zone. The important thing differentiator is that the cells could be programmed with particular directions, proper from putting in parts for various variants of the identical automotive, or to engaged on a totally totally different mannequin. Conventional meeting traces would wish important retooling for related adaptability.”
The cells are linked collectively by a typical conveyor and feeder system, able to offering excessive quantity, excessive combine manufacturing functionality.
Modular automation can scale up or down simply. “Relying on the complexity of the product or sub-assembly, producers can simply count on to get 3-4k items’ per hour (UPH), or 1 million items a month.”
Prepared-to-use 3D printing robotic
Market want: Prepared-to-use, turn-key system offering an environment friendly, quick, and protected answer for manufacturing steel 3D printed components, 
particularly with chrome steel, nickel, and titanium. To fulfill the necessity, Spain’s Meltio and US-based One Off Robotics partnered for the manufacturing of a self-enclosed 3D printing cupboard.
Meltio is a producer and developer of wire-laser steel 3D printing applied sciences, and One Off Robotics is a builder of robotic arm fabrication programs for additive, subtractive, and hybrid manufacturing processes.
In combining their applied sciences, they declare a first-ever, turn-key answer to offer industries with an environment friendly additive manufacturing work cell named the One Off Robotics Cell. In keeping with Meltio Product Supervisor, Alejandro Nieto, “This new {hardware} system permits the client to obtain a ready-to-use cell for robotic steel 3D printing, eradicating the combination course of and lengthy meeting lead instances.”
With a deposition price of as much as 1 kg an hour, this method produces absolutely dense components which can be mechanically equal or superior to these created from conventional means.
The One Off Robotics Cell seamlessly integrates management of the system, permitting the consumer to simply regulate settings for fast printing. Its 8-axis system simplifies printing of advanced geometries and is configured to work with the Meltio House robotic slicer.
Security pores and skin stops robots immediately
Maintaining employees protected from cobots has at all times been a priority; extra so with cobots than commonplace industrial robots, that are normally segregated from employees by fencing or partitions.
In 2016, FANUC launched contact-sensing cobot security padding which had been polyurethane foam pads utilized to the outside of cobot arms. Stopping time in 2016 was 9 milliseconds.
Practically ten years on, Taiwan-based Touche Options (previously named Mechavision) has not too long ago developed a contact-sensing movie of security materials that’s additionally utilized to the outside of not solely cobot arms but additionally to these of commercial robotic arms. Referred to as T-skin, it has a stopping time of 1 millisecond. Wish to know the way lengthy a millisecond is? Take a look at the video beneath.
Touche Options’ founder and chairman, Camus Su, and basic supervisor, Liu Changhe, are graduates of the Industrial Know-how Analysis Institute (ITRI). Their collaboration in 2017 led to Touche Options, which emphasizes “tactile sensing know-how to set off emergency stops in robots, serving as a vital security measure past visible and lightweight grids.”
The founders declare that T-Pores and skin, was developed primarily based on the ISO commonplace unit of 10 newtons (1kgf) that triggers emergency stops in response to an exterior drive of 1 kilogram, inside 1 millisecond, and is unaffected by both electromagnetic waves or RF.
A main goal of Touche Options is “to outfit conventional industrial robots with collaborative [cobot] capabilities, which has garnered fast recognition from main Japanese robotics corporations (FANUC, Kawasaki, and so forth.).
All of which means that industrial robots can now, with the addition of T-skin, tackle jobs previously meant just for cobots working in and round folks.
DIY 3D printed desktop cobot
Acquired a small-shop enterprise with a number of desktop manufacturing wants? Want a stable academic cobot arm for studying tasks? Wish to market and promote cobots on-line to a worldwide viewers? Introducing the award-winning PAROL6 (Supply Robotics).
Roboticist Petar Crnjak is hoping to carry industrial-style robotic arms to a wider viewers with an open-source 3D-printable six-axis design dubbed the PAROL6 — providing help for a powerful 2.2lbs (1kg) payload.
Crnjak says his “PAROL6 is a high-performance, 3D-printed desktop robotic arm, with a design method just like ” of his creation. “The design method of PAROL6 was to be related “to industrial robots by way of mechanical design, management software program, and usefulness. Management software program, GUI [Graphical User Interface], and PAROL6’s STL recordsdata are open supply.” Apart from a pneumatic gripper, every axis is pushed by a stepper motor, with no less than just a few of those axes being pushed by way of a steel planetary gearbox for further precision and torque.
Relying on ones’ stage of experience, PAROL 6, with entry to a 3D printer and on-line design specs (free), it may be a DIY venture; it additionally is available in equipment type; or bought able to go straight out of the field for $3.200 (3,000 euros).
“By pairing industrial mechanical design with state-of-the-art software program and electronics, the PAROL6 robotic can obtain clean motions, excessive speeds, and excessive repeatability. PAROL6 is constructed with training, analysis, and small automation in thoughts!”
