The World’s First “Manufactory 4.0” Has Been Opened in Hartford, CT

 

Stanley Black and Decker recently became the first company internationally to open up their brand new “Manufactory 4.0” at Constitution Plaza in Hartford, CT. This 23,000 square-foot center will serve as a state-of-the-art advanced manufacturing center and training center for the company’s international industry 4.0 “smart factory” initiatives. This new facility will also help to highlight Stanley Blacker and Decker’s success with integrating industry 4.0 practices into their company’s policies, such as how they have improved communication between humans and automated technology, used interconnected systems to improve the collaboration between plants and solve problems, and utilize big data analytics to improve productivity and efficiency world-wide. Operated by a team of experts in the field, the facility not only aims to showcase the company’s continued work with integrating technologies and practices of the future into their current manufacturing technologies, but also to provide an interactive space where young professionals and younger children can see what types of career opportunities are available in advanced manufacturing.

 

Based in New Britain, CT, Stanley Blacker and Decker operates and maintains approximately 30 manufacturing facilities across the US, and more than 100 facilities worldwide. Out of these locations, three facilities have been designated as “lighthouse factories”, which have been working to partially implement industry 4.0 techniques into their facilities and into other technologies, such as manufacturing execution systems (MES), artificial intelligence systems, 3-D printing, and virtual reality. Now, with the opening of the new Manufactury 4.0 facility, the company plans to integrate another 25 “lighthouse facilities” into their global base by the end of the 2019 year.

 

The opening of the Manufactory will make Hartford the epicenter of the company’s industry 4.0 efforts. Not only will this help to integrate smart factory 4.0 technologies into Stanley Black and Decker locations world-wide, but it will also help to catalyze Connecticut’s evolution into the leading market for advanced manufacturing in the United States. A Manufactory is described as a training center, that utilizes industry 4.0 technologies such as digital thread, digital twin, IoT, ARVR and big data analytics to help connect manufacturing facilities world-wide and integrate new and innovative industrial technologies into the workforce on a united front.  Through their virtual reality techniques, the center will work to assist other facilities world-wide in adopting leading edge-technologies and ensuring that the global workforce is adequately prepared for the new industry. One of the highlights of this facility is the demo shop floor, where the all the technologies and equipment are part of the facility’s digital thread. These fully specified machines, along with are used to train operators and mechanics around the world.

 

Dr. Bollas and Dr. Thompson with the University of Connecticut UTC Institute of Advanced Systems Engineering attended the Stanley Black & Decker (SB&D) Manufactory Grand Opening last Thursday in Hartford with a contingent of faculty and staff from the University of Connecticut. SB&D’s CEO, Hartford’s Mayor, and Connecticut Governor Lamont all attended and spoke at the opening. This news clip captures Dr. Thompson discussing the capabilities of Infosys technologies with an Infosys representative. The Infosys technology monitors a parts orientation process and determines raw material, process, or machine errors and defects, real-time, with an intuitive, graphical user interface. The machine operator has the ability to determine problems with a better data set and with built-in AI that aids in the diagnosis of errors and faults. This data can then be used to better design the parts, improve the process and machine, or resolve supply chain quality issues.

 

The SB&D Grand Opening was a culmination and celebration of a multiyear effort to launch the Industry 4.0 initiative at SB&D.  The manufactory space’s purpose at this one-of-a-kind facility is to implement new augmented reality, virtual reality, AI, IoT, and Big Data technologies to support its development of digital threads and digital twins and improve product and manufacturing capabilities and efficiencies that coincides with the work being done at UTC IASE. The Institute for Advanced Systems Engineering looks forward to the opportunity to support them in this effort and to partnering with them to help make industry 4.0 a reality.

The CTIN4SPIRE Seminar Series Hosts Dr. Wolf Wadehn

 

On April 18th, Dr. Wolf Wadehn spoke at the weekly seminar series for the CTIN4SPIRE program. Dr. Wadehn is the Director of Engineering at TRUMPF, Inc. in Farmington, CT, where his work focuses on establishing his company’s US subsidiary as a global competence center for remote service tools, machine connectivity, and data analytics. Dr. Wadehn studied mechanical engineering at the University of Munich and Stuttgart and completed his Ph.D. thesis on adaptive structures. In 2005, he started as an engineer for TRUMPF, where he worked on numerical calculations for 5-axis laser machines until he started his management position in 2015.

 

In his talk entitled “Smart Factories: Industry 4.0 in Sheet Metal Manufacturing”, Dr. Wadehn explained that his intention of his presentation was to disprove that manufacturing is “slimy and greasy” and only requires mechanical engineers. TRUMPF has been a family owned business since 1923, has 73 subsidiaries, and is comprised of 13,420 employees. The company specializes in using advanced machining and special laser systems for cutting, punching, bending, welding, marking, and other industrial applications. He described the company’s core competencies, such as innovative practices utilizing laser technologies and prioritizing “speedy” innovation, to segway into current technologies in the industry and what specialized smart factories of the future may look like. He handed out samples of laser cut material to the class, and explained the process of using a laser machine to perform specific tasks, such as cutting a material like the sample, which contained intricate small features. The sheet metal cutting machine will need to operate continuously throughout the process, and if it is not running continuously, manufacturing companies can lose thousands of dollars each day or each week, so uptime is crucial.

 

He finalized the talk by describing how smart factories can be used to maximize efficiency of production and to minimize cost, and outlined the equipment and technologies that can be found in a smart factory. Dr. Wadehn explained seven (7) components of a smart factory: 1. Connectivity and transparency, 2. Full control of equipment, 3. Inventory management, 4. Full transparency on order status, 5. No searching times, 6. Automated transport with AGV, and 7. Remote support through experts. He used these components to illustrate how the current production practices can be improved upon. He also mentioned how smart factories create a smart material flow, which eliminates the possibility of any parts going missing.

 

Dr. Wadehn closed the presentation by showing an example factory of the future and described what a customer’s smart manufacturing project would look like. He explained that smart factories use innovative technologies, such as AGV systems, predictive maintenance, and advanced software to increase the efficiency of manufacturing. In addition, the integrative concepts found in these factories provide jobs for more than just mechanical engineers; this type of work requires an integrative team of engineers and non-engineers from many disciplines to help the manufacturing process run smoothly.

 

The CTIN4SPIRE program will be hosting two more talks this semester on Thursday April 25th  and Thursday May 2nd. To view the CTIN4SPIRE speaker series calendar and to find out more about the series click here.

UConn IASE recognized for their work with Sustainable CT Award Winner

 

 

Members from the UConn Institute for Advanced Systems Engineering (IASE) recently supported the Town of Fairfield’s application for recognition in the Sustainable Connecticut Program that earned them a top-level honor in the program.

 

The Sustainable Fairfield Task Force (SFTF) provides support for projects and initiatives that help Fairfield maintain the growth and health of its environment, ensure a proper and economical use of the town’s natural resources, and promote a high quality of life for all residents. Multiple municipal departments contribute to the SFTF, each of which focus on different aspects of Sustainable CT initiatives. The UConn team was primarily responsible for providing building energy benchmarking technical support to the Fairfield effort.

 

The UConn team was led by Dr. Amy Thompson, an Associate Professor-in-Residence of Systems Engineering at the IASE. Two undergraduate students, Ian Beattie, a senior in Environmental Engineering, and Emma Atkinson, a senior in Biomedical Engineering contributed as well. The UConn students collected building energy information and data from Fairfield and United Illuminating and used the EPA’s Portfolio Manager tool to provide building energy assessments for each of Fairfield’s 22 municipal buildings and 16 school buildings. The building energy benchmarking component was a key component in the Sustainable CT judging process. United Illuminating provided funding to the UConn IASE for faculty and student support of the benchmarking effort and also provided the real-time data exchange system that made the benchmarking possible. “United Illuminating believes that supporting engineering students in this project to learn more about building energy efficiency may encourage them to enter careers in energy engineering. The project allows students to see first-hand real issues and solutions for lowering building energy consumption in municipal and school buildings and the project provides a valuable technical resource to communities like Fairfield,” says Sheri Borrelli, United Illuminating.

 

The Sustainable CT Initiative, which began last October, awards certifications to towns and communities across Connecticut that achieve high standards across a variety of sustainability accomplishments. The program gives awards in three categories based on the amount of points received. The highest ranking is a Gold Certification, the second is the Silver Certification, and the last is the Bronze Certification. The town of Fairfield earned tops honors for the program, being one of only five towns in the state to receive a Silver Certification. In addition, Fairfield also received the highest ranking in the Silver category, deeming the town the “Most Sustainable Town in Connecticut”. Some of the most notable accomplishments that were cited from the Fairfield application were building awareness of the town’s history, assessing potential town-wide impacts of climate change, supporting projects such as recycling, composting, green space preservation, and complete streets policies, and increasing the use of solar energy systems across the town.

 

An awards ceremony took place at the Fairfield Museum and History Center on January 18th, 2019, which celebrated the award and honored everyone who contributed to not only the award, but making Fairfield a sustainable place to live and work. UConn students left the ceremony thinking, “this is a great place to live.”

 

UTC-IASE Faculty Spotlight: Dr. Xu Chen

 

This week’s faculty spotlight is on Professor Xu Chen, who is an assistant professor in the Department of Mechanical Engineering. Dr. Chen received his M.S. and Ph.D. degrees in Mechanical Engineering from the University of California, Berkeley in 2010 and 2013, respectively, and his Bachelor’s degree from Tsinghua University, China in 2008.  He is a recipient of the National Science Foundation CAREER award, the Young Investigator Award and the Best Paper Award from ISCIE / ASME International Symposium on Flexible Automation, the 2017 Best Vibrations Paper Award from the ASME Dynamic Systems and Control Division, the 2017 UConn University Teaching Fellow Award Nominee, and the 2012 Chinese Government Award for Outstanding Students Abroad.

 

Professor Chen is the principle investigator for the Machine, Automation and Control Systems Laboratory (MACS) through the Department of Mechanical Engineering. The overall research goal of his lab is to seek better understanding and engineering of the systematic interplay between data, systems and controls in machines and automation processes. For instance, fast situational awareness and agile response is imperative to advancing system operation in this information age. To reach such capabilities, Prof. Chen’s team exploits approaches to reliably and quickly combine all data from heterogeneous sources in a feedback control system. An example of such is a project conducted from Dr. Chen’s smart manufacturing research called “Model-Based Sparse Information Recovery by Collaborative Sensor Management”. This project provides a novel approach to collect dense information from a group of collaborative sensors at a significantly reduced computation burden and in real time. The result is particularly impactful for applications such as imagining-based automation, where vision data take time to collect and complex elaborations must be performed to extract information from the raw data. More broadly, this work relates to the overarching challenge of making full use of data to infer and respond to fast evolving situations in decentralized environments, and provides a pathway to better integrate multiple data-intensive sources.

 

During the summer of 2018, Dr. Chen and his laboratory team traveled to three flagship conferences in the fields of controls, automation, and 3D printing: The American Control Conference at Milwaukee in June, the International Symposium on Flexible Automation at Kanazawa, Japan in July, and the Annual international Solid Freedom Fabrication at Austin, Texas in August. The three published papers from Prof. Chen’s team discussed smart controls approaches for critically needed quality assurance of additive manufacturing (AM), a nascent manufacturing technology that offers untapped potential in a wide range of products for the energy, aerospace, automotive, healthcare and biomedical industries. In particular, the focused powder bed fusion process is increasingly preferred in applications ranging from advanced jet-engine components to custom-designed medical implants. Prof. Chen’s research looks into the convoluted thermomechanical interactions in the multi-physics multi-scale manufacturing process, and has been generating award-winning, internationally recognized results to enable substantially higher accuracy and greater reproducibility in AM. For instance, the recent paper titled “Synthesis and Analysis of Multirate Repetitive Control for Fractional-Order Periodic Disturbance Rejection in Powder Bed Fusion” was featured in the proceedings of the 2018 International Symposium on Flexible Automation, where this paper written by PhD Student, Dan Wang, and Dr. Chen, won the “Best Paper Award In Theory”.

UTC-IASE Faculty Spotlight: Dr. Ashwin Dani

 

This week’s UTC-IASE faculty spotlight is on Dr. Ashwin Dani, who is an assistant professor in the Department of Electrical and Computer Engineering. He received his B.S in Mechanical Engineering from the University of Pune in India, and then went on to receive a Ph.D in Mechanical and Aerospace Engineering from the University of Florida. He began his career in academia as a post-doctoral research associate at the University of Illinois at Urbana-Champaign in 2011, and then moved to the University of Connecticut in 2013 and currently works as an assistant professor.

 

Dr. Dani is the PI for the Robotics and Controls Lab, which focuses on solving various estimation and control challenges in engineering domains such as robotics, automation, industrial and biomedical applications. His research falls into areas such as (1) Model building from data using machine learning, (2) Human-Robot collaboration and safety issues in manufacturing environments, (2) GPS-denied navigation of unmanned aerial systems and improved autonomy, (4) sensor data fusion, and (5) estimation and control for neuro-prosthesis. He has also done previous work in areas such as estimation and control theory, robotics, autonomous navigation, localization and mapping, and vision-based control.

 

This summer, Dr. Dani attending the American Control Conference in Milwaukee, where a paper titled “Learning Stable Nonlinear Dynamical Systems with External Inputs using Gaussian Mixture Models” was presented by the UTC-IASE Fellow Iman Salehi. Iman Salehi, a UTC-Fellowship graduate student, worked under the counsel of Dr. Dani this summer. Salehi’s project is titled “Physics Informed Machine Learning Project”, which is researching how to develop models for heat exchangers using machine learning that embeds dynamical system properties. The efforts in this project bring a paradigmatic change to how model building using machine learning is looked at to include physical properties of the system. This paper presented a data-driven modeling method with convergence guarantees embedded in machine learning. This paper is closely related to the “Physics-Informed Machine Learning Project”.

 

Professor Dani worked with UTC this summer on a project titled “Physics Informed Machine Learning” and “Wire Harness Assembly using Robots”, with a goal to develop methodologies and architectures for data-driven model learning, containing dynamical system properties coming from physics of the system embedded in machine learning. In terms of research publications, Dr. Dani and his lab worked on extending the conference manuscripts presented over the summer, to journal manuscripts, for projects  “Physics Informed Machine Learning”.

Dr. Abhishek Dutta’s Microcircuit Shows Promise to Improve Biobots

 

UTC IASE faculty member, Dr. Abhishek Dutta, was recently highlighted by the university, in recognition of his work on biological control systems and bio-robotics. Dr. Dutta, who is an assistant professor of Electrical and Computer Engineering, is using his specialization in control systems, design and optimization and cybernetics, to build a hardwired biological insect that can be used to precisely control the insect’s motion.  Since then, the “UConn neuro controller” has been trending in hundreds of news outlets worldwide engaging as many discussions on social media.

The microcircuit is strapped to the roach, and then interfaces with wired micro-electrodes that connect into the antenna lobes. The signal is transmitted through a wireless device in the circuit and a receiver allows for the motion to be controlled through a ground station. The microcircuit sends tiny electrical currents through the wires into the neural tissue in the antenna lobe. Once the brain receives these impulses, it makes the insect believe that there is an obstacle away. Therefore, if an appropriate signal is received by the left antenna lobe, the insect will move to the right and vice-versa.

Professor Dutta is using the Madagascar Hissing Cockroach as the organism under study, where he has built a microcircuit that wires directly into the brain of the roach and uses the circuit as a neuro controller. The circuit incorporates a 9-axis inertial measurement unit that can detect the roach’s six degrees of free motion, its linear and rotational acceleration, as well as its compass heading. Other features that help with the performance of the circuit is a sensor to detect the ambient surrounding temperature, which will help map the correlation between the environmental conditions and the motion of the roach.

Although a couple of similar systems have been developed previously, this microcircuit stands out because it offers a multi-faceted approach for stimulating the nerve tissue, real-time feedback of the insect’s response to the electrical stimuli, and a greater degree of control of the insect’s motion, resulting in a more informed and precise control system. As the microcontroller and built-in potentiometer work in tandem, the operator is able to vary the output voltage, frequency, and cycle of stimuli delivered, which helps to produce a more robust response, while not causing damage to the roach.

This work shows great promise, with the possibility of human applications in the future. Microcircuit and micro-control systems, such as these, are the first step in developing  larger-scale controllers and circuits that can be used in industries like healthcare, automotive, and artificial intelligence. One proposed use is to use this technology to help control motor functions in organisms with spinal cord injury or paraplegic organisms. “Our microcircuit provides a sophisticated system for acquiring real-time data on an insect’s heading and acceleration, which allows us to extrapolate its trajectory,” says Dr. Dutta. “We believe this advanced closed loop, model-based system provides better control for precision maneuvering and overcomes some of the technical limitations currently plaguing today’s micro robots”. Dr. Dutta states that much more research is needed, although the current technology has great promise to lead to a new generation of products with even larger scale applications.
