Mechanical Engineering partners with the WISE program, which receives a Grant to Continue Supporting STEM Education

TechPREP — a STEM program for middle school students on Long Island — has received a $20,000 grant from the Long Island Community Foundation. TechPREP is a collaborative effort that includes Stony Brook University’s Women in Science and Engineering (WISE) program, Department of Technology and Society, Department of Mechanical Engineering, Department of Research Technologies and Innovation, along with local school districts. The grant will provide funding and facilitators for a one-week summer STEM program, which will serve as many as 100 students from high-need school districts.

As part of the TechPREP program, Prof. Anurag Purwar will offer a Robotics Workshop to the middle school girls from the disadvantaged school districts in Long Island.  He says, “the TechPREP program generously funded by the LICF seeks to address the gender imbalance in engineering, and the Women in Engineering Day will introduce students to the art, practice and excitement of doing engineering design and ultimately help them make better career choices.”

Prof. Anurag Purwar from our department recently served as the General Conference Co-Chair for the 2016 ASME International Design Engineering Technical Conferences (IDETC/CIE) held in Charlotte, NC and attended by more than 1400 people. This flagship meeting for the ASME Design Engineering Division and the Computers and Information in Engineering Division consisted of the 11 conferences on topics ranging from Advanced Vehicle Technologies, Design Automation, Design Education, Mechanisms and Robotics, Multibody Systems, Nonlinear Dynamics, Control, Vibrations, Biomedical Devices, Design for Manufacturing and the Life Cycle Conference, and Micro- and Nanosystems. 

Drawing largely from the 970 draft papers submitted, the conference featured 772 archival paper presentations and 74 technical presentations across a wide range of session topics, complemented by plenary and keynote lectures, lively panel discussions, industry sessions, and informational tutorials and workshops addressing a rich spectrum of cutting-edge topics related to design, analysis, computation, and academic/professional success.

Prior to serving as the chair of the ASME IDETC/CIE, he served as the conference chair of the 2015 ASME Mechanisms and Robotics Conference and as the Program Chair of the 2014 Mechanisms and Robotics Conference (MR). He is an elected member of the prestigious ASME Mechanisms and Robotics Committee.  https://www.asme.org/events/idetccie/about/organizing-committee

Prof. Anurag Purwar (PI) and Jeff Ge (Co-PI) win a three-year $440,735 prestigious NSF award for conducting their research on A Computational Framework for Data-Driven Mechanism Design Innovation

Recent trends in democratization of manufacturing capability such do-it-yourself hobby shops, 3D printing technology, as well as low-cost sensors, actuators, and microcontrollers, call for a corresponding democratization of design tools that can help engineers and tinkerers alike to innovate and invent motion generating devices. Motion generation is a fundamental aspect of machines, at the heart of which are kinematic mechanisms that make it possible for motions to be transmitted or transformed. A kinematic mechanism is a collection of moving pieces linked together through kinematic joints such as hinge joints and sliders. Mechanism design innovation involves the selection of an appropriate mechanism type (i.e., the number of moving pieces and joints as well as the pattern of their interconnections) and the determination of key dimensions in the mechanism needed to generate the desired motions. Once a mechanism type is selected, the appropriate dimensions can often be determined by solving a system of polynomial equations. The task of type selection, however, is not so amenable to mathematical treatment, and requires a level of intuition that may take many years to develop and is difficult to pass on. This award supports the development of a set of web-based, data-driven design tools that unify the type and dimensional synthesis for mechanism design innovation. The planned MOOC (massive open online course) will help bring these tools to the masses and help promote interest in science and engineering including high school students and those from under-represented groups. The research team will bring together the diverse fields of reverse engineering, computational shape analysis, and design kinematics to develop a data-driven paradigm for kinematic synthesis of mechanical motion generation devices. The goal is to advance the science of mechanism design and lead to practical and efficient design tools capable of solving highly complex motion generation problems faced by machine designers. Central to this research is the creation of a new computational framework for simultaneous type and dimensional synthesis of various mechanisms.

Stony Brook prof develops lift for seniors

The idea for the product came to Anurag Purwar when his friend, a retired physician, complained of struggling to do what so many younger people take for granted: sitting and standing.

So Purwar, a Stony Brook University mechanical engineering associate professor, designed a device resembling a walker that's equipped with an electric motor to lift seniors from chairs, then ease them back down. Now he is working with Biodex Medical Systems Inc. of Shirley to develop it into a full-blown product.

"There are so many people who need help standing and sitting as they grow older," Purwar said.

The collaboration between the professor and Biodex is part of a growing push on Long Island to commercialize technology from Stony Brook and other research facilities. Officials hope the brainpower of local laboratories will spawn a culture of high-tech start-ups to boost the region's struggling economy.

Purwar and Biodex have $80,000 to develop the invention, primarily from The Research Foundation for SUNY. They plan to target nursing homes, hoping to sell about 500 of the products annually for around $5,000 apiece. They plan to pitch the device as a way to help nurses and other employees avoid back injuries while helping patients out of chairs.

The challenge, industry experts say, will be making the device lighter, cheaper and more versatile than existing products.

"Back injuries are a huge issue, and there are already products out there," said Robert Heppenheimer, chief executive of the Nesconset Center for Nursing & Rehabilitation, who isn't associated with the product. "But if this one is cheaper and easier for nursing homes to use, there could be a market."

The bigger potential, however, could be selling the product for seniors to use in their homes, Heppenheimer said.

Purwar designed the device, called the Mobility Assistant, with help from a student, Thomas Galeotafiore. It's powered by a 12-volt battery, weighs about 30 pounds and is equipped with wheels to function also as a regular walker -- a feature Purwar says sets it apart from other products.

Ed Behan, a Biodex vice president, met Purwar last year at a workshop at Stony Brook for aspiring entrepreneurs. The company, founded in the 1950s as Atomic Products Corp. to develop equipment for researchers at Brookhaven National Laboratory, manufactures a variety of medical devices. Behan hopes to have Purwar's invention on the market within 18 months.

"More and more people want to maintain their independence and mobility," he said. "And this fits that need perfectly."

Stony Brook Team Wins National Award For Technology that Harvests Energy from Railroad Train Vibrations

STONY BROOK, NY, November 15, 2012 – Stony Brook University engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while 
reducing carbon dioxide emissions. The team’s work, “Mechanical Motion  Rectifier (MMR) based Railroad Energy Harvester,” was awarded “Best Application of Energy Harvesting” at the Energy Harvesting and Storage USA 
2012 conference, held in Washington, DC on November 7-8, 2012.The Stony Brook team, led by Professor Lei Zuo and two graduate students  Teng Lin and John Wang from the Department of Mechanical Engineering and 
Advanced Energy Research and Technology Center, developed a new type of  energy harvester that converts the irregular, oscillatory motion of  train-induced rail track vibrations into regular, unidirectional motion, 
in the same way that an electric voltage rectifier converts AC voltage  into DC. Professor Zuo estimates that the invention could save more than $10  million in trackside power supply costs for railroads in New York State 
alone, along with a reduction of 3000 tons per year of CO2 and a half  million dollars of electricity savings.
