Jaipur Foot Design Teams In India for Spring Break

During the Spring Break 2012, Dr. Nina Mahmoudian and Dr. Mo Rastgaar and two Mechanical Engineering Senior Design Teams are in Jaipur, India. Below is a group picture of them in City Royal Palace. They are going to visit hospital and see Dr. Jain also on the trip.

The Jaipur foot was developed to provide amputees with a simple, practical, and low cost prosthetic, that is compatible with an active and culturally-appropriate lifestyle. During the 2011-2012 school year, a design team made improvements to the Jaipur foot to reduce weight and standardize the manufacturing process and materials used. A major problem now is incompatibility of materials with the rubber vulcanization process used in manufacturing. This must be optimized while maintaining the affordability and functionality of the foot. Team 7, consisting of Reid Barber, Stephanie Boomgaard, Ben Cottrill, Miriam Paquet, and Kevin Peterson, is traveling to India to meet Dr. Anil Jain of the Dr. P.K. Sethi Rehabilitation and Jaipur Limb Training Center. The main goal of the trip is to gain a better understanding of the process used in India to fabricate the Jaipur foot and to communicate the current status of the project to Dr. Jain. Also, several prototypes will be delivered, with the hope of seeing them demonstrated by amputee patients. The team will return to Michigan Tech at the end of Spring Break and will incorporate feedback to finish improving the design.

Ruth Fisher, James Hartel, Bobby Pizzey, David Weyland are members of Senior Capstone Design Team 8. This team is redesigning and evaluating a cost optimized prosthetic knee joint created by a previous senior design team. The joint must be manufactured in India with local materials and be affordable for the hospital and patients. Current solutions to knee replacement are expensive or ineffective. The team has worked to develop a design that is lightweight, low-cost, and easy to use. The design incorporates a 3-bar linkage system between the upper and lower frames of the device as well as an adjustable damping pad to provide a variable resistance of the swing of the knee which can be tailored to each patient.

Abstract: “The Rise of Open-Source 3-D Printing (Or How We Can Make Everyone a Mechanical Engineer)”

The benefits of this economy of scale have driven a historical trend towards large-scale manufacturing in low-labor cost countries (e.g. China), especially for the now ubiquitous inexpensive plastic products. However, advances in rapid prototyping with 3-D printing have challenged this cost savings paradigm. With the recent development of low-cost, open-source and self-replicating 3-D printers there is now a technically viable form of distributed manufacturing of many plastic products. The costs of the products are 10-100X less than commercial products and can be ultra-customized. In addition, using distributed open-source 3-D printing for manufacturing eliminates non-productive intellectual monopoly rents and associated encumbering overheads, almost all subtractive waste, allows for lower fill products, and cuts most embodied energy transportation, distribution and packaging-related pollution. This indicates that 3-D printing will not simply be a fad, but a fundamentally new way of providing goods to the world’s population via a transition to local (e.g. U.S. or even U.P.) manufacturing. These properties are already attractive for a large percentage of the population and in the last few years the number of 3-D printer operators has grown rapidly, essentially democratizing mechanical engineering. However, this ‘maker’ movement is primarily made up of amateur DIY engineers and thus there exists an enormous opportunity for traditional engineers to help accelerate the technical progress. This seminar will summarize the state-of-the-art of open-source 3-D printers, the Michigan Tech Open Sustainability Research Group’s work on distributed manufacturing, and conclude with an invitation to participate in what the Economist calls the “next industrial revolution”.

Abstract: COOPERATIVE PAYLOAD TRANSPORT BY ROBOT COLLECTIVES

Cooperative material-handling by a fleet of decentralized manipulation agents has many applications ranging from hazardous waste removal, material handling on the shop floor, to robot work crews for planetary colonization. Our long-term goal is the development of a theoretical and operational framework to model, analyze, implement and validate cooperative payload transport capabilities in such distributed robot collectives.

Our particular focus is on creation, control and active reconfiguration of marching formations of wheeled mobile robots for cooperative payload transportation tasks. The selection of the underlying physical/informational infrastructure, system architecture, and mechanisms of cooperation creates many alternatives. A systematic framework is therefore critical for evaluation/selection of suitable implementations with quantifiable cooperative-performance benefits and forms the focus of our research activities. In particular, we will present our efforts to develop methodologies for design and optimization of formations for apriori known tasks, adaptation of formations for changing tasks and scalable schemes for control under the common theoretical but computationally tractable framework.

Time permitting, I will also provide a brief overview of the many other related research initiatives ranging from: (a) uneven terrain locomotion systems; (b) human-computer interfaces for mediated teleoperation; (c) haptic user-interface design and (d) quantitative surgical skill assessment.

Topic: Turbulent Jet Ignition: An efficient, clean combustion concept for the future?

In order to meet future global emissions goals, in the short to medium term it will be necessary to continue to improve the fuel consumption of the spark ignited gasoline engine. Gasoline engine downsizing is the dominant technology being implemented in the US and globally. In addition technologies such as variable valvetrains and stratified lean combustion have been implemented by some manufacturers. This presentation considers the application of a homogenous ultra lean combustion system to current and future engine technologies. The ultra lean combustion system is achieved via a high energy Turbulent Jet Ignition system. Turbulent Jet Ignition is an advanced spark initiated prechamber combustion system. The ultra lean combustion system has been shown to achieve high thermal efficiencies and low NOx emissions. Furthermore the improved knock resistance of the system allows, due to the distributed ignition sites, improvements in the compression ratio or a synergy with boosted applications.
