Mechatronics Education At Kettering University: Development Of Learning- Specific Hardware And Software, Jeffrey Hargrove, Theodore J. Stokes
Mechatronics Education At Kettering University: Development Of Learning- Specific Hardware And Software, Jeffrey Hargrove, Theodore J. Stokes
Jeffrey Hargrove
A series of learning-specific electronic circuit boards and associated software has been developed to support mechatronics education in the Mechanical Engineering Department at Kettering University. The boards are designed to interface to the Toshiba TLCS-900H Microprocessor Trainer and Evaluation Board. The purpose of these boards is to provide mechanical engineering students of mechatronics with robust hardware that readily permits interfacing of sensors and actuators to microcontrollers used in mechatronic applications. Further, the boards feature signal conditioning circuits for use in conjunction with sensors, and driver circuits for operating high-current actuating devices. Supporting software has been written to permit ready use …
Development And Implementation Of Mechatronics Education At Kettering University, Jeffrey Hargrove
Development And Implementation Of Mechatronics Education At Kettering University, Jeffrey Hargrove
Jeffrey Hargrove
The Mechanical Engineering Department at Kettering University has completed development of a significant new component of education in mechatronics. The work began in the fall of 1997 as the principal part of an award for “Instrumentation and Laboratory Improvement” by the Division of Undergraduate Education of the National Science Foundation. It has culminated with the successful implementation of two undergraduate courses in mechatronics, two mechatronics laboratories and a website to support the educational endeavors of the mechatronics students. As will be described in this paper, the first course and its laboratory exercises are designed specifically to provide the students with …
Energy Harvesting From Atmospheric Variations - Theory And Test, John Wagner, Gibran Ali, David Moline, Todd Schweisinger
Energy Harvesting From Atmospheric Variations - Theory And Test, John Wagner, Gibran Ali, David Moline, Todd Schweisinger
John Wagner
The last two decades have offered a dramatic rise in the use of digital technologies such as wireless sensor networks that require small isolated power supplies. Energy harvesting, a method to gather energy from ambient sources including sunlight, vibrations, heat, etc., has provided some success in powering these systems. One of the unexplored areas of energy harvesting is the use of atmospheric temperature variations to obtain usable energy. This paper investigates an innovative device to extract energy from atmospheric variations using ethyl chloride filled mechanical bellows. The apparatus consists of a bellows filled with ethyl chloride working against a spring …

A Proposed Learner-Centered Mechatronics Engineering Instructional Program, Patrick N. Currier, Richard Goff, Janis Terpenny
Patrick N. Currier
This paper examines the need and requirements for a mechatronics degree program. The results of a survey of the few existing programs in this field are provided. Then, using a case study example for Virginia Tech, a proposed mechatronics curriculum based on a learner-centered paradigm is described. The curriculum combines existing courses in mechanical, electrical, and computer engineering with new, hands-on courses to provide students with a chance to practice and explore the subject matter in ways consistent with the demands of both industry and accreditation. This program, if implemented, could provide a university with a unique offering to attract …
Nanoindentation And Micro-Mechanical Fracture Toughness Of Electrodeposited Nanocrystalline Ni-W Alloy Films
A.S. Md Abdul Haseeb
Nanocrystalline nickel-tungsten alloys have great potential in the fabrication of components for microelectromechanical systems. Here the fracture toughness of Ni-12.7 at.%W alloy micro-cantilever beams was investigated. Micro-cantilevers were fabricated by UV lithography and electrodeposition and notched by focused ion beam machining. Load was applied using a nanoindenter and fracture toughness was calculated from the fracture load. Fracture toughness of the Ni-12.7 at.%W was in the range of 1.49-5.14 MPa √m. This is higher than the fracture toughness of Si (another important microelectromechanical systems material), but considerably lower than that of electrodeposited nickel and other nickel based alloys. © 2012 Elsevier …
