Presentation of process control projects. Project PresentationA Student Mechatronics Project A senior student project that reflects the objective of this course is presented next.This project relates to the design and manufacturing of a microcomputer-controlledrobotics system with force feedback sensors. The intended application of this roboticssystem is to pick up a raw egg from one position and unload the egg at another specifiedlocation for automated egg packaging. The closed-loop robotics system set-up is shown inFig.3 .Following are the major activities involved in the project : (1) Gripper mechanism design and fabrication ; (2) Motor drive system and motion control system development; (3) Interface of the motion drive system to the mechanical

larger outcomes assessmentproject to be communicated through ASEE. The scholarship of teaching asks the question, “What pedagogical procedures must bedeveloped to effectively bridge the teacher’s understanding to the student’s learning?”Unfortunately many people view teaching as routine, something almost anyone can do, a given.But if you stop and reflect on the professors you had as an undergraduate you know this is nottrue. The scholarship of teaching goes beyond the delivery of lecture notes. To be an effectiveteacher one must not only understand the material content, but must also understand the differentways in which students learn and be able to convey enthusiasm about the power behind theknowledge. The ASEE has for decades supported

Thesystem’s sensor suite includes: roller lever limit switches, standard lever limit switches, diffuse-reflective fiber optic cable, thru-beam fiber optic cable, infrared devices, and proximity devices.The Mini Mill is a durable PC controlled CNC milling machine specifically designed for desktopmanufacturing applications. The system uses standard CNC G&M codes that conform to theEIA RS-274D standard NC machine language. The mill has an x-axis travel capability of 10inches, y-axis travel of 5 inches, and z-axis travel of 7 inches. The machine is capable ofsimultaneous three-axis helical, circular, and linear interpolation. It is equipped with pneumaticvise and is capable of

Readers may recognize, possibly after some reflection, that the Outboard Boatproblem may be analyzed via linear programming. This suggests that a linear programming modelbe developed from the data in the case study without human intervention. With this in mind, theauthor developed software that interrogates the data base describing an instantiation of that problem,processes that information, and develops the text describing a linear programming model of theproblem under a given set of assumptions.

Minority women are the leastrepresented in engineering, making up only 4.8% of the 1995-96 freshman class6 and receiving 7only 2.2 percent of the Bachelor's degrees in engineering in 1994 . The underrepresentation ofwomen and minorities in engineering is particularly disturbing when one considers the shiftingdemographics in the workforce: By the year 2000, economic expansion will create up to 18 million new jobs, but the number of young job seekers will decline due to a shift in birth rates.

Analog-to-digital conversion describes how analog in- formation is transformed into a sequence of numbers. The binary number system is introduced. Sampling and quantization effects are illustrated using audio, image and video signals. The Nyquist criterion is explained and aliasing effects are demonstrated by undersampling a selection of popular tunes. Digital-to-analog conversion illustrates how analog information can be generated from a sequence of numbers, using children’s talking books as examples.3. Digital logic.

For example, one design team conducted an exploratory analysis that showed a unit change in MTTR produced an overall design score of 12. After spending an additional ten hours or so on the design experience, they achieved a design score of 13. None of their design alternatives reflected the MTTR change. • Because students did not properly conduct or fully understand the exploratory analysis, they did not have a feel for the maximum design score possible. Because their design grade was some percentage of the maximum design

If an object passes closer than 10” in front of the sensor,enough IR light is reflected back to the receiver to raise its output voltage to a calibratedlevel. The A/D converter on the 68HC11 samples the voltage at 100 Hz, and if thepredetermined voltage is detected, the 68HC11 will interrupt the movement of the robot. The IR transmitter is a simple high-output LED from Radio Shack. The detectoris a photo Darlington pair, also from Radio Shack. These components were chosenbecause they were readily available. The LED is forward biased with 97.4 mA of current.The photo Darlington pair converts the received light to an output current. This current ismeasured

The role of technology in American society isstudied and the implications of technology transfer from developed to developing nations aredebated. As an outcome of the TSEC seminar, students learn to relate technological growth tosocio-economic, cultural, and religious aspects of society and probe into the moral and socialconsequences of technological innovations.

However, it was clear that thestudents in Team four, the control, which models a traditional REU, did not feel theexperience offered any degree of team interaction. While lack of interaction andinterdisciplinary experience is no reflection of the effectiveness of the REU programs,overall, it does suggest that a deliberate team structure must be implemented if teaminteraction is expected to be a result of the experience.Overall, the students reported a fruitful experience whether or not they engaged in teamactivities.

Westrongly feel that these problems are symptomatic of most current engineering curricula, whichfocus on engineering science for three years and typically leave design, ethics, communicationskills, teamwork, meaningful computer use, and other critical skills for the final year.In this mode of engineering education, students are lulled into thinking that engineering isprimarily concerned with substituting numbers into equations, rather than about solvingproblems. Their blind reliance on equations reflects a lack of understanding of the physical andbiological basis for the equations, a deficit for which both they and their professors must sharecredit.

people by altering the myth most of us live by--once we haveinternalized a new myth, we will know how to share resources, not just with other human beingsbut also with other species. What Quinn is outlining is a process of moral imagination:recognizing that one's cultural world view is a myth, trying out another view, and seeing howproblems look from that perspective.But one should not hold the new view dogmatically. Moral imagination is a tool for combatingdogma, for recognizing that there are different ethical perspectives that can be applied to aproblem. The hope is that by exercising moral imagination, practitioners will become reflective,considering alternative views and arriving at decisions that are better than one could developfrom only

Their wide-ranging and sophisticated functionality is reflected in the complexity of their user interfaces. This complexitymakes it difficulty to separate the student’s ability to fundamentally understand the problem vs. their ability tocomprehend the user interface syntax. These applications are designed to solve complicated general engineeringproblems and are not study educational hypotheses.Our experiences suggest that fixed simulations as represented by software such as Maxis’ SimCity [14], while easyto use, do not contribute to learning how to model, although they help
