Careful attention tosafety planning has been required because; these industrial tools present many of the samehazards as conventional machine tools. Thus, engineers working in the areas of robotics musthave a well-structured understanding of robotic systems. Model driven simulation is a valuabletool for helping in this aspect. RoboCell simulation software is one such model driven simulationprogram. Simulation is a powerful tool, but robotics research should be conducted on robots. Inthis paper we provide a brief approach to learning technical aspects of industrial robots throughuse of an educational robot and RoboCell simulation software

Certification tests will then be developed withimplementation planned for fall 2005.Committee membership consisted of K-12 educators, engineering educators, and practicingengineers. The biggest hurdle faced by the committee was reaching a common understanding ofwhat engineering is and is not. The committee agreed that engineering is not the same asmathematics or science, not applied mathematics and science, and not technology. A consensuswas reached to use the engineering method, i.e., synthesis/design, as the basis of the standards.ABET EC2000 accreditation criteria also influence the

A brief description of each of these humancognitive capacities follows: Ability to Use Symbols: By the use of symbols, humans transform immediatevisual experiences into internal cognitive models that in turn serve as guides for theiractions. Through symbolizing, people also ascribe meaning, form and duration to theirpast experiences. Learning Through Observations: Learning can also occur indirectly by observingother people’s behavior and its outcomes. Individuals’ capacity to learn by observationenables them to obtain and accumulate rules for initiating and controlling differentbehavioral patterns without having to

participants havebeen women and minorities, and 65% plan to pursue engineering in college. IntroductionBy 2010, the Department of Labor predicts a shortage of engineers in the U.S. This shortagemay be attributed to a large group of engineers who will be retiring and a lack of freshengineering talent. Less than 15% of all high school graduates in the U.S. have the math andscience background necessary to enter an undergraduate engineering curriculum.1 Only 2% ofhigh school graduates pursue engineering degrees in college, and only 0.5% of women andminority high school graduates pursue engineering degrees in college.2,3 Proceedings of the 2003 ASEE Gulf-Southwest Annual Conference

Managers must take a broader scope ofresponsibilities of their facilities. There is greater requirement of the middle and upper level ofenergy manager to manage a large facility. In addition to the demand for implementation ofenergy conservation, Energy Managers are obligated to develop a future plan that alleviates riskthrough alternate energy sources, financial derivative, and overall management plan. Further,these managers must develop requested proposals, supervise the construction, measurement, andverification of the energy savings.

Over 65% of Infinity graduates planned to study engineering in college, and nearly100% would recommend the program to others. With Infinity’s history of success, the goal is toput it in every high school in Texas by 2005.

Of course, if the teams are to be selected by the instructor, there is thedesire to do it effectively. As noted above, the literature provides little help. Thus thisproject was initiated to determine what is the make-up of effective teams or who are the“good” team players. MethodologyThe plan was to gather as much data as seemed relevant from each student enrolled ineach class in the fall, 2002 semester, to organize the individual student characteristics bythe self-formed groups, to conduct a peer evaluation within each group, to evaluationgroup performance as always at the end of the semester, and then to

While it is true that much of the information was identical, thecourses each had department specific numbering and therefore the graduating department’scourse number would need to appear on a student’s degree plan in order to graduate, requiringstudents to “re-take” freshman courses.Another problem transferring students encounter is the satisfaction of the University’s computerproficiency requirement.

LearnedThe main lesson learned was that it is very difficult to do a complete custom designproject, using the university purchasing system, within only one semester. As a result,we will be looking for projects that can more appropriately be done in two semesters. Aswitch to a two-semester project will probably result in an increase in the price. Also, ourexperience with the scope of the projects will cause us to be a bit more conservativeregarding what we are able to do within a particular time period. We also plan to try toformalize the customer requirements sooner and in greater detail so that disagreementsover scope issues will be less of a problem.

Understanding qualities such as flow velocity and uniformity, as well asturbulence levels, enables a better understanding of the test environment. This leads to betterexperimental planning.

The simplestoption, and perhaps the most costly, would be the purchase of a commercial gas turbine testsystem.
