Time/Place: TR 02:00pm-05:00pm in Workman 109 (for lectures and presentations) and Workman 116/187 (for work on project).

Office Hours: TWR 10:30am-12:00pm

Prerequisites:

1. EE 308 and EE 308L (microcontrollers)
2. EE 321 and EE 321L (analog electronics)
3. EE 333 (electricity and magnetism)
4. EE 341 (signals and linear systems)
5. Declared electrical engineering as a major

Description: A course in design methodology as applied to a particular problem in electrical engineering. For a given project, students will integrate their formal course work with the use of computer-aided tools to design, construct, evaluate, and document a prototype system.

Goals: Students enrolled in EE 382 will

1. work in teams,
2. implement key aspects of a design process,
3. design and build a prototype electronic system,
4. conduct experiments to characterize and verify design,
5. communicate aspects of the design process through oral presentations and written documents, and
6. manage the design process.

Project: Outdoor robot to remotely locate RF beacon (aka Direction Finding Robot) - Design an outdoor robot capable of navigating a given, unobstructed area to remotely locate a 438MHz RF beacon. Location of the beacon will be computed as longitude and latitude along with a circular error probability (CEP).
