Instructors:

1. Greg Mansfield, office: Workman 213
2. Kevin Wedeward, office: Workman 221, phone: x5708, e-mail: wedeward@ee.nmt.edu, web-page: www.ee.nmt.edu/~wedeward/

Time/Place: TR 02:00pm-04:00pm in Cramer 203 (for lectures and presentations) and TR 02:00pm-05:00pm in Workman 116/187 (for work on project).

Office Hours: TWR 09:00am-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

Goals: Students 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 and identify RF beacon - Design an outdoor robot capable of navigating a given, unobstructed area to remotely locate a RF beacon that has an identifier encoded via Frequency-shift keying (FSK). Location of the beacon will be computed as longitude and latitude along with a metric of error, and the beacon's identity will be decoded.
