  1. Development of a Multidisciplinary Curriculum for Intelligent Systems Dimitris C. Lagoudas, Jeffery E. Froyd Othon K. Rediniotis Thomas W. Strganac John L. Valasek John D. Whitcomb Rita M. Caso

  2. Combined Research Curriculum Development http://smart.tamu.edu/CRCD

  3. Combined Research and Curriculum Development Project • Develop new curriculum track with a certificate on Intelligent Systems. • Track will consist of new courses as well as modifications of existing courses. • Impact will culminate in a year long senior design course dealing with the design of intelligent systems.

Department Course Level Course# (credit) I Students Enrolled Required/Elective Brief Description of Course Innovation Systems Engineering Junior/Senior SYEN 489 (3) 20 Required Intelligent Structures and Systems Systems Engineering Junior/Senior SYEN 489 (3) 20 Required Fluid-Structure-Control Interaction Aerospace Engineering Junior AERO 304 (4) 20 Elective Structural Analysis of Active Systems Mechanics and Materials Senior MEMA 471 (3) Whitcomb 20 Elective Analysis and Design of Smart Composite Materials Aerospace Engineering Senior AERO 401 (3) Valasek 20 Elective Aerospace Vehicle Design I Aerospace Engineering Senior AERO 402 (2) Valasek 20 Elective Aerospace Vehicle Design II Mechanical Engineering Senior MEEN 411 (3) 40 Elective Mechanical Controls Mechanical Engineering Senior MEEN 442 (3) 40 Elective Computer Aided Engineering of Intelligent Systems Chemical Engineering Senior CHEN 464 (3) 40 Elective Process Control and Instrumentation Chemical Engineering Senior CHEN 451 (3) 40 Elective Polymer Engineering Electrical Engineering Senior ELEN 476 (3) 40 Elective Neural Networks and Implementation Electrical Engineering Senior ELEN 422 (3) 40 Elective Physical Implementation of Intelligent Systems New Engineering Minor in Intelligent Systems

  6. Activities using Smart Materials • ENGR 111/112 • Butterfly demonstration • ThermobileTM demonstration • Wire heat engine demonstration • Reconfigurable wing experiment • Underwater Propulsion Machine Project • Walking robot project (Stiquito) • ENGR 214 • Torque tube experiment • Piezoelectric beam demonstration

  7. Walking Robot Project • Project for students in an introductory engineering class (ENGR 111/112) • Robot specifications: • Must be actuated by SMAs • Goal is maximum distance in 3 minutes • Only contact can come from ground • Must be an autonomous system

  8. Multicultural Stiquito

  9. ENGR 111/112 integrated with AERO 401/402 • There are two primary objectives: • Let first year students gain practical experience working on the design and construction of an aerospace vehicle while working with upperclassmen. • Allow seniors to learn and develop important project management skills needed in the workplace today.

  10. ENGR 111/112 integrated with AERO 401/402 • Possible Projects for ENGR 111/112 students • Research Similar Aircraft • Helps to develop research skills in freshman • Allows seniors to effectively manage their time on important design issues • Internal Arrangement of Systems • Helps to develop spatial thinking in freshman • Allows seniors to focus on the actual system design • Landing Gear System • Allows freshman to use basic statics to determine landing gear requirements • Also allows freshman to develop an important mechanical system in the overall design • Study of New Technologies • Lets freshman learn the new and exciting technologies in engineering • The freshman research gives seniors a chance to gain important data and use towards the design of their aircraft.
