Learning Goals

Apply principles of reliability and probability theory to analyze the reliability of a real-time system (1)

Analyse a complex real-time system to determine if it can meet time and resources constraints (1)

Design a real-time system subject to multiple safety-critical, mission-criticial, and optimization requirements (2)

Evaluate multiple design alternatives and select the best real-time system design that meets the requirements (2)

Implement, as a team assignment, a robot guidance system (on real robot hardware) that adheres to learned best design principles (2), (5), (6)

Articulate to classmates the advantages of one's design, argue for the specific design decisions made, and explain empirically observed robot performance (3)

Argue for the best prioritization of conflicting design requirements in a real-time system (especially an autonomous, intelligent one) in a manner that best addresses safety, mission, and ethical concerns (4) (3)
