  1. Team 16 : Project MinotaurPresenter : John Hubberts Project OverviewHome security robot capable of monitoring the user’s home while they’re away. Can be manually controlled through a website or configured to patrol the house autonomously. Uses Kinect to capture video and identify intruders.

  2. Formal Definition of Criticality Levels • High Criticality • Failures that could result in physical danger for the user. • Acceptable mean failure rate: λ < 1e-9 • Moderate Criticality • Failures that could cause irreparable damage to the device, but wouldn’t pose danger to the user. • Acceptable mean failure rate: λ < 1e-7 • Low Criticality • Failures that could limit but not eliminate the device’s capabilities. • Acceptable mean failure rate: λ < 1e-6

  3. Highest Risk Components Microcontroller (PIC24FJ128GA) • High Complexity • Widely used • High Noise H-Bridge (L298P013TR) • Handles large currents • Potential for stalling if motors are stuck Switching Regulators (TPPS5450-Q1– 7.2V, LM25085 – 12.0V) • Have the ability to draw substantial amounts of current from the battery • (From our experience) heats up very rapidly
