Critical Risk Assessment Risk: Difficulty producing I2C functionality

Hardware and software incompatibilities and flaws produced multiple roadblocks

Roadblocks pushed back electrical & test schedules Learning curve for electronics system very steep Mitigation: Investigated alternate beagleboard OS Mitigation: Replaced I2C hardware to ensure proper

configuration Mitigations were unsuccessful for an extended

period – required revising of project goals

Page 6: Wandering Ambassador

State of Project Design meets all customer needs Mechanical systems complete on schedule

Motors and water pump function as designed Electronics 2-3 weeks behind schedule

Multiple issues encountered○ Hardware issues○ Software incompatibility

Cost: $500 under budget

Future Direction P11216 team has received customer and P11215

input on feature addition and optimization Water based vandal deterrent system Optimization of sonar placement and actuation Design and implementation of personality software Plant expansion system LCD placement & function plan
