Project Description
Key Objectives Debug I2C communication interface Design & integrate sensor circuitry Design & Implement redundant safety features Design simple transport mode Incorporate ride vibration mitigation Fabricate and assemble prototype Modify electronics to address known issues
Mission Integrate existing hardware with newly designed
subsystems to deliver functional prototype ready for software development
Design Concept
Safety• Chain guards• Emergency stop
buttons• Bumper System
Enclosure• Transparent &
water resistant electronics box
Transport• Collapsible handle• Drivetrain disengagement
Modularity• Fully modular bolted connection
architecture
Sensor Suite• Sonar• Infrared• Bump• Photodiode• GPS• Accelerometer• Moisture sensor• Temperature• Motor Encoders

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
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
