Team 8:Recon RobotSafety and Reliability Analysis AbhinavValluru (presenter) Vinitbhamburdekar Arjun Bajaj Aabhas Sharma
Key Concerns • Reliability: • Electronics for power supplies • Motor control • Microcontroller ,GPS and wireless transciever • Safety: • Batteries • Burns • Unexpected behavior
Part failure risk • Heat • TB6612FNG H bridge • D24V6ALV step-down voltage converter • Complexity • PIC 32MX360F512L microcontroller • RN-131 G wireless transceiver
FMECA Analysis: • Major injuries predicted • Most severe: burn injuries • Criticality Levels • Low: nuisance failure • Elevated: risk of additional part damage • High: definite part damage • “+I” Suffix: Chance of personal injury
Steps to improve reliability • Minimize design weight • Less current draw from motors, low power dissipation • Longer battery life • Over-designing of power supplies • Exceed expected power & peak current ratings (20% or higher) • Lowest available temperature coefficients(C/W)
