1. Ethical & Environmental Impact Analysis

2. Environmental Impact  Manufacturing: Hazardous Chemicals used in the manufacturing of the PCB, Li+ Battery, ICs  Normal Use: Power consumption Small coal usage for power to recharge battery  Disposal: Non-biodegradable Ics, PCB Hazardous Chemicals to dispose of Li+ Battery

3. Addressing Environmental Impact  Manufacturing: Area of PCB is small to begin with. Keep chassis simple.  Normal Use: 7.4 V drawing ~0.21 A = 1.55 W – Not an issue Battery is not powering components while off  Disposal: Instruct on proper disposal of Li+ Battery Proper disposal/recycling of PCB Possibly Recycle motors & Sensors

4. Ethical Challenges  Safety: Shock/Burn user Battery explosion Fire  Misuse: Overcharging battery Reprogrammed for Kamikaze missions

5. Addressing Ethical Challenges  Safety: Enclose PCB and cables for manufacturing Warning label on parts that may get hot Warning label on battery and enclosure Incorporate a fuse in case of a short  Misuse: Explain in User Manual the importance of not overcharging & warn about consequences Disconnect programming header
