1. TEAM 9 - MRAV Ethical & Environmental Considerations
April 13, 2011

3. Environmental Considerations
MANUFACTURE
All components except motors, frame and ESCs are RoHS compliant.
Use Lead free Solder
check coating on frame, motors. Check for cadmium, hexavalent chromium
NORMAL USE
Battery monitoring will give relevant information.
WIFI module, gryo, accelerometer, ultrasonics, magnetometer

4. Environmental Considerations
DISPOSAL/RECYCLING
Recyclable materials used such as frame for aluminum, metal casings for motors, carbon fibre propellers.
LiPo battery can be disposed with regular trash after performing steps.
LiPo battery: discharge and soak in salt water for a week

5. Ethical Considerations
SAFETY
Propellers spin extremely fast at about 7000 RPM. Build protective sheath such as Parrot Drone, balance propellers carefully, provide elaborate instruction guide, warning labels.
LiPo battery can catch fire due to crash, release harmful toxins. Find other battery solutions?
Control algorithm extremely complex; could potentially contain bugs. Rigorous testing required along with regular firmware update. User manual must also contain known bugs and effects.

6. Ethical Considerations
WEATHER CONDITIONS
Dangerous to fly in windy conditions. Test in various conditions and rate reliability.
LiPo battery can catch fire due to crash, release harmful toxins. Find other battery solutions?
LIFETIME OF PRODUCT
Decrease weight, reducing load on motors hence requiring lesser energy.
Use less ‘heavy duty’ motors requiring lesser current.
Ensure FAA compliance, limit flight altitude decreasing energy consumption.
Ours can supply 4500 mAh
