Doodle Drive Presenter: Alex Curtis Team 6 Environmental Impact TCSP
Project Overview • Android application as controller • Robot vehicle with microcontroller • Path will be drawn in Android application and the vehicle will follow that path • Outdoor mode with GPS, Google Maps, Compass • Indoor mode with tilt control
Environmental Lifecycle Impact Analysis • MANUFACTURE • Printed Circuit Board • Components • Batteries • NORMAL USE • Maximize lifetime • Energy consumption • DISPOSAL/RECYCLING • Recycling of possible components (batteries, robot, electronics) • Proper disposal if recycling not possible
MANUFACTURE • Printed Circuit Board • Choose manufacturer and specifications correctly • RoHS (restriction of hazardous substances) compliant solder finish • Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominateddiphenylether • Advanced Circuits uses tin copper alloy as solder finish, another common example is Electroless Nickel/Immersion Gold (ENIG) • Minimize area of PCB • Components • RoHScompliant • Batteries • Device only compliant with Nickel Metal Hydride • Environmentally friendly, don’t use toxic chemicals of alternatives (e.g. Cadmium)
NORMAL USE • Maximize product lifetime – user awareness • Batteries • Store in cool, dry, place • If not used for months at a time, recharge periodically • Charge cycles variable, 400-1000 times, depends on use (don’t overcharge) • Energy Consumption • NiMH high self discharge rate (1-4% daily) • ~500mA at 5V, ~100mA at 3.3V, ~1500mA at 7V (P = 2.5+0.33+10.5= 13.33W) • Battery pack 2800mAh capacity • Under ideal conditions can run for 1.75hr
DISPOSAL & RECYCLING • Batteries • Nickel Metal-Hydride (NiMH) • Should be recycled in proper repository • If recycling unavailable, don’t dispose of 10+ at once (Buchmann) • Physical Robot • Recycle plastic chassis • Rubber wheels (if possible) • Electronic Components • Electronic recycling center
