Self Sustaining Solar Power Robot Final Presentation Mason Drew Mark Nolan Wesley Varghese Problem Objective • Light-Seeking – be able to locate the strongest light source in the area and navigate toward it. • Mobile – be able to navigate on a flat surface without obstacles. • Monitor Energy – monitor the battery’s energy level at all times. It should know when it needs to seek more energy and it should also know when the battery is done charging. • Solar-Rechargeable – once in a strong light source, the robot should enter a charging mode where it consumes very little power and stores the energy into rechargeable batteries. • Self-sustaining – operate without any assistance from the outside world. Light-Seeking • Light Measurement Circuit – multiple sensitivity circuits • Algorithm – dynamic dead band Mobile Sonar (object avoidance) Monitor Energy • Voltage Measurement Circuit • LED Solar-Rechargeable • Solar Array • Charge Circuitry I/O Pin BOE-bot Solar Array Solar Array 5V regulated Sense Battery Monitor IC Ni-MH I/O Pin Self-Sustaining Conclusion • Successes • Failures • Lessons Learned
