  2. Project Summary • Small autonomous robots • Solar powered • Interact with the environment • Operate in sunlight and low light conditions • Several operational modes • IR communication

  3. Overall Block Diagram

  4. Proposed Hardware Flow Chart

  5. Software Flow

  6. Contact Operation

  7. Completed Tasks • Solar Panel Testing • Power Regulation • Microcontroller Setup • A/D Interfacing • Motor Circuitry & Interfacing • Light Sensor • Chassis Fabrication

  8. How It’s Connected

  9. Up Close

  10. Bug In Motion

  11. Power Values • Low Battery = 5.8 Volts • Out of Regulation = 5.2 Volts • Motor Controls/Sensors • 36 mA while active • 220 mA with both motors • less than 1 mA while disabled • Microcontroller • 30 mA while active • Less than 1 mA on low power

  12. Solar Array • Maximum Output Voltage = 8 Volts • Maximum Output Current = 1.5 Amps • Maximum Power Output = 12 Watts • Estimated Needed Power = 1.5 Watts • 6[V]*.25[A] = 1.5[W] • Actual Needed Power =1.74[W] • Ptotal=5[V]x294[mA]+3.3[V]*82m=1.74[W]
