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.
