  2. Problem Statement MARV2 is in an empty room. When MARV2 senses its battery is low, it needs to autonomously locate the charging station and dock with it.

  3. Background Information • Irobot produces an autonomous vacuuming robot called Roomba to perform household cleaning. • When the robot’s battery voltage is low, it uses infrared sensors to find its recharging station.

  4. Solution Statement Using a mechanical switch to simulate a battery low condition, our software sends MARV2 into a search routine where it aims to detect an infrared emitter. The direction of both motors will be determined by the output voltage of two infrared sensors mounted on one side of the unit.
