2 Statement of purpose Robot Vacuum (RVC) - An RVC automatically cleans and mops household surface. - It goes straight forward while cleaning. - If its sensors found an obstacle, it stops cleaning, turns aside, and goes forward with cleaning. - If it detects dust, power up the cleaning for a while - We do not consider the detail design and implementation on HW controls. - We only focus on the automatic cleaning function.
