Abstract
An automatic working machine which moves forward and turns back with a pre-determined shifted displacement to perform a task in a back and forth manner. The machine comprises sensors for detecting the boundaries of a defined area. The machine moves forward until the sensors detect a boundary or until a specific distance has been traveled, then the machine turns and proceeds forward in the opposite direction. The machine continues to perform in the specific back and forth motion until the task is completed.
