ABSTRACT:
A self-driven robotic cleaning apparatus and method thereof which can reduce the production cost and shorten the cleaning time and thereby increase a cleaning efficiency, comprising: an infrared heat detecting circuit which senses infrared heat emitted form a human body and pet animals to thereby output a signal sensed from the same to the microprocessor; a front/rear operation motor driving circuit for receiving a driving signal outputted from the microprocessor to thereby rotate driving wheels in either a front or rear direction, a steering motor driving circuit for receiving the driving signal generated from the microprocessor to rotate the wheels and thereafter to change the direction of the wheels; an ultrasonic wave transmitting circuit for receiving an ultrasonic wave transmitting signal from the microprocessor to thereafter transmit the ultrasonic waves; an ultrasonic wave receiving circuit for receiving the ultrasonic waves transmitted from the ultrasonic wave transmitting circuit after the waves are reflected from an obstacle and thereafter for inputting a signal to the microprocessor indicating receipt of the ultrasonic waves by the ultrasonic wave receiving circuit; and a cleaning motor driving circuit for receiving the driving signal from the microprocessor to drive a cleaning motor and thereafter to perform a cleaning job.
