Design of Automatic Sweeping Robot
ABSTRACT
With the continuous progress and development of technology and society, the application of robots has expanded from industry to other fields. In particular, service robots have penetrated our lives, work and economic aspects, and have played a great role. The sweeper robot is the most close to the human robot, it can replace people to complete the cleaning of the family ground, most likely to enter thousands of families to become part of the family life. It involves mechanical, electronic and computer related knowledge. It integrates mobile robot technology and cleaning technology into one. The research and Realization of automatic sweeping robot technology is aimed at changing people's life through technology. It has become the most challenging research topic in the field of household appliances. This paper mainly introduces the mechanical structure design and control system design of the automatic sweeping robot. The whole shape uses round cake, the motion mechanism adopts three wheels, and the rear wheel of the front wheel is driven by two

motors respectively. The cleaning mechanism adopts the transmission scheme of the worm drive and the belt wheel, and the control part adopts the switch circuit. Starting brush motor, The drive motor is controlled by the L298 motor drive module. using infrared sensor and photoelectric sensor to transmit the signal to AT89C51 single chip microcomputer to complete the automatic obstacle avoidance and fall prevention function of the robot. It can effectively complete the cleaning work under the coordination of the related mechanical structure.
Key word: Sweeping robot, Intelligentization, Sensor, Singlechip, Dodge obstacles
