Problems solved by technology

But the problem encountered in this obstacle avoidance method is: in order to determine the scope of the working area, it is necessary to drive along the outline of the working area without actually performing cleaning work, so the actual effective operating time of the robot vacuum cleaner body is reduced.
In addition, the use of infrared ranging sensors is also a relatively common obstacle avoidance method, but cleaning robots using infrared ranging sensors are susceptible to environmental influences in addition to the aforementioned problems.
At the same time, it needs to be controlled by adding a photoelectric code disc or a remote control. The price of its components is high, and the algorithm program is complicated, which increases the complexity of the robot vacuum cleaner system, and its reliability will be affected.

Abstract

The invention relates to an automatic obstacle-avoiding method of a robot cleaner and a control method thereof. The robot cleaner comprises a dust collecting body, a base station and a control circuit. The dust collecting body is provided with a left wheel and a right wheel. The top of the base station is provided with an infrared emitter. The upper part of the dust collecting body is provided with an infrared receiver which receives an infrared communication signal emitted from the base station. The control circuit comprises a singlechip, a drive circuit, a current feedback circuit, an anti-dropping circuit, an infrared receiving circuit and a voltage monitoring circuit. The singlechip controls the operation of the robot cleaner according to the relative positions of the dust collecting body and the base station. When meeting obstacle, the singlechip judges and controls the dust collecting body to avoid the obstacle and next moving direction. After collecting dust for a period of time, the dust collecting body returns to the base station for pumping the dust and charging automatically. The robot cleaner manufactured by the invention has simple structure, reliable control and stable performance and can fulfill unattended intelligentized cleaning.

Description

technical field [0001] The invention relates to a control method for automatic obstacle avoidance of a robot vacuum cleaner. Background technique [0002] Commonly used robot vacuum cleaners often use ultrasonic sensors to avoid obstacles when encountering obstacles such as furniture or walls. However, the problem encountered in this obstacle avoidance method is that in order to determine the scope of the working area, it is necessary to drive along the contour of the working area without actually performing cleaning work, so the actual effective operating time of the robot vacuum cleaner body is reduced. In addition, using an infrared ranging sensor is also a relatively common obstacle avoidance method, but a cleaning robot using an infrared ranging sensor is easily affected by the environment in addition to the aforementioned problems. At the same time, it needs to be controlled by adding a photoelectric code disk or a remote control. The price of its components is high,...
