Description

Technical Field

[0001] This utility model relates to the field of sweeping robot circuit technology, and in particular to a sweeping robot circuit system with stair cleaning function. Background Technology

[0002] Rapid technological advancements have spurred a new generation of intelligent products, exemplified by robotic vacuum cleaners. To date, numerous additional functions have been developed, such as wet mopping, automatic docking, UV disinfection, house mapping, and regular cleaning, in addition to standard features like collision avoidance and fall prevention. These characteristics enable robotic vacuum cleaners to perfectly clean single-story houses without human intervention. However, challenges arise when dealing with multi-story houses or houses with varying surface levels on a single floor. In such cases, robotic vacuum cleaners cannot operate effectively to thoroughly clean all surfaces. This would require the assistance of multiple robots or humans, which is neither cost-effective nor aligns with the primary purpose of home automation. Utility Model Content

[0013] Figure 2 This invention proposes a system path planning process for a sweeping robot circuit system with stair cleaning function. Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example

[0017] Please see Figure 1-2 This utility model provides a technical solution: a sweeping robot circuit system with stair cleaning function, including a microprocessor, as well as a collision sensor, a distance sensor, a fan, a motor drive module, a reduction motor, wheels and an encoder;

[0018] The output of the microprocessor is electrically connected to the input of the collision sensor, distance sensor, and fan. The motor drive module and geared motor are electrically connected to the microcontroller. The geared motor is connected to the wheel. The collision sensor is a micro switch. The distance sensor is model HY-SRE05. The fan is model BFB1012UH. The motor drive module is model L298N. The geared motor is model JGY370.

[0019] Operating principle: The system's actuators consist of six DC motors and a blower. Microswitches are used as anti-collision sensors to stop the robot's movement after it collides with an object. When the blower is running, it utilizes the vacuum generated on the blower's intake side to provide suction. This system is specifically designed for climbing obstacles, not for climbing obstacles. Climbing obstacles would require increasing the number of sensors.

[0020] This program is built on the Arduino IDE and uses the Arduino C++ programming language. It is broken down into subprocesses, one for each robot action, such as forward, backward, sideways, 90-degree clockwise rotation, and counter-clockwise rotation. These subprocesses are called when needed.

[0021] The main routine begins with a position initialization subprocess. The goal of this subprocess is to find the nearest corner of an open space region, assuming that the robot is randomly placed in an open space region at the start of the test.

[0022] Upon reaching the nearest corner, the robot will begin a round-robin area coverage process. The arena used in this study is an unobstructed arena surrounded by 30cm walls. By using path planning, the robot will cover 100% of the area, visiting each grid at least once.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
