Embodiment Construction

[0018] The present invention is described in detail below in conjunction with specific embodiment:

[0019] Such as Figure 4 As shown, when the cleaning robot is placed in the room and started to work, it first performs an equidistant helical motion, and its pitch is equal to the effective cleaning width of the machine itself. The isometric helix pattern runs until it hits an obstacle. The obstacles mentioned here include general obstacles and cliff obstacles. When an obstacle is encountered, the machine exits the equidistant helix mode and enters the wall mode at the same time. When the machine encounters an obstacle, it begins to rely on its own wall sensor to find the wall and run along the wall, that is, the machine automatically adjusts its direction to maintain the continuous signal from the wall sensor, such as image 3 Shown: Walk forward when the sensor along the wall receives the wall signal. If the signal is lost, immediately adjust the speed of the driving whee...

Abstract

The invention relates to a path scheme for robots used for cleaning purposes, characterized in that it contains any kind of combinations of the isometric helix mode, the along-wall mode and the random modes. The robot uses combinations of these three modes while it working. The isometric helix mode is an isometric helix, involute or similar inward or outward helix motions. In the along-wall mode, motions along a wall or the surface of an object, which possesses the characteristics of a wall, are performed. In the along-wall mode, the judgment of a wall is realized through the sensors, which can be infrared photoelectrical sensor, ultrasonic sensor, photoelectrical screen or other sensors that can identify object surfaces. These combinations of the above three modes are cycled during the process of the robot's operation.

Description

Technical field [0001] The invention relates to a path planning for a robot, in particular to a path planning suitable for a cleaning robot. Background technique [0002] With the development of science and technology, home appliances have gradually moved towards the era of intelligence. In particular, some robots with certain functions have also moved towards the family. Such as: robot vacuum cleaner, etc. However, the operation planning (path planning) of the self-propelled robot vacuum cleaner has always been a technical difficulty in this project. It directly affects the working efficiency of the robot. Most current products of this type use a very inefficient random model. Robots take a lot of time and consume a lot of energy to do their jobs. However, the method of gyroscope positioning or electronic map positioning greatly increases the cost, and the price of the product is difficult to be accepted by ordinary families. Contents of the invention [0003] Regar...
