Embodiment Construction

[0038] Such as Figure 1 to Figure 2 Shown is a self-propelled device according to one embodiment of the invention. In this embodiment, the self-propelled device is a lawnmower 1 . The self-driving device can also be a vacuum cleaner or the like. The lawnmower 1 has a housing 2 for protecting the internal elements. Inside the housing 2 is a drive unit 3 . The drive unit 3 can drive the mower 1 forward or backward. The driving unit 3 includes a power motor 31 and a roller 32 . In this embodiment, there are two rollers 32 that help the mower 1 move on the ground and reduce friction, namely a first roller 321 and a second roller 322 . The first roller 321 and the second roller 322 are symmetrically located on both sides of the lawnmower 1 . There are also two power motors 31 , and each power motor 31 independently drives the rollers 32 and changes the rotation speed of the rollers 32 . When the speeds at which the two power motors 31 drive the rollers 32 to rotate are cons...

Abstract

The invention relates to a control method of a self-propelled device guidance system. When the self-propelled device enters a guidance operating mode, the self-propelled device searches for wire until a first sensing element and a second sensing element which are on the self-propelled device are located on both sides of the wire. The first sensing element and the second sensing element detect sensing signals transmitted from the wire respectively, and pass the sensing signals to a control unit. The control unit controls a drive unit and drives the self-propelled device to move along the wire, and the first sensing element and the second sensing element are kept to be symmetric with relation to the wire. The self-propelled device of the invention, guided by the wire, can quickly and accurately enter a docking station for charging.

Description

technical field [0001] The invention relates to a control method of a self-driving device guidance system. Background technique [0002] At present, with the accelerated pace of human life, automated home devices are becoming more and more popular around the world. Because it can work automatically and does not require human manipulation all the time, people can be freed from heavy family tasks and thus have more leisure time. Such automated home appliances include, for example, robotic vacuum cleaners mainly used for house cleaning, and robotic lawn mowers mainly used for gardening, and the like. [0003] Such automated home devices have some technical problems to be solved, including dividing the work area and making it work within the work area. A common idea is to place boundary annunciators on the boundaries of the work area. The boundary annunciator can send a signal to automatic equipment to prevent the equipment from exceeding the boundary when it is working. For...
