Problems solved by technology

However, when the illumination brightness of the area is changed or an object with a shape similar to a reflector is recognized, it is also possible to accumulate distance errors due to misjudgment; in addition, when the illumination brightness of the area is too high or too low, the CCD camera will not be able to identify The reflector makes the mobile robot unable to do position detection; moreover, because the mobile robot must be equipped with a CCD camera, it increases the manufacturing cost of the mobile robot

Embodiment Construction

[0065] Please refer to FIG. 2 , which is a circuit block diagram of the self-propelled device and the calling device of the present invention. The self-propelled device 2 includes a power detection unit 21, a power supply unit 22, a first control unit 23, a first radio wave transmitting unit 24, a first radio wave receiving unit 25, a driving unit 26 and a first The charging interface 27 ; the calling device 3 includes a second control unit 31 , a second radio wave transmitting unit 32 , a second radio wave receiving unit 33 and a second charging interface 34 . Among them, the power detection unit 21 can detect the power of the power supply unit 22, and transmit the detection result to the first control unit 23. When the power is too low, the first control unit 23 will send a first radio through the first wireless transmission unit 24. wave signal (S1), when the second radio wave receiving unit 33 receives the first radio wave signal (S1), it will send the signal back to the s...

Abstract

The invention relates to a route leading method of self propelled device, which leads the self propelled device to a position which is fixed by a calling device to implement the relating work, the self propelled device is provided with a wireless electric wave receiving unit with pointing function, the calling device is provided with a wireless electric wave launching element, the route lead method of the self propelled device comprises the following procedure; a. the wireless electric wave lauching element sends out wireless electric wave route leading signal; b. the wireless electric wave receiving unit receives the wireless electric wave route leading signal; c. according the intensity of the wireless electric wave route leading signal, and makes the self propelled device decide the advancing direction and goes forward to the direction. With according to the strong and weak and direction of the wireless electric wave route leading signal, the invention decides the direction of the calling device, and moves forward along the direction, decide the distance between the calling device according the strong and weak of the received wireless electric wave route leading signal and decides the distance from the calling device.

Description

technical field [0001] The invention relates to a path guiding method for a self-propelled device, in particular to a self-propelled device that guides the self-propelled device to the calling device by receiving a radio wave path guiding signal sent by the calling device. The path guidance method of the device. Background technique [0002] With the advancement and development of science and technology, there are various types of modern robots and their functions are becoming more and more powerful. Among them, mobile robots play a very important role in cleaning the home environment, handling heavy objects in factories and even exploring outer space. [0003] Take a mobile robot and its corresponding charging station as an example. In order to continue to work, the mobile machine must return to the charging station for charging before the power is exhausted. Please refer to FIG. 1 , which is a circuit block diagram of the first existing robot charging system. The existin...
