Embodiment Construction

[0040] refer to figure 1 , shows an embodiment of a navigation system 100 comprising: a plurality of signal sources 102 deployed in a predetermined area; and a processor arranged to process the electromagnetic signal to identify the location of the signal source 102 so as to determine the current position of the guide machine 104 with reference to the location of the signal source 102; and the processor is also arranged to In order to determine the route of the guide machine 104 traveling from the current position to the destination location in the predetermined area.

[0041] In this embodiment, the guide 104 has four wheels 106 for driving the guide 104 along a surface (eg, the ground). The guide machine 104 also includes a handle 108 that can be grasped by a user so that the guide machine 104 can navigate and actively guide the user to move from one location to another. In one example, the guide machine 104 may be used as a robotic guided vehicle or a robotic guide dog fo...

Abstract

The invention discloses a guide machine and a control method of a navigation system. The navigation system includes: a plurality of signal sources deployed in a predetermined area; and a guide machine comprising a signal receiver arranged to receive electromagnetic signals emitted from one or more of the plurality of signal sources; and a processor arranged to process the electromagnetic signal to identify a location of the signal source and thereby to determine a current position of the guide machine with reference to the location of the signal source; wherein the processor is further arranged to determine a path for the steering machine to travel from the current location to the destination location in the predetermined area.

Description

technical field [0001] The present invention relates to a guidance machine and a control method of a navigation system, in particular, though not exclusively, to a robotic guide dog based on RFID technology. Background technique [0002] A common tool for presenting directional or orientation information to users or customers is the use of visual markers or reference points in order to communicate orientation and orientation to the user. However, for the visually impaired, visual markers may not be useful, or provide any significant assistance, and therefore, an alternative form of navigation aid is needed. [0003] Tactile markers (e.g., tactile tiles laid on floor surfaces) could be a possible solution for aiding navigation for the visually impaired. These tactile markers may have a predetermined shape and layout that provides a tactile sensation to the user when the user steps on or touches the tile. These tactile signs, while helpful for providing reference information...
