- the position regulation part 204 connects the first support part 202 and the second support part 203 in the vertical direction, which not only makes it easy to reconnect when replacing the sensor part 201 and the second fixing part, but also provides initial position information. This is because it may not be difficult to obtain.
- the fixing force can be increased when connecting the first support part 202 and the second support part 203.
- Figure 8 is a flowchart showing an example of a method for assembling a smart logistics vehicle according to an embodiment of the present invention.
- the second support part 203 required for replacement in case of failure of the sensor part 201 can be obtained and stored (S801). Afterwards, a failure of the sensor unit 201 may be determined (S802). If the sensor unit 201 is broken (YES in S802), the second support unit 203 is also replaced along with the sensor unit 201 while the second support unit 203 is fixed to the sensor unit 201 ( S803). Ultimately, by replacing the sensor unit 201 and the second support unit 203, the AMR can be restarted immediately by quickly aligning the initial position of the replaced sensor unit 201 through the position regulating unit 204 (S804).
- the time required to initialize the replaced sensor unit based on initial location information can be shortened.
- smart logistics vehicles can be started immediately, improving the operation rate.
- Computer-readable media includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is. Accordingly, the above detailed description should not be construed as restrictive in all respects and should be considered illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
