## Abstract

Embodiments of the present disclosure relate to a self-driving system having an RFID reader and a built-in printer. In one embodiment, a self-driving system includes a mobile base having one or more motorized wheels, the mobile base having a first end and a second end opposing the first end, a console coupled in an upright position to the first end of the mobile base, and a tag reader integrated with the console, the tag reader having a sensor surface facing upwardly.

## Claims

### Claim 1

A self-driving system, comprising:
a mobile base having a first end and a second end opposing the first end, the mobile base having one or more motorized wheels;
a console coupled to the first end of the mobile base, the console having a longitudinal direction that is perpendicular to traveling direction of the self-driving system;
a printer integrated with the console;
a display coupled to the console;
a first camera disposed at the display, the first camera facing the first end and being operable to identify an operator;
a second camera disposed at the console, the second camera facing the first end and being operable to detect a low-profile object, the second camera pointing to a direction that is at 30 degrees to 85 degrees with respect to the longitudinal direction of the console;
a third camera disposed at the console, the third camera facing the first end and being operable to detect an object so that a pre-determined distance is maintained between the self-driving system and the object; and
a fourth camera disposed at the mobile base, the fourth camera facing the first end and being operable to detect an obstacle, the fourth camera pointing to a direction that is at 60 degrees to 125 degrees with respect to the longitudinal direction of the console.

### Claim 2 (depends on 1)

The self-driving system of claim 1, further comprising:
a roll paper feeder disposed at the console; and
a paper discharge port operable to discharge a paper sheet from the roll paper feeder.

### Claim 3 (depends on 1)

The self-driving system of claim 1, further comprising:
an ultra-wideband (UWB) based device coupled to the console, the UWB based device being operable to determine position of the self-driving system.

### Claim 4 (depends on 1)

The self-driving system of claim 1, further comprising:
a basket disposed at a side of the console.

### Claim 5

A self-driving system, comprising:
a mobile base;
a console coupled to the mobile base, the console having a longitudinal direction that is perpendicular to traveling direction of the self-driving system;
a printer integrated with the console;
a roll paper feeder disposed at the console;
a paper discharge port disposed at the console;
a display coupled to the console;
a first camera disposed at the display, the first camera being operable to identify an operator;
a second camera disposed at the console, the second camera being operable to detect a low-profile object, the second camera pointing to a direction that is at 30 degrees to 85 degrees with respect to the longitudinal direction of the console;
a third camera disposed at the console, the third camera being operable to detect an object so that a pre-determined distance is maintained between the self-driving system and the object; and
a fourth camera disposed at the mobile base, the fourth camera being operable to detect an obstacle, the fourth camera pointing to a direction that is at 60 degrees to 125 degrees with respect to the longitudinal direction of the console.

### Claim 6 (depends on 5)

The self-driving system of claim 5, wherein the paper discharge port is disposed at a first side of the console and the roll paper feeder is disposed at a second side of the console opposite the first side.

### Claim 7 (depends on 6)

The self-driving system of claim 6, further comprising:
a positioning device coupled to the console.

### Claim 8 (depends on 7)

The self-driving system of claim 7, further comprising:
a basket disposed at a side of the console.
