OCR 09WP 01/09/2568 1. The robot for guiding patients in positioning for X-ray imaging consists of a robot base (1) to support the battery (2) and a microcontroller board (3) to control the robot's operation. The drive system consists of four Mecanum wheels (4) connected to electric motors and gear sets (5). There is a four-sided aluminum frame (10) mounted on a plastic base (11) that is square in shape, with a space in the center of the plastic base (11) for installing internal components. There is an outer frame (12) and a square plastic plate (14) that serves as the top cover of the robot, with a slot for supporting the imaging device (18). On the front of the robot frame, there is a support structure (16) attached to support the display screen (17). Its unique feature is the drive system using Mecanum wheels (4), where the roller wheels are angled at 45 degrees to allow movement in all directions without changing the direction of the robot. The wheels are connected to electric motors and gear sets (5) to control both wheels, and a microcontroller board (3) sends movement control commands to all four motors. The robot can display instructions for patients on how to prepare for X-ray imaging. Patient positioning instructions for X-ray imaging are provided by the operator, who sends signals to control the image display system on the display screen (17) to display the image and instructions on the screen. The operator then sends signals to control the projection device (18), which projects the X-ray positioning image onto the target surface, namely the standing X-ray column inside the X-ray room, with the display controlled via a wireless control device. 2. A robot for guiding patients to position for X-ray imaging, according to claim 1, whereby the propulsion system comprises an additional wireless motion system using a wireless control button (13) that transmits signals to a receiver (6) attached to the robot to control the direction of movement of the robot, and an automatic line-following system using an infrared sensor module and decoder (7) to detect a guide line which is a black line on a white background as specified. 3. A robot for guiding patients to position for X-ray imaging, in accordance with claim 1 or 2, which is further equipped with an ultrasonic sensor (8) mounted on the robot base (1) which detects objects in the robot's path of movement and, when an object is detected at a specified distance, sends a signal to the microcontroller board (3) to stop the motor and emit an alert sound through the buzzer module (9). 4. A robot for guiding patients to position for X-ray imaging under one of the claims from Sections 1 - 3, in which the top plastic plate (14) has a handle (15) for moving the robot by hand.
