RETRACTED: A Smart Device for a Preliminary Dental Examination Based on the Internet of Things

Device components.

NO.	Name of component	The task of the components in the device
1	Arduino UNO board, Figure 4 [22]	This piece is considered to be the basis of the project, and it is this on which any electrical project that comes to the human mind is built.
2	Breadboard, Figure 5 [22]	A breadboard is a solderless tool used to test circuit layouts and model-wide equipment. Most electronic sections in electronic circuits can be coupled by inserting their leads or terminals into the apertures and then forming connections with wires where appropriate.
3	Joystick, Figure 6 [23]	This joystick is a component that communicates directly with the user by issuing commands to move the robotic arm right, left, backward and forward. Each analog channel (axis) can have values ranging from 0 to 1023. The value of analog is roughly 512 when the joystick is in the center position. It is used to control the movement of the arm in all directions.
4	Robotic arm, Figure 7 [24]	The robotic arm consists of two servo motors. The robotic arm can be moved along the X and Y axis in both negative and positive (2-D) using a joystick.
5	Male-female jumper wires, Figure 8 [9]	Male-female jumper wires are used to connect all components with UNO.
6	Cable, Figure 9 [9]	This cable is used to link a computer with UNO.
7	Servo motor, Figure 10 [25]	This piece is the basis of the movement of the arm in all directions.
8	Camera, Figure 11 [8]	A 5-meter wired camera is installed on the head of the robotic arm and is connected to the dentist’s phone or laptop.
