1 - Arduino Uno = The Arduino Uno is a microcontroller board
based on the ATmega328. It has 14 digital input/output pins (of which 6 can be
used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB
connection, a power jack, an ICSP header, and a reset button. It contains
everything needed to support the microcontroller and contains all the functions
and the systems to control our robot
2 - LCD monitor = It was used as a feed-back, describing
every function that the robot is doing.
3 - Ultrasonic sensor = It was used to avoid obstacles.
4- Line following sensor = We used two line following
sensors, one on each side of the robot, to make it follow the black line on the
floor.
5- Momentary Push-button Switch = We used four Momentary
Push-button Switches to allow the operator to choose different pieces in
different places.
6- RFID reader = Radio-frequency identification (RFID) is
the wireless non-contact use of radio-frequency electromagnetic fields to
transfer data, for the purposes of automatically identifying and tracking tags
attached to objects. We used to read specific points during the track, avoiding
any kind of mechanical contact.
RFID
tag = The tags contain electronically stored information. They act as a passive
transponder to emit microwaves or UHF radio waves. We used seven different tags
to point the specific places where the robot must take different actions.
An RFID reader transmits an encoded radio signal to
interrogate the tag. The RFID tag receives the message and then responds with
its identification and other information. This may be only a unique tag serial
number, or may be product-related information such as a stock number, lot or
batch number, production date, or other specific information.
* Resistors = We used four resistors of 330 ohms to drain the
power to the ground, avoiding the high signal to arduino.
7- Servo motor = This device is used to act as a hoist to
toll the car containing the selected pieces.
8- H-brigde = we used two different H-bridge to control four
wheels.
9- Battery(5V, 2.1 mAh) = We used a battery with 5V power on
the arduino, LCD screen, the servo, as well all the sensors.
* Battery (9V )= We used the battery with 9V to power on the
H-brigde with de DC motors.
* DC motor = We used four DC motor to spin the wheels, giving
movement to the robot.
* 4 wheels chassis = We used the four wheels chassis to
support all the devices used in the robot.
