1. Introduction
The UCTRONICS Smart Bluetooth Robot Car Kit is a flexible vehicular kit particularly
designed for education, competition and entertainment.
The kit has an intelligence built in so that it guides itself whenever an obstacle comes ahead
of it. An Arduino development is used to achieve the desired operation. With the help of a
small servo motor, it scans the area left and right in order to find the best way to turn. An
ultrasonic sensor unit is used to detect any obstacle ahead of it that sends a command to the
Arduino Board. Depending on the input signal received, the Arduino microcontroller
redirects the robot to move in an alternate direction by appropriately actuating the motors
interfaced to it through a motor driver IC.
When all the necessary components are getting together, a robot car comes up!
A robot is a machine that can perform some task automatically or with guidance. Robotics is
generally a combination of computational intelligence and physical machines (motors). Due
to their high level of performance and reliability, the robot gets the splendid popularity in
our daily life.
Come up; let’s go into a Robot World!

2. Parts Introduction
2.1 Uno R3 Board for Arduino
This is the new Uno R3 board for Arduino. In addition to all the features of the previous
board, the Uno now uses an ATmega 16U2 instead of the 8U2 found on the Uno (or the FTDI
found on previous generations). This allows for faster transfer rates and more memory. No
drivers needed for Linux or Mac (.inf file for Windows is needed and included in the Arduino
IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.
The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new
pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the
voltage provided from the board. The other is a not connected and is reserved for future
purposes. The Uno R3 works with all existing shields but can adapt to new shields which use
these additional pins.
Note: The Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some
computers. We have tested and confirmed that the R3 can be programmed in older versions
of the IDE. However, the first time using the R3 on a new computer, you will need to have
Arduino 1.0 installed on that machine. If you are interested in reading more about the
changes to the IDE, check out the official Arduino 1.0 Release notes!

2.2 HC-SR04 Ultrasonic Sensor Module with Bracket / Holder
The HC-SR04 ultrasonic sensor module for Arduino is used for obstacle detection. Ultrasonic
sensor transmits the ultrasonic waves from its sensor head and again receives the ultrasonic
waves reflected from an object.

2.2.1 Working Principle

www.uctronics.com
The ultrasonic sensor emits the short and high frequency signal. These propagate in the air
at the velocity of sound. If they hit any object, then they reflect back echo signal to the
sensor. The ultrasonic sensor consists of a multi vibrator, fixed to the base. The multi vibrator
is combination of a resonator and vibrator. The resonator delivers ultrasonic wave generated
by the vibration. The ultrasonic sensor actually consists of two parts; the emitter which
produces a 40 kHz sound wave and the detector detects 40 kHz sound wave and sends
electrical signal back to the microcontroller.
Ultrasonic working principle
The ultrasonic sensor enables the robot to virtually see and recognize object, avoid obstacles,
measure distance. The operating range of ultrasonic sensor is 2 cm to 450 cm.
