The document outlines the creation of a land robot controlled via Bluetooth using an Arduino microcontroller, which can be maneuvered through touch buttons or by tilting an Android phone. It details the components used, including DC motors, an RFID reader for station detection, and the assembly process of the robot's structure from corrugated plastic. The document also highlights the technical specifications of the Arduino board and motor driver used in the project.

2. OBJECTIVE
A land robot using an Arduino Micro Board was
made. The robot could be controlled using any
Android Phone via Bluetooth.
The controls could be sent to the robot by either
pressing buttons on the touch screen of the phone
or by tilting the phone in various directions which
changes the accelerometer values that correspond
to specific control commands.
The robot could also carry out station detection by
using the method of Radio Frequency Identification.

4. RFID (radio-frequency identification) is the
wireless non-contact use of radio-frequency
electromagnetic fields, for the purposes of
identifying and tracking tags attached to objects.
The Micro is a microcontroller board based on the
ATmega32U4, developed in conjunction
with Adafruit. It has 20 digital input/output pins
(of which 7 can be used as PWM outputs and 12 as
analog inputs), a 16 MHz crystal oscillator, a micro
USB connection, an ICSP header, and a reset
button. It contains everything needed to support
the microcontroller; simply connect it to a
computer with a micro USB cable to get started. It
has a form factor that enables it to be easily
placed on a breadboard.
The TB6612FNG motor driver can control up to two
DC motors at a constant current of 1.2A (3.2A
peak). Two input signals (IN1 and IN2) can be
used to control the motor in one of four function
modes - CW, CCW, short-brake, and stop. The two
motor outputs (A and B) can be separately
controlled, the speed of each motor is controlled
via a PWM input signal with a frequency up to

5. CHASSIS
The shape of the bot was cut from the large piece
of corrugated plastic board.
From the same corrugated plastic board, the shape
of the bot was cut out again, but with different
alignment of stripes.
Ample amount of superglue between the layers was
applied to permanently combine them.
The Castor Ball that was prepared earlier was
positioned at the middle of the top and secured
using superglue and screws.
Motor mounts to secure the motors on each side
were attached to the base using a mixture of
