Android mobile Bluetooth operated robot
Android
mobile Bluetooth operated robot
Abstract:
Many
of the wireless-controlled robots use RF modules. But this project makes use of
Android mobile phone for robotic control. The control commands available are
more than RF modules. For this the android mobile user has to install an
application on her/his mobile. Then user needs to turn on the Bluetooth in the
mobile. The wireless communication techniques used to control the robot is
Bluetooth technology. User can use various commands like move forward, reverse,
move left, move right using these commands which are sent from the Android
mobile. Robot has a Bluetooth receiver unit which receives the commands and
gives it to the microcontroller circuit to control the motors. The
microcontroller then transmits the signal to the motor driver IC’s to operate
the motors.
The power supply consists of a step down transformer
230/12V, which steps down the voltage to 12V AC. This is converted to DC using
a Bridge rectifier and it is then regulated to +5V using a voltage regulator
7805 which is required for the operation of the microcontroller and other
components
