Description:

     This project is a Bluetooth controlled robot. 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, stop move left, move right. These commands are sent from the Android mobile to the Bluetooth receiver. Android based robot has a Bluetooth receiver unit which receives the commands and give 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.

Description:

   An OBSTACLE AVOIDING ROBOT is one which can avoid an obstacle by using ultrasound sensor and navigate in its own path.

Applications:

• Obstacle avoiding robots can be used in almost all mobile robot navigation systems.
• They can be used for household work like automatic vacuum cleaning.
• They can also be used in dangerous environments, where human penetration could be fatal.
