You will need an Arduino Uno board for interfacing microcontroller with Bluetooth module and Servo Motors. You need to download the Android app ArduinoBluetooth which is available in Play Store. Now connect the Bluetooth device to the smart phone in which you had installed the app. You will program the microcontroller in such a way that say whenever you press forward direction key in the ArduinoBluetooth app, the microcontroller will make your robot to walk in forward direction. Similarly we will program the microcontroller for the commands backward, left and right. Based on the direction Key you press, your microcontroller will make your robot to walk into that particular direction.

Project Description:

1. Arduino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. Servo Motors: A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position
3. Motor Driver: Generally the Arduino board is not capable of providing required amount of current for running the motors. So we use a device called Motor Driver which will provide sufficient current for driving the motors.
4. Bluetooth: HC-05 Bluetooth module is a generally used to provide a common platform for connecting Smart Phone with Microcontroller. Communication between Smart phone and Bluetooth will be Serial.

Project Implementation:

1. Interface the Bluetooth module and Servo Motors with the Arduino board
2. Power your robot and upload the code
3. Install ArduinoBluetooth app from Playstore
4. Connect your Mobile to the Bluetooth module
5. Once your mobile and Bluetooth are connected, test your Walking Robot by pressing direction keys in the ArduinoBluetooth app.

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
