The smartphone controlled bot is operated via the bluetooth of your phone as the name suggests. The bot is controlled by a micro controller known as Arduino which is used by students and hobbyists all around the world for creating new stuff daily. It is driven by the motor driver L293D and powered by an 8 V battery. The basic structure rests on the chassis and is supported by a chaster wheel at the front. The arrow keys on the application instruct the bot to proceed in a specific direction. Voice commands received via the android application can also be used to control the vehicle. The device works on instruction provided through the smartphone in terms of 1, 2, 3, 4 and the numbers 1, 2, 3, 4 represents a direction the bot should take. The number is transferred from the smartphone to the bluetooth module of the bot. The data then is analysed by the micro controller and the motor drivers are driven accordingly.
