Then, after using the application we can send orders to the robot. Robot can receive this Bluetooth command using a Bluetooth decoder. The received signal is processed by the microcontroller with the aid of the decoder circuit. The microcontroller then sends commands to the motor driver IC to power the motors. To design our project we use the BLUETOOTH decoder to solve problems with RF-ID. Generally RF-ID has very limited controls. But the Android mobile phone with BLUETOOTH has more commands so we can easily operate it.
This is controlled by a mobile or mobile phone. In this project, the robot is controlled by a mobile phone that makes a call to the mobile phone connected to the robot. In the course of a call, if any button is pressed, a tone corresponding to the button pressed will be heard at the other end of the call. This tone is called a "dual tone multifrequency" (DTMF) tone. The robot perceives this DTMF tone with the help of the phone stacked in the robot.
The received tone is processed by the microcontroller with the help of the DTMF decoder. The microcontroller then transmits the signal to the motor IC to operate the motors. The camera mounted on the robot will give you detailed information of where the robot is and who is around. The signal is then transmitted to the observer via an audio / video transceiver.
