Robot with Radio Frequency

This document presents a robot that uses RF technology to operate wirelessly. It consists of a transmitter section with a microcontroller, encoder, and RF transmitter. The receiver section has a battery, motor driver, microcontroller, RF receiver, and decoder. The microcontroller uses four ports, an oscillator, reset pin, and power pins to control a stepper motor via an H-bridge circuit. The robot can be operated remotely by sending command signals from the transmitter that are received and decoded to move the motors forward, backward, left, right. Potential applications include industrial, military, medical, and entertainment uses. Future improvements could include adding wireless GSM and motion detection capabilities.
