Design a Compact Robotic Car Based on Microcontroller

The proposed product aims to design a compact robotic car which can be remotely controlled by a keyboard. The detailed information on the research, design and construction of a real-time remote control robotic car. The command to the robotic car will be given remotely through a keyboard. A comparative study has been implemented on the major components to be used in this project. They include microcontrollers, propulsion, sensors, power supplies, etc. The basic prototype which can be remotely controlled to move forward, reverse and change direction. The prototype consists of Atmel microcontroller, AT89C2051, based transmitter and receiver. The transmitter acts as a remote control which sends command to the receiver. The receiver is mounted on a chassis with motors and wheels attached. Received signals are decoded to control the movements of the motors. C / C++ programming language are used to create the interface within the receiver and transmitter. The prototype is compact, portable and operates like a normal car. It will be able to turn left, turn right, forward and reverse. All movements of the prototype are remotely controlled via the transmitter. Traction or speed control is achieved through generation of Pulse Width Modulation (PWM) codes. The PWM codes will vary the rotational speed of the motor.
