“GSM (SMS) Controlled Wireless Car” is automatic robotic car which capable of receiving a set of command instructions in the form of Short message service and performs the necessary actions. We will be using a dedicated modem/mobile at the receiver module i.e. with the robot it self and send the commands using SMS service as per the required actions.
The mobile unit which is dedicated at the robot is interfaced with an intellectual device called Micro controller so that it takes the responsibility of reading the received commands in the form of SMS from the mobile unit and perform the corresponding predefined tasks such as move front or back, left or right etc. The micro controller is also interfaced with few DC motors in order to move the robot in different directions. The ON and OFF of the DC motors depends on the direction it has to move which is the complete responsibility of the controller to take those intelligent decisions.
