RequirementsThe main requirement of the project is to design a remotely operated toy car.The design should be economical and marketable.The car should be operated from a distance place by a computer viewing the road from a wireless camera.The car should be worked on with the given RF modules T5-434 and R5-434.The heart 0f the car should be a Microcontroller IC PIC 16F877A.
FUNCTIONALITYOverall FunctionalityThe operational input is fed from the keyboard of the computer.The Visual Basic program in the computer outputs the ASCII value of the input from the Serial Port.MAX232 IC circuit converts the logical voltage levels of the serial port into 5V and 0V voltage logical levels which are the inputs of the transmitter circuit.
FUNCTIONALITYT5-434 IC transmits ASCII values of each keystroke.R5-434 receiver IC in the vehicle receives radio signals from the T5-434.Receiver IC outputs an electrical signal of the ASCII code to the PIC circuit.PIC16F877A recognizes the ASCII code and send direction controlling signals and speed controlling signals(PWM) to motors via a H-bridge. (Half of a L298 IC)L298 circuit supply power to motors according to inputs.

IMPLEMENTATION CHALLENGES• What is this?????• How can we do this???
IMPLEMENTATION CHALLENGESFaults of the electronic componentsDifficulties faced in identifying faultsMinimizing the area occupied by circuitsFinding a suitable body for the chassisMounting all the circuits and the battery inside the bodyMaking the car as attractive as possible
Production ProcessA lot of new things. So it’s the time for team work.Every team member specialized in different areas. A deadline was also given to make the process more efficient. After about a week we met our mentor for further clarificationsThen the real production started…….
COSTINGFor the electronic components :- Rs.700.00For the body:- Rs 125.00Packaging material and stationary:- Rs 100.00
MARKETING PLANOur main target in marketing this product is……. children.• Not only as a toy. But for other purposes too….. Why should someone buy this product? Price is affordable Attractive appearance
