1) perf board (dummy pcb)
2) wires

3) encoder ht12e and decoder ht12d ic's, and l293d motor driver or you can use L298N if you are using a lipo or any other high current batteries.

4) rf modules

5) resistances 1M and 51K

6) led's

7) ic7805 voltage regulator

8) 2 dpdt switches

9) 4dc gear motors

10) any thing to mount your motor and electronics

11) batteries and battery clips.

that's all now you are ready to go

Step 1: Transmitter

make the circuit as shone in he above image

just copy the circuit as it is

it will definitely going to work.

Step 2: Reciever

just connect the data from the reciever module to pin no 14 on the ic. dont get confused

after completion it will look something like this .........which is shone in the above image.

Step 3: Use This Circuit to Convert 9-12v Vcc Into Regulated 5v

if you are giving 9v input to the circuit then u must use this circuit to convert it.

or if you are using 6v directly then no problem.

Step 4: Time for the Motor Driver

my drawing is not good

Step 5: Connect All the Patrs an Enjoyyy

you can use lipo batteries or laptop batteries too cause its too light weight

if you have any doubts, problem or any query leave it in the comments box

make your own and enjoy playing with your bot.
