TV remote controlled robot

The most cheapest way of controlling  the devises through wireless is IR remote.Every one in the world will have a TV remote which works based on RC5 protocol or some equivalent protocol.I searched over the internet for a perfect TV remote signal decoder compatible with all sensor like TSOP  and other cheep TV sensor.I all ways thought of making such TV remote signal decoder.

But recently i found a TV signal decoder in Hyderabad.compatible with all most all TV remotes except for DVD,AC remotes.Actually it is a handmade one.I found it in a hobby shop.I bought for 295 Rs. i made some modifications regarding the power supply for direct 5V Vcc to the decoder module.
This  one outputs a 5 bit address,6 bit data,a toggle bit and a valued data bit.
One important thing is the output form the decoder module will produce active low logic
if we press "2" on the remote the 6 bit data will be"111101"
if we press "4" on the remote the 6 bit data will be"111011"
if we press "0" on the remote the 6 bit data will be"111111"

I made a robot using that module.

I used a ATmega8 development board with ob board programmer for driving the motors as per the logic.
I removed the address pins on the decoder module and i connected the 6 bit address to the PORTC of ATmega8 and an L293D is used for driving motors which is internally connected to PORTD  higher nibble on the development board.
