Need help with building a Cam interface circuit for a school project

i am building a small robot. i have all the things i need to make it "alive", but he is "blind", because i dont know how to build a circuit that can transmitt the data from the cam to a normal tv.

and i need help with a receiver for the data transmitted by the cam.

please help me.

My Jameco catalog has a 2.4 GHz wireless color tv camera for $90.00. The receiver runs $124.00. That gives you a 150' range. Doubt if you can beat the price as a DIY project.

thanks j.p.bill for the info but i am trying to build a very low low cost robot.

That is low cost!. You can buy specific 2.4GHz transmit and receive modules, but would still need a camera, which was included in the costs above.

BTW - the 2.4GHz wireless links use the same frequencies as WiFi, so don't work (more than a couple of feet) if you have a WiFi network.
