Hi,

I would like to control a small robot from my laptop wirelessly. To my understanding, I need to hook up some sort of antenna to RS232 and have a receiver on the robot to control that. Do any of you have more info on how exactly this is done? (like a dummy's guide on this thing) Should I use Visual Basic to make a graphical user interface for controlling this machine?


Now I think of it, the project may be too difficult for me. I will see what I can do.

Thanks alot

not just an antenna. you need wireless transceiver (FM/AM transceiver..). You can find them on rfsolutions.co.uk or other places. Interfacing to these transceivers is usually serial.

Yeah, that is what a meant. Transceiver. Obviously, a stick of wire soldered to RS 232 wouldn't do it.

Try going down to your local toy store and picking up the cheapest radio control car you can find (shouldn't cost your more than ten bucks) use it's control hardware instead of making your own or buyign something overly complicated for your task. Though you'd want to control it from a parallell port on your PC, rather than an RS232 port. Parallel ports already work at 5 volts TTL logic levels. Rs232 works at -24 to +24 (max, your milegage may vary)
