RF modules

Hello,

I am wanting to make it so that my robot has the ability to be controlled from my lap top. I was wondering if using the parallax RF modules and this could connect the two, and make them talk.

Thanks for the input...

Nelson

    hello,

    I guess no one has used those before! Can anyone suggest another way of having my bot communicate with my computer at approx. 100ft of distance?

    Thanks,

    Nelson

    I believe there is a programming module that lets you do this over a distance. Check out www.parallax.com.

    The EB500 Bluetooth has an open range of 300 feet.

    ya it is not the module it self that I am having difficulties with it is the means that I need in order for it to connect to my computer.

    I like the look of the bluetooth module! Now just how would I connect it to my computer?

    With an EB600 adapter.

    If you have two BS2s...
    I recently did a simple proof of concept using the serial port on my BOE-Bot and Visual Basic 6. I got the idea from a N&V column somewhere on this site. VB writes to and receives from the serial port to a BS2. I didn't, but I'm convinced that adding RF output to the stamp is easy enough--the guys here will hardly let you fail.

    PC to BS2#1 to RF ---> to BS2#2 on robot

    VB5 Express was free at MSN a few months back, with luck it still is.

    HTH,

    Mark,

    ·· I cannot tell...Is the comment about two BS2s a reply to the question of connecting the second EB500 to the computer?· Because with an EB600 you do not need the BS2 or programming board.· The EB500 plugs directly into the EB600 which plugs directly into the computer serial port.

    Chris, Nelson--
    I'm new to everything and forget others aren't likely to follow my train of thought over days and multiple posts. I'll try to be more specific in the future.
    No, my post was in answer to Nelson's original inquiry-- how to issue commands from laptop to robot.

    Creating a wireless link from a PC to a Stamp for sending Serial Commands is quite easy... Here is a great tutorial... http://www.rentron.com/Stamp_RF.htm

    Note that the RF devices here have limited range, but are also really inexpensive...· You can substitute more powerful RF devices to get a longer range... Also, check out Sparkfun.com for some good info and wireless devices.
