USE A REMOTE CONTROL in robotics... help us

Hi we are two students in a swiss technical school. we are making a
projet with the Boe-Bot from parallax (with basic stamp2). we have a
big trouble : we want to use the frequencies from a tv remote
control, but we arent able to recover the frequencies and to use it.
PLEASE HELP US !!!!!

underwrote it, so I'd imagine it is somewhere on the Parallax site, but I
didn't see it off hand.
The idea is to use an integrated IR receiver to demodulate the remote
control. Then the only other problem is the speed of the Stamp. What I did
was use PULSIN to read a "word" and then check for the sync pulse at the
start. If I didn't get a sync pulse, I'd start over. Eventually you will
sync up.
However, one issue. Since the Stamp can't listen to the IR and drive the
remote at the same time, it is difficult to implement logic like:
Push button #1 and release
Motor spins
Push button #2 and release
Motor stops
What I did was something like this:
Wait for button push
If button was #1, spin Motor for 50mS
. . .
Loop
So the idea is that you push a button and hold it and the robot moves. When
you release the button, the robot stops. Different buttons cause different
motion. Otherwise you get into the problem of the motors not turning while
the PULSIN command times out and/or the IR not responding while the motors
are turning.
Hope that helps.

I'm not sure if this is what you want, but this page shows how to make a
device that uses a universal TV remote to talk to the Stamp. You can see it
at:
http://madlabs.info/ir_remote.shtml
This project use the Sony protocol. While the project uses a PIC, I think
the code could easily be changed to run on a Stamp. We have been using this
device on our Stamp based fuel cell robot to operate the robot.

If you're not using similar IR components, it will at least give you some
insight on how it's done with the Stamp.
