Has anybody seen IR controls yet?

[Wayne Lundberg]

Has anybody seen anybody using infrared transmitter/receivers as a possible
replacement of RC?

One of the little micro cars out there uses IR. Problems are range and
the fact that they have to be in line of sight. Not a good replacement
for radio waves.

Probably wouldnt give good enough range. It'd be like your TV remote -
disappear round a corner and you'd lose it.

Not only that but using IR modules outdoors and under
certain man made lights is problematic at best.

I don't think IR would go very far for RC.

I doubt if infrared would work, the range is very limited ideal for use in
the home.

Thanks one and all. We had the same problem at the San Diego Robotics Club
when sunlight hit the walls at different angles. Just thought a directional
kind of device might have been developed to filter out all except the IR
frequency in both receiver and transmitter.
Or a laser capable of penetrating a shield on the receiving end.

IR has its uses, long range tend to be fixed systems though, say computer
connections to a central building without running wires. Home remotes
run off a small battery, if you are willing to haul a large transmitter then
you could have a decent system, though that would seem to involve
using many diodes in parallel. In theory you could use a filtered lamp
with an optical shutter.

Don't IR receivers have problems with direct and reflected sunlight?

Heheheh, my optical mouse would agree .. though that's not IR, in direct
sunlight it gets a little .. er .. jerky .. ;)

They usually work ok since the sun doesn't send out the encoded pulses
the receiver/decoder is looking for. If you want to see the pulses an
IR transmitter sends out, look at the front of a VCR, TV, etc. remote
with a video camera while pushing a few buttons. You can see the
pulses change frequency. Kinda neat.

Bzzzt .. Samsung .. ;) Though it does have opaque, 'see-through' sides.

The enclosed MS one _is_ way worse though .. ;)

I have no problems with my Logitech, and it's sensors point straight
up... of course it's a trackball with a locking ring around the ball,
but still ;)

Heh, couldn't get on with a trackball .. though I used to have a really
nice one on the old amiga, way, way back when .. ;)

ugh even worse, lasers would require perfect line of sight... just stick
with RF, theres nothing really better then it for this application.
