(...) It's even more than that really. Sending live video over IR really isn't feasible - there isn't anywhere near enough bandwidth to do that. What you *REALLY* want is to have enough on-board CPU power in the robot to process the images locally - (...) (22 years ago, 4-Jan-03, to lugnet.robotics)

(...) "All ideas are stupid until someone proves they work." :D No, I've been thinking the same thing. (So it can't be stupid haha). A PDA with built-in webcam (and mike) + hotwiring an RCX input to a serial port on the PDA would probably be the (...) (22 years ago, 5-Jan-03, to lugnet.robotics)

Speaking of PDAs, specifically Pocket PC's, the HP iPAC 5450 has Consumer IR, will that automatically take care of the comm thing with the RCX? Then I guess that would be ideal, tho expensive ($700 in Sweden). But that's provided there is a (...) (22 years ago, 6-Jan-03, to lugnet.robotics)
