I think you misunderstood a bit.  You still use the Light Sensor as
discussed to get an approximate range, It'll never be great, All you use the
RCX's IR input for is to verify that the signal you recieved was the one you
sent out.

The two work together to solve the problem.

Yes, but even if that was posible it would give you no indication of distance. Eric -----Original Message----- From: Tim McSweeney [mailto:tim@ams.co.nz] Sent: Tuesday, January 12, 1999 6:31 PM To: lego-robotics@crynwr.com Subject: Re: simple but (...) (28 years ago, 13-Jan-99, to lugnet.robotics)
