We are planning on solving a physical maze (ie cardboard or plywood.) The plan is to use LegOS to allow C (NQC) capabilities. We haven't started on the physical part yet; instead we are concentrating on developing a working algorithm for solving (...) (25 years ago, 4-Oct-99, to lugnet.robotics.rcx)

I've looked at a couple of traces and it looks like the serial driver just stops receiving data after a certain point. One theory is that something happens (framing error or overflow), which then keeps the driver from relaying more information. I've (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.nqc)

Does anyone know anything about the RCX being used to solve maze problems? I am doing this for a school project, and I wanted to know if there is any information out there about it. Thanks, Eric (25 years ago, 3-Oct-99, to lugnet.robotics.rcx)
