(...) Well, I tried this, and it's hopeless. The RCX can't poll the sensor nearly fast enough, and even if it could you'd need a lens to focus the sensor better. (...) Instead of using my idea, I took the suggestion of someone else and just used a (...) (25 years ago, 30-Dec-99, to lugnet.robotics, lugnet.trains, lugnet.robotics.rcx)

(...) It's 2D, not 3D. It is pretty cool looking but more susceptible to damage than the 1D codes because the 1D codes are wide in the second dimension for redundancy. /Eric McCarthy/ (25 years ago, 30-Dec-99, to lugnet.robotics, lugnet.trains)

This is going to be tricky without real arrays. LegOS may be the only option. You'll be looking for a start symbol (maybe just one framing bit, sometimes a legal character in the barcode set and sometimes just a pattern). Once you identify it you (...)
