I'm not sure how feasible this would be, but has anyone considered making a digital camera using the light sensor? All you'd need is a focusing mechanism with lenses/mirrors, and a couple of motors to scan left to right and up and down. Sounds easy (...) (25 years ago, 9-Feb-99, to lugnet.robotics)

(...) I nominate a Lego "assembler" as an "ultimate" project for a RCX (or more likely a group of RCXes with a PC). I've seen a few Lego brick sorters, an assembler seems like a logical next step. Once you have all those bricks programmatically (...) (25 years ago, 10-Feb-99, to lugnet.robotics)

Hi, yes, I actually had the same idea: use the light sensor on a robot as a crude mobile low-quality camera, which sends back scan-lines to the PC via datalog. however, thinking about the needed IR transmission and the line-of-sight precondition (...) (25 years ago, 11-Feb-99, to lugnet.robotics)
