For cheapness the following probably can't be beat: http://www.mop.no/~simen/legoproxi.htm ($free) otherwise you can buy IR proximity sensors based on reflected IR: http://www.hitechnicstuff.com/IRpage.htm ($40) http://www.techno-stuff.com/DIRPD-T.htm ($34) http://www.geocities.com/mindsensors/IRROD.htm ($14) or a sonar range sensor: http://www.hitechnicstuff.com/URpage.htm ($80) or a brick that interfaces to the Sharp GP2D12 IR sensor that measures absolute distance from about 10cm to 80cm (YMMV): http://www.geocities.com/mindsensors/gp2d12.htm ($41) I only have experience with the last, which works nicely after some careful calibration (Nitin has been very responsive to my questions!) Also check http://www.alynk.com/usr/gasperi/lego.htm to see what home-brew proximity sensors various folks have come up with. - Gareth

Hi all. I want play with my RCX this Christmas so I have thought about building a proximity sensor. So guys, do you have any ideas?. I prefer simple and cheap solutions. Bye. (23 years ago, 19-Dec-01, to lugnet.robotics)
