 | | New RCX sensor: Wire guidance sensor
|
|
Inspired by vehicles moving precisely along the roads in Miniland, I have created this homebrew sensor, which allows a RCX robot to follow a wire track. Since distance between sensor and wire can exceed 1 cm, the wire may even be hidden below (...) (21 years ago, 6-Jan-03, to lugnet.robotics)

very good application-idea Philippe, and nicely implemented ! Looking at your idea, brings me on another idea. Shouldn't it be possible to build another wire-follower, consisting of just 1 wire, fed by a DC source and a measured with a Hall-sensor? (...) (21 years ago, 6-Jan-03, to lugnet.robotics)

(...) Maybe John Barnes would be interested in doing something with this? One other question - do you have any idea how long can the wire can be with the AC generator you built? Regards ROSCO (21 years ago, 6-Jan-03, to lugnet.robotics)

This is beautiful! I, too, have been inspired by the cars driving around Legoland (though in California and Denmark) but my solution has been to use the light sensor on a visible track. It occures to me that it would be very easy to adapt your (...) (21 years ago, 7-Jan-03, to lugnet.robotics)

Hello Stef, (...) Thanks ;o) (...) That might work, but getting a high enough field to be detected and be immune to external sources (including earth magnetic field!) would require a LARGE current, not very practical... Philo www.philohome.com (21 years ago, 7-Jan-03, to lugnet.robotics)

Hi Rob and Ross, (...) Sorry, I have neither time nor structure to do that... (...) I hope so ! (...) I have not tested that (my longest track is about 5 meters), but as actual current is fairly low I think that wire can be quite long. I used thin (...) (21 years ago, 7-Jan-03, to lugnet.robotics)
