I am creating an entry for a line following contest at an upcoming robotics
event and I am looking for ideas on how to design my robot. The models I
have built to date are based on a single light sensor but I have just
received a second light sensor and it seems to me I should be able to
produce a faster robot if it doesn't have to keep one sensor on the line but
can just keep the line in between the two sensors. If anyone has built a
robot designed to follow a path as quickly as possible I would love hear
about it.
Thanks,
Scott

| (...) just program your robot to turn the opposite way as the sensor that goes off the line. i made a line tracker with one light sensor that had treads instead of wheels. when it got off the line, it started roving back and forth (more and more (...) (25 years ago, 24-Aug-99, to lugnet.robotics)

| (...) I've built both (single and double sensors). You're going to have to play with the design of your robot. The programs are fairly quick, but if your bot starts swinging back and forth, the light sensor might not pick up the line all the time. (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

| (...) Depending on the width of the line, you might be better off if you can keep both sensors on the line. That way there is a distinction between being on the line and being way off. If you find yourself way off, you can go searching back and (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

| This is mainly for people who still want to stick to just one light sensor -- You can still figure out which way to turn even with just one sensor, by following the edge of the line rather than trying to follow the center. This works only if your (...) (25 years ago, 25-Aug-99, to lugnet.robotics)
