ohh, 5 inches might be pushing it Where did you get 5 inches from?Actually, sharp ir sensors might return different values from blue and white so it might be possible...
IF left sensor sees line( drive right)Else if right sensor sees line(drive left)Else(drive straight)
well, i take it your robot isn't going to be 5" from the ground?
I decided that I will use a cheap chassis from a toy car,instead of building a differential one.My concern is the turning radius in corners. I will try modifying the steering mechanism ie use a servo to turn.I think this would give me a bigger turn angle for the front wheels.
As for "line hug",what did you meant?
The Length of the track is 10 meters.How fast should I go? Dunno..I think something like 50cm/s would be great.
As for the car, I might drive it backwards.This should provide a better turn radius.
[...] photoresistors, I read that they are quite slow to respond, phototransistors are much better.What do you think?
Do you have access to small lenses (acrylic is fine) to focus light?
How do you figure that?If the front wheels turn a certain amount, it will have a certain turn radius, no matter which way it goes.
Well,consider the situation of parking.It's easier to park going backwards because you can point the back of the car more precise.I admit that the steering radius is about the same, it's about orienting the car.
