Re: Line Tracking Times?
we had line tracking working well last year - and it took us about 5 seconds to get to the wall with it
we had 7 banner sensors on a bar about 2 feet wide.
funny thing is, the way we got our line tracking to work, we actually lost the line (went past it) which left the bot in a hard turn, and it would reacquire the line and then shoot up the ramp.
but we never used it in the competition. After we shipped the bot we realized it would be faster to use the gyro sensor, which we already had installed for closed loop steering, to integrate a compass heading, and to start off backwards and do a V turn.
this got our time to wall down to 3 seconds.
BTW - there was something about last years line following that made it very difficult - the half circle connected to a straight line requires accelerated acceleration to follow - in physics its called a jerk
the discontinuity from a straight line to a circle looks smooth, but its not. In fact, to follow the line perfectly last year would have required infinite acelleration (impossible)
and guess what, those bends in the line this year? same thing - you cant follow them perfectly, so your algorythm will have to take that into account - anticipate where you are going (straight, left turn, right turn....)
