We need help on our autonomous code. It does not follow the line in a straight manner. Our sensor set up is similar to the attachment.
The robot starts going straight, but then just keeps going back and forth between the outer most sensors until it is completely off the tape. We programmed the outer ones to be only 45's. Once off, it just spins in circles. We are sporting a two wheel drivetrain with casters on four corners of the robot.
We are also having problems with the 884's. Sometimes the motor speeds are different when set to the same value on the joysticks or program, resulting in it turning all the time. But when we set the motors to full forward or full back, the robot goes straight. We have calibrated the victors several times and replaced them at least three times. This is a problem because if we go to dead reckoning the robot will not go straight.
Our competition is on Thursday 3-11-04, Friday 3-12-04, and Saturday 3-13-04. So any immediate help would be greatly appreciated here or at the competition.
Thanks,
Sudeep - Team Frog Force (503)
