IMPROVEMENTS:            DRIVE RATIO:I felt that with more time i could have stayed with the higher drive ratio (115:1).The benefits would be that it would certainly run through the maze faster and also that the batteries would last longer as the effort required to run the robot would be reduced.WHEELS:I believe that changing the the size of the wheels could have an advantage and make the robot faster.Having smaller wheels would reduce the strain on the drive system on initial starting and be more responsive to quicker cornering.DRIVE HEIGHT:Having a lower centre of gravity would defintely be advantagious.Cornering faster would not be a problem.Mounting the Battery Boxes lower would be part of lowering the height and therefore the gravity would be lowered even more...
