becker.robots problem.

I really need help with this problem. I have tried alot of methods to do this but my attempts are just simply not good enough.

My problem is -

# TopSoil01.cty
# Window title
Spread Top Soil: Test Case
# first street, first avenue, num streets, num avenues
0 0 30 10
# intersection size
38

# There is a Robot that likes to garden. In the spring
# the Robot needs to spread topsoil in her garden beds.
# There is a large pile of topsoil in the intersection immediately
# in front of her. You may assume that there is more than
# enought topsoil. The topsoil is to be spread on the
# other side of a stone wall.
#
# Program the gardening Robot to spread the topsoil one wheelbarrow
# at a time on the East side of the wall. Unfortunately
# the Robot does not know how long the wall is to the left and
# to the right, and so it has to first determine how many steps there
# are to the left end of the wall and how many there are to the right.
# Having determined this, the robot will return to the pile of topsoil
# and begin to carry loads around the wall in the shorter direction.
# Of course, at some point, it will become a shorter trip for the robot
# if it takes a load in the other direction. Your program must determine
# this.

# Also note that the robot needs to stop taking loads when every
# location on the other side of the wall has had one pile of
# topsoil dumped.

#In your program, you must instantiate a Robot as shown below.

#becker.robots.Robot 8 2 Direction.WEST

#The garden wall
becker.robots.Wall 3 4 Direction.WEST
becker.robots.Wall 4 4 Direction.WEST

All i am asking is how about would you go thru with this problem. eg what loops will you use or how would you deal this with what steps.
I have been cracking this problem for about 5hours and i still cant figure this out. All help are greatly appreciate and Thank you for your time.
