Servo Motor: Actuation Assignment 2

I approached this assignment with the idea that we should be able to move the motor like a turtle in the lego programming laguage. I was successful in make the motor go forward and backward but the problem is that since goes in both direction it doesn't have a rewind and the range of movement is very small. I would like to try this with two servo motors which would also allow us to turn right and left. 

The code I used is given below

I made a crawler with a little fabric case. I tried other smaller boxes, but the boxes itself were rotated and stood up instead of lifted and moving. I found that a little bigger and heavier one containing the servo motor in one corner keeps it's orientation and moves horizontally because of gravity.

Material

Servo motor,

Acrylic + Museum Board for Leg

Strings for joining the motor and leg

Fabric case

Here is a video.

I've spent way too long trying to make a two-legged walker with a second servo I liberated from the TUI cafe, and that's really difficult!  So instead, here's my backup, a much lamer play-doh container sloucher -- not really a walker or a crawler.  It's the code from the lab, controlling the servo with the potentiometer back and forth.  The lid is attached to the servo and slightly unbalanced, making back and forth motion translate to side-to-side and slightly forward motion.  The cup stabilizes the apparatus.

Description
I used a servo motor and attached two bent paper clips to act as legs. Here is a demo http://www.youtube.com/watch?v=sk3_-OZ61jk
