7. Sprung Servo Crawler

Using a spring attached to a servo arm, I made a crawler. When pushing backwards, the spring would compress and "bounce" the crawler forward. When the spring then returned to its original position, the spring would bend and not affect the crawler (as much).

Before the video was shot, he was actually working much better. However, there were problems with getting enough friction as the crawler was used more and more. Troubleshooting was not particularly helpful.

I used the code that controlled the servo via serial: http://courses.ischool.berkeley.edu/i262/s11/sites/default/files/servo_control_serial.txt

However, since my servo is not the same as everyone else's, it has a different range: it only moves approx. 100 degrees instead of 180. Minor modifications were made to the code to prevent the servo from exceeding its boundaries.
