Two Servo Crawler

Assignment: Servo Motor: Actuation Assignment 2

Collaborators: michael_lee

Description:

Used 2 servos to create a crawler. From this assignment, I discovered that it really is a difficult challenge to make something that can crawl. There are a lot of challenges involved, and throwing more motors at the problem doesn't quite solve the issue exactly.

Thanks to Michael for letting me borrow his servo for this assignment!

Components used:

Invisible tape

2 erasers

2 servo motors

Code used:

I used the code posted on the course website for a 2 potentiometer servo system.

This implementation generally works by "pulling" itself forward, putting both legs forward and then pulling back in something like a rocking motion.
