Servo Motor: Actuation Assignment 2

Lab 7: Servo Cradle

Submitted by m-craig on Tue, 03/19/2013 - 15:38

For this lab, I wanted to create a simple motion that both rocks the "cradle" (made from a paper clip box) atop the servo motor and moves it slowly around the room.  My (perhaps fuzzy) inspiration was to create a cradle that could rock a baby to sleep without confining him/her to the same area of his/her room all night.  Perhaps this could help acclimate small children to movement and change; or perhaps the movement would just create gentle breeze effects to help the baby fall asleep.

In this assignment I have built Mr. Crawls - a rectangular spider who is able to jump forward to catch his prey!

Chopstick Crawler (Servo Motor)

Submitted by Jenton on Sun, 03/17/2013 - 22:11



My chopstick crawler awkwardly ambles its way forward using a chopstick with a weight attached to one end. Not exactly sure why it works, but it does, and I'm leaving it at that.

We used a small servo motor to built a robotic crawler inspired by the flagellum of single cell organisms. This was our first robotics project and was constructed within 2 hours and 40 min.

Lab submission 7 - Crawler

Submitted by stlim on Sat, 03/16/2013 - 19:12


This work has been done in a group of Taek and Chan to use two servo motors.


Using two servo motors, a crawler is implemented. An eraser cut in half was used for the two legs. A processing code receives inputs from a gamepad and signals the arduino crawler.


The legs imitate human knees so each is fixed when it pushes the crawler forward but flexible when it restores. The two legs operate alternatively.
