This weekend I created the YesNoBot - a simple robot that is able to nod and shake its head.

I used two servo-motors a bunch of cablebinders, an arduino and a sheet of paper to create the bot. I wrote some build instruction after the video


The servos get tied together using two cable binders as shown in the image below. I also used two brackets to stabilize the lower servo a bit. The head is cut from a sheet of paper and sticked to the upper servo using sticky tape.

cylinder bot

this drawing started out as a deployment-doodle - I continued to draw a cylinder every-time I had to wait for a buildfile to bake an ear or a webapplication server to deploy it.

At home I saw that the cylinders had a face and added some eyes and a little background
