astromech droid R3-B9

Here is a collection of images from the making of my astromech droid R3-B9. It is made out of cardboard and some wood, featuring an Arduino Mega2560, and an Android app for the remote control via bluetooth. More details can be found on my blog https://mynewrobot.wordpress.com and R3-B9's first steps are documented on this video https://www.youtube.com/watch?v=3_FJEBKpF_s
