Last March RS Components, in collaboration with RobotChallenge, launched the Hack the Arduino Robot competition.
Jacob Glueck submitted a great hack for the Arduino Robot:
“A couple of years ago, I built an Arduino-powered shirt-folding machine which folds clothes. Using the Arduino robot from the RobotChallenge, I will build a device to remove folded clothes from the machine and to stack them. My idea is special because it will involve two Arduinos (the Arduino Uno in the shirt folder, and the Arduino Robot) which will have to communicate, and because it will be very useful. The robot will solve the real life problem of laundry folding by making the task easier and faster and by doing so nicely; the robot will use a custom-designed gripper to transport garments while keeping them perfectly folded.”
On his blog you can look at the pictures of the construction phase , and below watch the video of the final project:
