I built a Chopping Machine that can chop vegetables for me because I'm lazy (?) It's built using an Arduino Nano, two Hitec servo motors and Actobotics™ from Servo City: https://www.servocity.com/ Chop broccoli, lettuce, tomatoes, carrots, zucchini, cucumbers. Just about anything really. Read more about how I built it on my blog: http://simonegiertz.com/blog.html FOLLOW ME ON TWITTER: http://bit.ly/1I4CrPy FACEBOOK: https://www.facebook.com/simonegiertz/
