Video Friday: Printable Hydraulic Robots, Medical Delivery Drones, and Romeo Walks

Video Friday is your weekly selection of awesome robotics videos, collected by your fluid-filled Automaton bloggers. We'll also be posting a weekly calendar of upcoming robotics events for the next few months; here's what we have so far (send us your events!): Let us know if you have suggestions for next week, and enjoy today's videos. MIT has developed a 3D printer that can mix solids and liquids. With "printable hydraulics," an inkjet printer deposits individual droplets of material that are each 20 to 30 microns in diameter, or less than half the width of a human hair.
