What's not to love about a robot building a birdhouse? This one's for the . . . birdhouse? Ph. D. students Ben Cohen (University of Pennsylvania) and Mike Phillips (Carnegie Mellon University), along with research engineer Ellis Ratner (RobotWits, LLC) teamed up to create a video demonstration at CMU's Robotics institute on autonomous robot assembly — in this case, how a flexible automation model builds a birdhouse and what specifically goes into it (naming the video "Project Birdhouse: Autonomous Robot Assembly: Robot with a Nailgun!" was just icing on the cake).
