This summer, the Robo Raven team designed a laser cut detachable claw to enable the Robo Raven to deliver Hogwarts letters a la Hedwig the owl from Harry Potter. Special thanks to Grant Wing for acting! All video production was done in house by Alex Holness and myself. This video was featured online in Popular Mechanics (http://www.popularmechanics.com/flight/a16719/solar-powered-robot-raven/).
