FYI, The 2015 MD Robotfest is this Saturday April 25th. The location is next to BWI airport. The Maryland Attack Group will be there with ships and tanks on display. If your in the area its a fun thing to do especially with the kids. There's always a Lego robotics display, 3d printers galore, and the R2D2 builders club is always a big hit with their lifesize versions of the iconic droids from Star Wars and Lost in Space. I'll be there with my tank, ship, and a secret project under development. Home | RobotFest
