R2DC is the Washington D.C. (MD, DC, PA, VA) sub group of the worldwide R2-D2 Builders Club. We exist to share information and techniques on how to build the famous Astromech droids as seen in the Star Wars movie saga. These robots are accurate replicas of the movie props, featuring sound, lights and radio control for a realistic experience. There are twelve members participating locally who have built several droids (as well as other non-Star Wars robots) that visit conventions and charity events. Our robots are made from a variety of materials and most are radio controlled. Some of our builders have been experimenting with other means of operation i.e. microcontroller, Arduino and wi-fi. The robots range from fairly simple operation (rolling, head spin and sound) to more complex functions like changing from three-legged mode to two-legged mode or having doors open and close and objects popping in and out. Our club incorporates members from all levels of expertise from novice to engineers. We enjoy sharing our experiences and learning from each other.
