We love robots, DIY and funny science. jjRobots aims to bring Open robotic projects closer to the people by providing hardware, good documentation, building instructions+code, "how it works" info and a lot of fun!
BlimpDuino 2 is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board WIFI and laser sensors. Two vectoring (tilting) differential thrusters and one lifting propeller. Simple but exciting ;-)
