Sensors are divided into groups with two...
The Unmanned Airship Vehicle (UAV) has a massive ability for low altitude and low speed exploration and surveillance applications. In order to develop a blimp based on a small size, light weight, high level functionality and communications, the navigation system and autonomous embedded blimp system are presented in this paper. The low-weight components of a Gumstix computer-on-module running embedded...
