Collision avoidance of UAV is an important function required from pilots and traffic controller as it intends to fly in the airspace of manned aircraft. It is implemented into Smart UAV which the flight test for automatic take-off, conversion and mission flight was conducted successfully last year. Prior to flight test for collision avoidance, the hardware-in-the-loop simulation (HILS) test is conducted...
Despite the rapid increase in demand for non-silicon solar cells, which represent the next generation of solar cell technology, silicon solar cells still dominate the market. Silicon solar cells can be roughly divided into two types: silicon wafer and silicon thin-film. Silicon wafer solar cells are helping to expand the solar cell market by enhancing efficiency and cost competitiveness, while silicon...
This paper describes an unmanned autonomous helicopter system developed by KAIST UAV team. The developed RUAV (Rotary-Wing Unmanned Aerial Vehicle) system consists of the guidance and control system for autonomous flight, ground control system (GCS), mission payloads, and communication system. The implemented autopilot in RUAV has four control channels for longitudinal and lateral velocities, altitude,...
