A novel automatic UAV launcher design by using bluetooth low energy integrated electromagnetic releasing system

This paper presents a novel state of the art catapult launcher system designed for small size unmanned aerial vehicles (UAVs) by using a bluetooth integrated electromagnetic feedback system and provides in depth know-how on the design, fabrication, structural test and software implementation. Whereas the launcher uses a spring as the primary energy source, its carriage uses the electromagnetic energy to hold and release the UAV. First, the novel design and its implementation are briefly explained. Second, the working principle of the electromagnetic releasing system as well as data acquisition of the launcher by using ultra sonic and pressure sensors are given. The real time test results show the efficiency of the novel and cost effective design.
