“…Compared to the downlooking approach, the advantage of a side-looking radar is the increased area throughput and the lower ground reflections. In [11], different UASs designed for military applications in combination with a side-looking GPR are investigated for mine detection. However, due to the low altitude required to detect landmines with a GPR and the high material and financial risk associated with this type of UASs, the approach was considered impractical.…”

Anti-personnel fragmentation mines are relatively large metallic mines, which are only partially buried and often triggered by a metallic tripwire. In humanitarian mine clearance, the search for the wires is usually carried out manually. As a new approach, an airborne system for the detection of tripwires using a synthetic aperture radar is presented. The system consists of an industrial multicopter, a frequency-modulated continuouswave radar, and a real time kinematic global navigation satellite system. For image formation, a back-projection algorithm is used. Measurements with tripwires attached to a dummy mine successfully demonstrate the functionality of this system approach. In addition, the influence of wire length, vegetation, and incidence angle are investigated. It is shown that several overflights with different directions of flight are required to detect randomly oriented tripwires.

“…These applications can range from the agro-industrial sector and the conservation of natural resources [3,5,8,9,13], as in search and rescue or in disaster prevention tasks, [7,18], or applications to support sustainable urban development, such as those developed by [1,14]. Another important application is the search and deactivation of antipersonnel mines, such as those mentioned in [2,10,12].…”

This paper presents the development of a cooperation scheme among unmanned aerial vehicle (UAV). Sliding mode control technique is used to guarantee that the set of robots can follow a reference trajectory and, in addition, will guarantee collision-free navigation of these autonomous vehicles. The analytical approach of the control strategy is shown, and the necessary conditions to guarantee the stability and governability of the multi-robot system are derived. The strategy and the derived conditions are tested using simulations, to demonstrate their effectiveness for collision-free navigation of an UAV fleet.

“…Several research and application projects have been developed based on the capabilities of an unmanned aerial vehicle (UAV). From agriculture [1] to noninvasive landmine detection [2], the wide range of disciplines impacted by these aircrafts is impressive and increasing. However, the performance of the UAV is determined by the effectiveness of the automatic control algorithm implemented in it, which allows the vehicle to develop a specific required task.…”

A methodology for the experimental modelling of the electric actuators of a multirotor is presented in this work. These actuators are usually brushless DC motors which are driven by electronic speed controllers in an open loop. The duty cycle of a PWM signal, generated by the electronic control unit, is the input of the electronic controller. However, during the control design procedure for the multirotor, it is important to account with a model of the actuators as its dynamical features define the closed-loop performance of the overall aircraft. Hence, a procedure, based on low-cost electronic components, to obtain approximated transfer functions of the actuators of a multirotor is presented. Moreover, as the proposed signal processing algorithms are simple, the computational capabilities of the required embedded system are also low. Given that different control schemes require different information from the actuator, two models were obtained: a duty cycle vs. angular velocity transfer function and a duty cycle vs. consumed current transfer function. The effectivity of the proposal is validated with experimental results on common electric actuators of a multirotor.
