Abstract

Robot swarming, increasingly find importance in the last decade. In these systems, multi mobile robots have to work cooperatively to perform specified tasks. One of the compelling problems is that the robots movements should be in such a way that they should follow a specific guide and at the same time they should have the ability of obstacle avoidance. Inspiriting such movement from biological swarms is a compelling problem. Fish schools, bird flocks and sheep herds are particular examples of biological systems swarming. In this paper, a robot swarming algorithm was developed based on swarming rules noticed in these biological systems, the combination between the swarm members and the leadership control also explained, an ad-hoc non-essential communication system was proposed for the purpose of use in case of collective takeoff and collective landing swarm-robots, in which activated automatically.

Abstract

The research proposed a new electrically reconfigurable microstrip antenna via a lumped capacitor. Instead of using a varactor diode as a switching circuit which leads to a more complicated design by adding biasing circuits, our suggested antenna design has offered straightforward tuning skills. The projected design has resolved many issues such as a reduction in system complexity by eliminating the biasing circuit, limiting the use of advanced manufacturing devices through using the external circuit to implant or detach the capacitor into or from the antenna main structure, and impedance matching supported with optimum physical structure calculations. The reconfigurable antenna has been modeled and designed using computer simulation technology (CST) software, the prototype antenna has been implemented practically and tested using a spectrum analyzer. The suggested compact antenna has a size of 42×33×0.53 mm3, and supports multi-operational frequency bands (C, X, Ku, and K) which is suitable for modern communication technologies such as Wi-Fi, 5G, and satellite communication.
