Different variants of robots are made known to humans. Mobile robots or mobots were discovered a few years back and became an interest for technologists and engineers.

Three swarm behaviors were explored in this study, namely, aggregation, foraging and formation. The researcher explored two methods to realize the said behaviors. The first method is the derived swarm behaviors from two dimensional swarm methods. The second method is by approximating swarm members as fluid particles and using smoothed particle hydrodynamics method. The testing platform is consists of nano quadrotors which will serve as the boids. These quadrotors are equipped with orientation sensors such as accelerometer and gyroscope. The quadrotors are also equipped with pressure sensor which generates the altitude reading of the robot. Two microcontrollers are utilized by the robot to execute and facility wireless communication, sensor fusion and motor control. Another part of the testing platform is consists of external observer which is realized by using a motion capture system. The motion capture system is composed of cameras which detects infrared light. The robots are equipped with reflectors of infrared light which is then detected by the motion capture system. The aggregation behavior in SPH using plane container yielded 84.88%. On the other hand using a spherical container, the accuracy is around 95.23%. Lastly using a toroidal container, the accuracy produced is 92.44%. Increasing the number of swarm elements or particles decreases the accuracy or aggregation of the elements in the aggregation point. Since every element is constrained by the container, convergence at the gravity point is not possible. Furthermore, increasing the number of particles will generate higher sum of particle distance from the point of aggregation. The reason for this is that a particle occupies space in the container and would likely add up to the distance from the gravity source of other particles. 2015-01-01T08:00:00Z text https://animorepository.dlsu.edu.ph/etd_doctoral/429 Dissertations English Animo Repository
