Abstract
Motion planning is one of the fundamental tasks in robotics with the goal of producing feasible robot trajectories in configuration space that reach a desired goal optimally according to a given criterion. The principal purpose of this thesis is the development of novel high-dimensional motion planning methods that enable safe and efficient robot operation in real-world environments. We rely on trajectory optimization in order to produce robot trajectories that are smooth, collision-free and satisfy arbitrary task-dependent criteria. A common theme throughout this thesis is reliance on continuous-time Gaussian processes as trajectory representations that underpin efficient collision-checking and generate smooth robot trajectories. The thesis presents three scientific contributions: 1 A method for stochastic high-dimensional robot trajectory optimization based on cross-entropy and heteroscedastic Gaussian processes. 2 A high-dimensional trajectory optimization method based on stochastic gradient estimation using mixtures of Gaussian processes that enables inclusion of multiple complex criteria. 3 An incremental factor graph inference method for simultaneous moving object tracking and robot motion planning based on Gaussian processes.
Abstract (croatian)
Planiranje gibanja predstavlja jedan od temeljnih problema u robotici s ciljem generiranja ostvarivih robotskih trajektorija koje uspješno izvršavaju dani zadatak. Temeljni je cilj ove disertacije razvoj novih visokodimenzijskih algoritama planiranja gibanja koji omogućuju sigurno i učinkovito djelovanje robota u stvarnim, dinamičkim okruženjima. U radu se oslanjamo na metode optimizacije trajektorija kako bismo generirali glatke putanje robota koje nisu u sudaru s okolinom i zadovoljavaju proizvoljne optimizacijske kriterije. Oslanjamo se i na kontinuirane Gaussove procese za predstavljanje trajektorije čime je omogućena efikasna provjera sudara i postizanje visoke brzine izvođenja navedenih metoda. Tri su znanstvena doprinosa disertacije: 1 Metoda za stohastičku optimizaciju visokodimenzijske trajektorije robota zasnovana na unakrsnoj entropiji i heteroskedastičnim Gaussovim procesima. 2 Metoda optimizacije visokodimenzijskih trajektorija zasnovana na stohastičkoj estimaciji gradijenta korištenjem mješavine Gaussovih procesa koja omogućuje uključivanje više složenih kriterija. 3 Inkrementalna metoda zaključivanja na faktor grafu za istovremeno praćenje gibajućih objekata i planiranje gibanja robota zasnovana na Gaussovim procesima.
