Vector Field Path Following of Static Sinusoidal Paths for Underwater Snake Robots
(Chapter, 2023)In this paper, a guiding vector field (GVF) approach is applied to solve the path-following problem of a static unbounded sinusoidal path for an underwater snake robot (USR) in the presence of constant irrotational currents. ... -
Vehicle Collision Avoidance System
(Master thesis, 2013)Thesis Description: The purpose of the thesis is to develop and simulate a collision avoidance system for a vehicle. Both static and dynamic obstacles should be considered. -
Vehicle Detection and Landing as an Addition to Package Delivery Drones
(Master thesis, 2019)De nylige utviklingene i autonome pakkeleveransedroner gir lovende resultater, men har potensiellt begrensninger når det gjelder maksimal avstand de kan dra. I denne oppgaven skal jeg ta for meg muligheten til å bruke ... -
Vehicle Guidance with Control Action Computed by a Rao-Blackwellized Particle Filter
(Chapter, 2017)Particle filters can be used in navigation and state estimation problems. They can approximate arbitrary posterior distributions and do not require assumptions of Gaussianity or linearizations. This paper suggests to use ... -
Vehicle Safety of the Velocity Obstacle Algorithm
(Peer reviewed; Journal article, 2020)This paper presents a mathematical analysis of the velocity obstacle algorithm applied to a nonholonomic vehicle for avoiding a moving obstacle in the plane. The velocity obstacle algorithm can be used for local navigation ... -
