Automatisk Trimix blandesystem
(Master thesis, 2008)I forbindelse med dypere dykking er det behov for annen pustegass enn vanlig luft. En gassblanding bestående av nitrogen, oksygen og helium, kalt trimix, benyttes. Vanlig måte å lage denne blandingen på er ved å fylle en ... -
Automatisk Vanningssystem for potteplanter
(Master thesis, 2021)I denne oppgaven blir det designet et automatisk vanningssystem, og en fungerende minimums-implementasjon blir laget av systemet. Det gjøres et Litteratur- og Teoristudie relatert til vanningssystemer, planter og jord. ... -
Autonom retur og dokking av AVR robot
(Master thesis, 2017)\textbf{Batterimonitorering}: Det ble satt opp en spenningsdeler mellom batteripakken og mikrokontrolleren sin analog til digitalkonverter slik at batteriets spenning ble nedjustert til den interne spenningsreferansen som ... -
Autonom-robot med LIDAR-sensor
(Master thesis, 2018)En robot ble ferdigstilt etter utgangspunktet fra prosjektet TTK4551, høsten 2017. Denne ble laget til å fungere på linje med resten av robotene i NTNUs LEGO-robot prosjekt. Deretter ble den ene sensoren på roboten byttet ... -
Autonomous Aerial Ice Observation
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:291, Doctoral thesis, 2014)This work is concerned with autonomous aerial ice observation. Ice observation is a supporting activity in cold regions marine operations that are disturbed by various ice features. This supporting activity is motivated ... -
Autonomous Aerial Ice Observation for Ice Defense
(Journal article; Peer reviewed, 2014)One of the tasks in ice defense is to gather information about the surrounding ice environment using various sensor platforms. In this manuscript we identify two monitoring tasks known in literature, namely dynamic coverage ... -
Autonomous Aerial Recovery: Fixed-wing UAV Ballistic Airdrop and Deep-Stall Landing
(Doctoral theses at NTNU;2020:61, Doctoral thesis, 2020)Although human beings don’t have wings, it is often very useful to fly. Or at least to use the air to transport objects. Sometimes these objects have to be delivered on normally unreachable places under difficult conditions, ... -
Autonomous ballistic airdrop of objects from a small fixed-wing unmanned aerial vehicle
(Peer reviewed; Journal article, 2020)Autonomous airdrop is a useful basic operation for a fixed-wing unmanned aerial system. Being able to deliver an object to a known target position extends operational range without risking human lives, but is still limited ... -
Autonomous Bicycle
(Master thesis, 2010)The autonomous bike was conceived by Jens G. Balchen back in the eighties, and later picked up by Amund Skavhaug. The idea of a two-wheeled, self-powered, yet riderless bike has since been pursued intermittently over the ... -
Autonomous Bicycle: The First Self Balanced Ride
(Master thesis, 2011)The idea of an autonomous bicycle originates from Jens G. Balchen who wanted to make an unmanned autonomous bicycle. The idea was picked up by Amund Skavhaug who extended the idea with the concept of using an inverted ... -
Autonomous Cave Exploration using Aerial Robots
(Chapter, 2021)In this paper we present the complete system design for an aerial robot capable of autonomous exploration inside natural cave environments. Cave networks involve diverse and complicated topologies, complex geometries and ... -
Autonomous COLREGs-Compliant Decision Making using Maritime Radar Tracking and Model Predictive Control
(Chapter, 2019)This paper addresses the challenges of making safe and predictable collision avoidance decisions considering uncertainties related to maritime radar tracking. When a maritime radar is used for autonomous collision avoidance, ... -
Autonomous contact-based thickness measurement from a multirotor UAV
(Master thesis, 2019)Denne avhandlingen undersøker automatiseringen av tykkelsesmålinger ved hjelp av en ultralydssonde montert på en drone. Bruk av ubemannede luftfartøyer (unmanned aerial vehicles (UAVs)) for ikke-destruktiv testing ... -
Autonomous Distributed 3D Radiation Field Estimation for Nuclear Environment Characterization
(Chapter, 2021)This paper contributes a method designed to enable autonomous distributed 3D nuclear radiation field mapping. The algorithm uses a single radiation sensor and a sequence of spatially distributed and robotically acquired ... -
Autonomous Docking Control System for the Otter USV: A Machine Learning Approach
(Master thesis, 2020)Denne masteroppgaven utforsker muligheten for å bruke dyp forsterkende læring (eng. deep reinforcement learning, DRL) til å utvikle et autonomt dokkingsystem for en underaktuert overflatefarkost. Autonome marine fartøy er ... -
Autonomous docking using direct optimal control
(Journal article; Peer reviewed, 2019)We propose a method for performing autonomous docking of marine vessels using numerical optimal control. The task is framed as a dynamic positioning problem, with the addition of spatial constraints that ensure collision ... -
Autonomous Drifting of a 1:5 Scale Model Car
(Master thesis, 2011)Current automotive safety systems restrict the vehicle to the linear region of operation where the sideslip angle is small. Recent research in the field has discovered that drifting possesses unstable equilibria in which ... -
Autonomous Drilling Using Reinforcement Learning
(Master thesis, 2021)Prosessen bak brønnboring krever store investeringer. Optimalisering av operasjonelle parametere med den henskikt å maksimere borerate(eng:rate of penetration (ROP)) er derfor et naturlig diskusjonstema. Optimalisering av ... -
Autonomous driving of a small-scale electric truck model with dynamic wireless charging
