Experimental investigation of locomotion efficiency and path-following for underwater snake robots with and without a caudal fin
(Journal article; Peer reviewed, 2018)Over the last few decades, the robotics community has shown increasing interest in developing bioinspired swimming robots, driven by the need for more economical, more efficient, autonomous, highly flexible and maneuverable ... -
Experimental Investigation of Obstacle-Aided Locomotion With a Snake Robot
(Journal article; Peer reviewed, 2011)In a recent paper, the authors have proposed a control strategy for a snake robot during obstacle-aided locomotion. In this paper, experimental results are presented where the controller is shown to successfully maintain ... -
Experimental Investigations of an Icing Protection System for UAVs
(Journal article; Peer reviewed, 2019)UAV icing is a severe challenge that has only recently shifted into the focus of research. Today, there are no mature icing mitigation technologies for UAVs, except for the largest fixed-wing drones. We are working on the ... -

Experimental Monitoring of Sea Ice Using Unmanned Aerial Systems
(Master thesis, 2015)The exploration of arctic seas for offshore oil- and gas resources has received increasing interest the past few years. Despite the recent dramatic fall in oil prices, estimates indicate that as much as 22% of the worlds ... -
Experimental Results for Set-based Control within theSingularity-robust Multiple Task-priority Inverse KinematicsFramework
(Journal article; Peer reviewed, 2015)Inverse kinematics algorithms are commonly used in robotic systems to achieve desired behavior, and several methods exist to ensure the achievement of numerous tasks simultaneously. The multiple task priority inverse ... -
Experimental set-up of a thermal vacuum chamber for thermal model in-house correlation and characterization of the HYPSO hyperspectral imager
(Peer reviewed; Journal article, 2023)Space environment with changing temperatures and vacuum can affect the performance of optics instruments onboard satellites. Thermal models and tests are typically done to understand the optics performance within large ... -
Experimental study of installation procedure and volume estimation of tarpaulin for chemical treatment of fish in floating cages
(Journal article; Peer reviewed, 2017)In the salmon industry chemical delousing is done by enclosing the cage in a tarpaulin, and then mixing the chemical agent in the enclosed water volume. Correct dosage is important to obtain the wanted effect, and in order ... -
Experimental Testing of HeaveLock
(Master thesis, 2016)When drilling from a floating rig the ocean waves induces a vertical motion on the rig. This movement is called heave motion. During a connection, when the drill string is extended, the drill string is attached to the rig ... -
Experimental validation of attitude and rate-sensor bias filter using range-difference measurements
(Peer reviewed; Journal article, 2018)This paper considers the problem of constructing a filter for estimating attitude and rate-sensor bias, that has both proven stability and close-to-optimal performance with respect to noise. The filter is based on measuring ... -
Experimental validation of camera-based maritime collision avoidance for autonomous urban passenger ferries
(Peer reviewed; Journal article, 2023)Maritime collision avoidance systems rely on accurate state estimates of other objects in the environment from a tracking system. Traditionally, this understanding is generated using one or more active sensors such as ... -
Experimental validation of camera-based maritime collision avoidance for autonomous urban passenger ferries
(Peer reviewed; Journal article, 2023)Abstract: Maritime collision avoidance systems rely on accurate state estimates of other objects in the environment from a tracking system. Traditionally, this understanding is generated using one or more active sensors ... -
Experimental validation of dynamic stationkeeping capability analysis: The next level DP capability analysis
(Master thesis, 2012)This thesis considers two main issues: the theoretical aspects of stationkeeping capability analysis in general, and dynamic capability (DynCap) analysis in particular; further there has been conducted capability analyses ... -
Experimental Verification of a Coordinated Path-Following Strategy for Underactuated Marine Vehicles
(Journal article; Peer reviewed, 2019)This work presents the results of an experimental verification of a coordinated path following strategy for underactuated marine vehicles. The coordinated path following strategy is presented, and is then experimentally ... -
Experiments and modelling of near-horizontal bubbly flow
