The main contribution of the module is a custom-designed force/torque sensor based on strain gauges, which ... -
A Multi-Modal Approach for Hand Motion Classification Using Surface EMG and Accelerometers
Fougner, Anders Lyngvi; Scheme, Erik; Chan, Adrian D. C.; Englehart, Kevin; Stavdahl, Øyvind (IEEE Engineering in Medicine and Biology Society. Conference Proceedings;6091054, Journal article; Peer reviewed, 2011)For decades, electromyography (EMG) has been used for diagnostics, upper-limb prosthesis control, and recently even for more general human-machine interfaces. Current commercial upper limb prostheses usually have only two ... -
A Review of the Current Challenges Associated with the Development of an Artificial Pancreas by a Double Subcutaneous Approach
Christiansen, Sverre; Fougner, Anders Lyngvi; Stavdahl, Øyvind; Kölle, Konstanze; Ellingsen, Reinold; Carlsen, Sven Magnus (Journal article; Peer reviewed, 2017)Introduction Patients with diabetes type 1 (DM1) struggle daily to achieve good glucose control. The last decade has seen a rush of research groups working towards an artificial pancreas (AP) through the application of a ... -
A review on modelling, implementation, and control of snake robots
Liljeback, Pål; Pettersen, Kristin Ytterstad; Stavdahl, Øyvind; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2012)This paper provides an overview of previous literature on snake robot locomotion. In particular, the paper considers previous research efforts related to modelling of snake robots, physical development of these mechanisms, ... -
A Sensor Calibration and Sensor Fusion Approach with Focus on Tactile Force Estimation for Perception-Driven Obstacle-Aided Snake Robot Locomotion
Fredriksen, Vetle Bjørnstad (Master thesis, 2018)Snake robots have been a research topic of interest since Shigeo Hirose developed the first snake robot in 1972. As with many other types of robots, snake robots are interesting because they could be used to perform tasks ... -
A Sensor Fusion Approach with Focus on Visual Sensing for Perception-Driven Obstacle-Aided Snake Robot Locomotion
Kjørholt, Harald Gard Halvorssønn (Master thesis, 2018)Developing snake-like robots can be advantageous for numerous reasons. Biological snakes are capable of traversing all types of terrain in a very energy efficient and effective way. They achieve this variety of locomotion ... -
A simplified model of planar snake robot locomotion
Liljeback, Pål; Pettersen, Kristin Ytterstad; Stavdahl, Øyvind; Gravdahl, Jan Tommy (Chapter; Peer reviewed, 2010)This paper presents a model of the kinematics and dynamics of a planar, wheelless snake robot aimed at control design and stability analysis purposes. The proposed model is significantly less complex than existing models ... -
