• Geometric Reduced-Attitude Control of Fixed-Wing UAVs 

      Coates, Erlend M.; Fossen, Thor I. (Peer reviewed; Journal article, 2021)
      This paper presents nonlinear, singularity-free autopilot designs for multivariable reduced-attitude control of fixed-wing aircraft. To control roll and pitch angles, we employ vector coordinates constrained to the unit ...
    • Locomotion efficiency optimization of biologically inspired snake robots 

      Kelasidi, Eleni; Jesmani, Mansoureh; Pettersen, Kristin Ytterstad; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2018)
      Snake robots constitute bio-inspired solutions that have been studied due to their ability to move in challenging environments where other types of robots, such as wheeled or legged robots, usually fail. In this paper, we ...
    • Perception-Driven Obstacle-Aided Locomotion for Snake Robots: The State of the Art, Challenges and Possibilities 

      Sanfilippo, Filippo; Azpiazu, Jon; Marafioti, Giancarlo; Transeth, Aksel Andreas; Stavdahl, Øyvind; Liljebäck, Pål (Journal article; Peer reviewed, 2017)
      In nature, snakes can gracefully traverse a wide range of different and complex environments. Snake robots that can mimic this behaviour could be fitted with sensors and transport tools to hazardous or confined areas that ...
