    • Body Shape and Orientation Control for Locomotion of Biologically-Inspired Snake Robots 

      Rezapour, Ehsan; Pettersen, Kristin Ytterstad; Gravdahl, Jan Tommy; Liljebäck, Pål (Biomedical Robotics and Biomechatronics;5th IEEE RAS/EMBS International Conference on Biomedical Robotics and Biomechatronics, Chapter, 2014)
      This paper considers guidance-based motion control of planar snake robots using a dynamic feedback control law. We first present the Euler-Lagrange equations of motion of the robot. Subsequently, we introduce a dynamic ...

    • Differential Geometric Modelling and Robust Path Following Control of Snake Robots Using Sliding Mode Techniques 

      Rezapour, Ehsan; Pettersen, Kristin Ytterstad; Liljebäck, Pål; Gravdahl, Jan Tommy (Journal article, 2014)
      This paper considers straight line path following control of wheel-less planar snake robots using sliding mode techniques. We first derive the Poincaré representation of the equations of motion of the robot using the ...

    • Direction Following Control of Planar Snake Robots Using Virtual Holonomic Constraints 

      Mohammadi, Alireza; Rezapour, Ehsan; Maggiore, Manfredi; Pettersen, Kristin Ytterstad (Journal article; Peer reviewed, 2015)
      This paper investigates the problem of direction following for planar snake robots. The control objective is to regulate the linear velocity vector of the snake robot to a constant reference while guaranteeing boundedness ...

      This paper investigates the problem of maneuvering control for planar snake robots. The control objective is to make the center of mass of the snake robot converge to a desired path and traverse the path with a desired ...

    • Model-based Locomotion Control of Underactuated Snake Robots 

      Rezapour, Ehsan (Doctoral thesis at NTNU;2015:46, Doctoral thesis, 2015)
      Snake robots are a class of biologically inspired robots which are built to emulate the features of biological snakes. These robots are underactuated, i.e. they have fewer control inputs than degrees of freedom, and ...

    • Path Following Control of a Planar Snake Robot with an Exponentially Stabilizing Joint Control Law
