Slithering towards autonomy: a self-contained soft robotic snake platform with integrated curvature sensing.

Bioinspiration & biomimetics
Soft robotic snakes promise significant advantages in achieving traveling curvature waves with a reduced number of active segments as well as allowing for safe and adaptive interaction with the environment and human users. However, current soft robot...

Planar maneuvering control of underwater snake robots using virtual holonomic constraints.

Bioinspiration & biomimetics
This paper investigates the problem of planar maneuvering control for bio-inspired underwater snake robots that are exposed to unknown ocean currents. The control objective is to make a neutrally buoyant snake robot which is subject to hydrodynamic f...

Towards autonomous locomotion: CPG-based control of smooth 3D slithering gait transition of a snake-like robot.

Bioinspiration & biomimetics
Snake-like robots with 3D locomotion ability have significant advantages of adaptive travelling in diverse complex terrain over traditional legged or wheeled mobile robots. Despite numerous developed gaits, these snake-like robots suffer from unsmoot...

Non-iterative geometric approach for inverse kinematics of redundant lead-module in a radiosurgical snake-like robot.

Biomedical engineering online
BACKGROUND: Snake-like robot is an emerging form of serial-link manipulator with the morphologic design of biological snakes. The redundant robot can be used to assist medical experts in accessing internal organs with minimal or no invasion. Several ...

Tegotae-based decentralised control scheme for autonomous gait transition of snake-like robots.

Bioinspiration & biomimetics
Snakes change their locomotion patterns in response to the environment. This ability is a motivation for developing snake-like robots with highly adaptive functionality. In this study, a decentralised control scheme of snake-like robots that exhibite...

Soft Rod-Climbing Robot Inspired by Winding Locomotion of Snake.

Soft robotics
Soft climbing robots have attracted much attention of researchers for their potential applications on the wall or inside the tube. However, making a soft robot climb on the outer surface of a rod or tube by agile and efficient motion has long been a ...

Decoding Decentralized Control Mechanism Underlying Adaptive and Versatile Locomotion of Snakes.

Integrative and comparative biology
Snakes have no limbs and can move in various environments using a simple elongated limbless body structure obtained through a long-term evolutionary process. Specifically, snakes have various locomotion patterns, which they change in response to cond...

Lateral Oscillation and Body Compliance Help Snakes and Snake Robots Stably Traverse Large, Smooth Obstacles.

Integrative and comparative biology
Snakes can move through almost any terrain. Similarly, snake robots hold the promise as a versatile platform to traverse complex environments such as earthquake rubble. Unlike snake locomotion on flat surfaces which is inherently stable, when snakes ...
