Experimental study of passive creeping for a snake-like robot

, 2011
The control of a snake-like robot is a challenging problem because of unknown environments and complex dynamics. We have proposed an energy-based method, called passive creeping, to control the serpentine locomotion. In the paper, we present a hypothesis

CPG-controlled asymmetric locomotion of a snake-like robot for obstacle avoidance

, 2009
To realize the obstacle avoidance of a snake-like robot in unstructured environment, an asymmetric locomotion of snake-like robot is introduced. Imitating from the locomotion of natural snakes, the turn motion and the round motion of the snake-like robot

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

Simulation study on serpentine locomotion of underwater snake-like robot

, 2015
Serpentine locomotion of underwater snake-like robot is very complicated. In order to better control the motion state, a simulation model of underwater snake-like robot is established to investigate the relationship between the motion performance and the
