Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

A Snake-like Robot for Inspection Tasks

, 2008
In the earth, there are many kinds of snake. The movement of a real snake is very flexible as it can be adapted to various environments. Snakes are able to move on rough surfaces, they cross obstacles, and they can creep into areas that are very ...

Head-navigated locomotion of a snake-like robot for its autonomous obstacle avoidance

, 2010
Inspired from the natural motion of snakes, a head-navigated locomotion is proposed for snake-like robots in this paper. Different from the traditional serpentine motion, the head of the snake-like robot would always maintain its direction along the ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Twist-related locomotion of a snake-like robot

, 2006
As a hyper-redundant robot, a 3D snake-like robot can perform many other configurations and types of locomotion adapted to environment except for mimicking the natural snake locomotion. The natural snake locomotion usually limits locomotion capability of

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail

Small, EarlyView.
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.

Sensor-driven neural controller for self-adaptive collision-free behavior of a snake-like robot

, 2011
Biologically inspired control approaches based on the central pattern generator (CPG) have been studied to apply to a snake-like robot. One of the important problems is to determine how to construct a sensor-driven neural system in order to control the ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

Wildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.
