Aerial-aquatic robots capable of crossing the air-water boundary and hitchhiking on surfaces.

Science robotics
Many real-world applications for robots-such as long-term aerial and underwater observation, cross-medium operations, and marine life surveys-require robots with the ability to move between the air-water boundary. Here, we describe an aerial-aquatic ...

Force scaling and efficiency of elongated median fin propulsion.

Bioinspiration & biomimetics
Several fishes swim by undulating a thin and elongated median fin while the body is mostly kept straight, allowing them to perform forward and directional maneuvers. We used a robotic vessel with similar fin propulsion to determine the thrust scaling...

LM-Jelly: Liquid Metal Enabled Biomimetic Robotic Jellyfish.

Soft robotics
Jellyfish have attracted worldwide attention owing to their fantastic moving styles, which also inspired development in soft robotics to meet the demands of underwater surveillance. In this study, a soft robotic jellyfish integrated liquid metal coil...

Toward a Multifunctional Light-Driven Biomimetic Mudskipper-Like Robot for Various Application Scenarios.

ACS applied materials & interfaces
The systematicness, flexibility, and complexity of natural biological organisms are a constant stream of inspiration for researchers. Therefore, mimicking the natural intelligence system to develop microrobotics has attracted broad interests. However...

Functionalized Spiral-Rolling Millirobot for Upstream Swimming in Blood Vessel.

Advanced science (Weinheim, Baden-Wurttemberg, Germany)
Untethered small robots with multiple functions show considerable potential as next-generation catheter-free systems for biomedical applications. However, owing to dynamic blood flow, even effective upstream swimming in blood vessels remains a challe...

Decoupling and Reprogramming the Wiggling Motion of Midge Larvae Using a Soft Robotic Platform.

Advanced materials (Deerfield Beach, Fla.)
The efficient motility of invertebrates helps them survive under evolutionary pressures. Reconstructing the locomotion of invertebrates and decoupling the influence of individual basic motion are crucial for understanding their underlying mechanisms,...

Force Optimization of Elongated Undulating Fin Robot Using Improved PSO-Based CPG.

Computational intelligence and neuroscience
Biorobotic fishes have a huge impact on the development of underwater devices due to both fast swimming speed and great maneuverability. In this paper, an enhanced CPG model is investigated for locomotion control of an elongated undulating fin robot ...

A fluid-driven soft robotic fish inspired by fish muscle architecture.

Bioinspiration & biomimetics
Artificial fish-like robots developed to date often focus on the external morphology of fish and have rarely addressed the contribution of the structure and morphology of biological muscle. However, biological studies have proven that fish utilize th...

Data-driven geometric system identification for shape-underactuated dissipative systems.

Bioinspiration & biomimetics
Modeling system dynamics becomes challenging when the properties of individual system components cannot be directly measured, and often requires identification of properties from observed motion. In this paper, we show that systems whose movement is ...

Tunable stiffness in fish robotics: mechanisms and advantages.

Bioinspiration & biomimetics
One of the emerging themes of fish-inspired robotics is flexibility. Adding flexibility to the body, joints, or fins of fish-inspired robots can significantly improve thrust and/or efficiency during locomotion. However, the optimal stiffness depends ...
