Contact feedback helps snake robots propel against uneven terrain using vertical bending.

Bioinspiration & biomimetics
Snakes can bend their elongate bodies in various forms to traverse various environments. We understand well how snakes use lateral body bending to push against asperities on flat ground for propulsion, and snake robots can do so effectively. However,...

Bioinspired Soft Spine Enables Small-Scale Robotic Rat to Conquer Challenging Environments.

Soft robotics
For decades, it has been difficult for small-scale legged robots to conquer challenging environments. To solve this problem, we propose the introduction of a bioinspired soft spine into a small-scale legged robot. By capturing the motion mechanism of...

Patent Review of Lower Limb Rehabilitation Robotic Systems by Sensors and Actuation Systems Used.

Sensors (Basel, Switzerland)
Robotic systems for lower limb rehabilitation are essential for improving patients' physical conditions in lower limb rehabilitation and assisting patients with various locomotor dysfunctions. These robotic systems mainly integrate sensors, actuation...

Learning to cooperate for low-Reynolds-number swimming: a model problem for gait coordination.

Scientific reports
Biological microswimmers can coordinate their motions to exploit their fluid environment-and each other-to achieve global advantages in their locomotory performance. These cooperative locomotion require delicate adjustments of both individual swimmin...

Biodegradable Magnetic Hydrogel Robot with Multimodal Locomotion for Targeted Cargo Delivery.

ACS applied materials & interfaces
Recent strides in the development of untethered miniature robots have shown the advantages of diverse actuation methods, flexible maneuverability, and precise locomotion control, which has made miniature robots attractive for biomedical applications ...

In situ sensing physiological properties of biological tissues using wireless miniature soft robots.

Science advances
Implanted electronic sensors, compared with conventional medical imaging, allow monitoring of advanced physiological properties of soft biological tissues continuously, such as adhesion, pH, viscoelasticity, and biomarkers for disease diagnosis. Howe...

The neuromechanics of animal locomotion: From biology to robotics and back.

Science robotics
Robotics and neuroscience are sister disciplines that both aim to understand how agile, efficient, and robust locomotion can be achieved in autonomous agents. Robotics has already benefitted from neuromechanical principles discovered by investigating...

Pacific lamprey inspired climbing.

Bioinspiration & biomimetics
Snakes and their bio-inspired robot counterparts have demonstrated locomotion on a wide range of terrains. However, dynamic vertical climbing is one locomotion strategy that has received little attention in the existing snake robotics literature. We ...

Hierarchical Vision Navigation System for Quadruped Robots with Foothold Adaptation Learning.

Sensors (Basel, Switzerland)
Legged robots can travel through complex scenes via dynamic foothold adaptation. However, it remains a challenging task to efficiently utilize the dynamics of robots in cluttered environments and to achieve efficient navigation. We present a novel hi...

A worm-inspired robot based on origami structures driven by the magnetic field.

Bioinspiration & biomimetics
With the rapid development of origami technology, worm-inspired origami robots have attracted tremendous interest owing to their colourful locomotion behaviours, such as creeping, rolling, climbing and obstacle crossing. In the present study, we aim ...
