Cardiac Muscle-cell Based Actuator and Self-stabilizing Biorobot - PART 1.

Journal of visualized experiments : JoVE
Biological machines often referred to as biorobots, are living cell- or tissue-based devices that are powered solely by the contractile activity of living components. Due to their inherent advantages, biorobots are gaining interest as alternatives to...

Morphological self stabilization of locomotion gaits: illustration on a few examples from bio-inspired locomotion.

Bioinspiration & biomimetics
To a large extent, robotics locomotion can be viewed as cyclic motions, named gaits. Due to the high complexity of the locomotion dynamics, to find the control laws that ensure an expected gait and its stability with respect to external perturbations...

Wet-Spun Biofiber for Torsional Artificial Muscles.

Soft robotics
The demands for new types of artificial muscles continue to grow and novel approaches are being enabled by the advent of new materials and novel fabrication strategies. Self-powered actuators have attracted significant attention due to their ability ...

Stiffness Customization and Patterning for Property Modulation of Silicone-Based Soft Pneumatic Actuators.

Soft robotics
Soft pneumatic actuators (SPAs), as novel types of motion drivers for robotic devices, excel in many applications, such as rehabilitation and biomimicry, which demand compliance and softness. To further expand their scope of utilization, the SPAs sho...

A miniaturized wall-climbing segment robot inspired by caterpillar locomotion.

Bioinspiration & biomimetics
Caterpillars are very successful soft-bodied climbers that navigate in complex environments. This paper develops a multi-segmented robot climbing on vertical surfaces using dry adhesive pads, inspired by caterpillar locomotion. The miniaturized robot...

Gait studies for a quadrupedal microrobot reveal contrasting running templates in two frequency regimes.

Bioinspiration & biomimetics
Performance metrics such as speed, cost of transport, and stability are the driving factors behind gait selection in legged locomotion. To help understand the effect of gait on the performance and dynamics of small-scale ambulation, we explore four q...

Template for the neural control of directed stepping generalized to all legs of MantisBot.

Bioinspiration & biomimetics
We previously developed a neural controller for one leg of our six-legged robot, MantisBot, that could direct locomotion toward a goal by modulating leg-local reflexes with simple descending commands from a head sensor. In this work, we successfully ...

Propulsive performance of an under-actuated robotic ribbon fin.

Bioinspiration & biomimetics
Many aquatic animals propelled by elongated undulatory fins can perform complex maneuvers and swim with high efficiency at low speeds. In this propulsion, one or multiple waves travel along an elastic fin composed of flexible rays. In this study, we ...

Design of hair-like appendages and comparative analysis on their coordination toward steady and efficient swimming.

Bioinspiration & biomimetics
The locomotion of water beetles has been widely studied in biology owing to their remarkable swimming skills. Inspired by the oar-like legs of water beetles, designing a robot that swims under the principle of drag-powered propulsion can lead to high...

Study on electric energy consumed in intermittent series-parallel elastic actuators (iSPEA).

Bioinspiration & biomimetics
On compliant actuators, intermittent series-parallel elastic actuators (iSPEA) can reduce motor load by variable load cancellation through recruitment of parallel springs by a single motor. However, the potential to reduce electric energy consumed, c...
