Electrically Activated Soft Robots: Speed Up by Rolling.

Soft robotics Nov 11, 2020
Soft robots show excellent body compliance, adaptability, and mobility when coping with unstructured environments and human-robot interactions. However, the moving speed for soft locomotion robots is far from that of their rigid partners. Rolling loc...

Spiking neural state machine for gait frequency entrainment in a flexible modular robot.

PloS one Oct 21, 2020
We propose a modular architecture for neuromorphic closed-loop control based on bistable relaxation oscillator modules consisting of three spiking neurons each. Like its biological prototypes, this basic component is robust to parameter variation but...

Light-steered locomotion of muscle-like hydrogel by self-coordinated shape change and friction modulation.

Nature communications Oct 14, 2020
Many creatures have the ability to traverse challenging environments by using their active muscles with anisotropic structures as the motors in a highly coordinated fashion. However, most artificial robots require multiple independently activated act...

Randomness in appendage coordination facilitates strenuous ground self-righting.

Bioinspiration & biomimetics Oct 9, 2020
Randomness is common in biological and artificial systems, resulting either from stochasticity of the environment or noise in organisms or devices themselves. In locomotor control, randomness is typically considered a nuisance. For example, during dy...

Rapid two-anchor crawling from a milliscale prismatic-push-pull (3P) robot.

Bioinspiration & biomimetics Sep 11, 2020
Many crawling organisms such as caterpillars and worms use a method of movement in which two or more anchor points alternately push and pull the body forward at a constant frequency. In this paper we present a milliscale push-pull robot which is capa...

Realization of a push-me-pull-you swimmer at low Reynolds numbers.

Bioinspiration & biomimetics Sep 11, 2020
Locomotion at low Reynolds numbers encounters stringent physical constraints due to the dominance of viscous over inertial forces. A variety of swimming microorganisms have demonstrated diverse strategies to generate self-propulsion in the absence of...

Insect-inspired jumping robots: challenges and solutions to jump stability.

Current opinion in insect science Sep 10, 2020
Some insects can jump to heights that are several times their body length. At smaller scales, jumping mechanisms are constrained by issues relating to scaling of power generation, which insects have resolved over the course of their evolution. These ...
