An important energy expense in the legged locomotion of both animals and robots is the mechanical antagonism between muscles/actuators, which is the positive mechanical work of some muscles opposed by the simultaneous negative work of the o...
Application of reduced sensor movement sequences as a precursor for search area partitioning and a selection of discrete EEV contour-ring fragments for active electrolocation [0.03%]

Five unique soft robotic jellyfish were manufactured with eight pneumatic network tentacle actuators extending radially from their centers. These jellyfish robots were able to freely swim untethered in the ocean, to steer from side to side,...

Soft actuators have played an indispensable role in generating compliant motions of soft robots. Among the various soft actuators explored for soft robotic applications, dielectric elastomer actuators (DEAs) have caught the eye with their i...

Stone corals do not use calcium carbonate in the form of calcite, which has a calculated energy gap of 3.93 eV, but in the form of aragonite, which has a calculated energy gap of 2.88 eV (here experimentally determined to amount to 2.46 eV)...

During typical human walking, the metatarsophalangeal joints undergo extension/flexion, which we term toe joint articulation. This toe joint articulation impacts locomotor performance, as evidenced by prior studies on prostheses, footwear, ...

General understanding of adhesion failure of setal attachment pads at some particular substrate roughness is important for construction of biologically active adhesive and anti-adhesive surfaces. Here we present a numerical model which is c...

This study investigated a novel polarisation detection model based on the microstructure of rhabdom in mantis shrimp eyes, in which a single unit can detect two directions of orthogonal polarisation. The bionic model incorporated multi-laye...
