The entire frog model consists of the body, thigh, crus, and palm connected by the hip, knee, and ankle joints, respectively.
de Luna, Hödl, and Amézquita (2010) showed in a follow-up study that movement not only of the inflated vocal sac but also of a robotic frog model provoked territorial aggression in males of A. femoralis.
Robotic amphibians have also graced the ethological stage, with the introduction of electromechanical dart-poison frog models by Narins et al. to study aggression and cross-modal integration.
To assess the gene expression profiles in the frog model, we designed a novel multispecies frog cDNA microarray.
In this sense, our 1993 model of frog egg extracts is actually more appropriate as a model of mammalian cells than of frog eggs, for which it was intended.
Or we might say it is a model of frog eggs with constitutively phosphorylated Gwl.
"The frog is really a fabulous model of hearing," says Narins.
For their part, Raper and his colleagues are intrigued by Morris's experiments; they're interested in repeating some of her frog work in their animal model of choice, zebrafish.
How realistic does a male túngara frog robot need to be? Females apparently respond to the inflating artificial vocal sac as the call is being played no differently than they do when the model of the frog's body accompanies these stimuli.
Using experimental observations, Pandey et al. established a CAD model of a bionic frog swimming robot to mimic biological frog motions [15].
Figure 1 shows the model of the frog-inspired robot, which is based on the morphology of real frogs.
