The Colour Changes In Lizards, Particularly In Phrynosoma [PDF]

open access: yes, 1938
The activities of the melanophore system of Phrynosoma in comparison with that of Chamaeleo may be stated categorically in the following way. I. The blanching of Phrynosoma blainvillii is due (1) to the action of its concentrating nerve-fibres on ...

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

open access: yesAdvanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators

open access: yesAdvanced Robotics Research, EarlyView.
Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.
