Edible Pouch Motors

Advanced Robotics Research, EarlyView.
Edible robotics is an emerging field that leverages edible materials to construct robotic systems. This study presents a method to create thin, lightweight, yet powerful edible soft actuators, namely edible pouch motors. The successful operation of these edible actuators and grippers renders their potential to advance future developments in edible ...

Effects of inclination angle and confining pressure on triaxial unloading-induced slip behaviors of shale fractures

Frontiers in Earth Science
To explore the effects of fracture inclination angle θ and confining pressure σ3t on the slip behaviors and friction properties of fractures, the triaxial unloading-induced slip experiments were performed on the shale fractures. The results show that the

Stick-slip vs. smooth sliding in the multicontact interface

, 2015
The stick-slip and smooth sliding regimes of motion for the multicontact frictional interface are studied within the earthquake-like model. It is shown that the stick-slip appears when two necessary conditions are fulfilled: first, the system must be ...

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

Advanced 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.
