Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

open access: yesAdvanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

Soft Robots Proprioception Through Stretchable Laser‐Induced Graphene Strain Sensors

open access: yesAdvanced Intelligent Systems, EarlyView.
This study demonstrates the potential of laser‐induced graphene and silicone sensors for soft pneumatic grippers’ proprioception. The sensors are thin, stretchable, mechanically transparent, and easy to integrate. Finite‐element method analysis identifies the finger's neutral bending plane and four sensor positions are tested to validate the ...

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching

open access: yesAdvanced Intelligent Systems, EarlyView.
Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...

Moduli Structures, Separability of the Kinematic Hilbert Space and Frames in Loop Quantum Gravity

open access: yes, 2016
We reassess the problem of separability of the kinematic Hilbert space in loop quantum gravity under a new mathematical point of view. We use the formalism of frames, a tool used in signal analysis, in order to remove the redundancy of the moduli structures in high valence graphs, without resorting to set extension of diffeomorphism group. For this, we
