Flexible Sensors for Robotics Tactile Perception: A Review

open access: yesAdvanced Robotics Research, EarlyView.
Flexible tactile sensing for robotics is reviewed through four interconnected dimensions. Physical mechanisms include piezoresistive, capacitive, piezoelectric, triboelectric, iontronic, and optical sensing. Structural design includes bioinspired, defect‐based, and MEMS‐based tactile systems.

WorMa: An Undulatory Robot With Center of Mass Regulation via Internal Fluid Redistribution for Amphibious Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

North Pacific meltwater weakens the Atlantic Meridional Overturning Circulation and preconditions Heinrich Stadial 1

open access: yesNature Communications
Heinrich Stadials provide insights into a potential future weakening of the Atlantic Meridional Overturning Circulation (AMOC), yet the mechanisms driving AMOC weakening during these intervals remain elusive.

Experimental cosmochemistry in the space station : report of workshops September 12-13, 1985 and February 24-25, 1986. [PDF]

open access: yes, 1986
The scientific discussions focused on two general areas of research: chemical and physical processes in the earliest history of the general areas of research, and general principles of magmatic process applicable both to planetary formation and evolution,

Toward Mechanical Intelligence in Robotics

open access: yesAdvanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

The self‐secondary crater population of the Hokusai crater on Mercury

open access: yesGeophysical Research Letters, 2016
Whether or not self‐secondaries dominate small crater populations on continuous ejecta deposits and floors of fresh impact craters has long been a controversy. This issue potentially affects the age determination technique using crater statistics.

Origami‐Inspired Morphing Fuselage for Agile Fixed‐Wing Flight

open access: yesAdvanced Robotics Research, EarlyView.
Conventional aircraft steer with rigid control surfaces. SoAR instead replaces the fuselage itself with a cable‐driven origami continuum body that bends in 3D and compresses on demand. Whole‐fuselage morphing steers fixed‐wing flight: achieving sharp, near‐zero‐radius turns and rapid braking without ailerons, rudder, or elevator, while the same ...

Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism

open access: yesAdvanced Robotics Research, EarlyView.
Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and
