Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Using Moment of Inertia and Observable Planetary Features to Approximate the Two-Layer Structure of Earth, Jupiter, and Neptune

open access: yesUndergraduate Journal of Mathematical Modeling: One + Two, 2019
This paper examines the interior structure and composition of Earth, Jupiter, and Neptune by using moment of inertia (MoI) and observable planetary features to create approximate two-layer interior structure models. The moment inertia of a uniform sphere,

Interior and Gravity Field Models for Uranus Suggest a Mixed-composition Interior: Implications for the Uranus Orbiter and Probe

open access: yesThe Planetary Science Journal
The interior composition and structure of Uranus are ambiguous. It is unclear whether Uranus is composed of fully differentiated layers dominated by an icy mantle or has smooth compositional gradients.

Planetary magnetism: Unlocking the secrets of planetary interiors [PDF]

open access: yesAIP Conference Proceedings, 2015
Many planetary bodies in our solar system have magnetic fields that we can observe with spacecraft instruments. These magnetic fields are generated deep in planetary interiors by complex motions in liquid conductors. Because these magnetic fields are observable outside of the planet, they can act as important probes of planetary interiors. In this talk

Reassessing Sub-Neptune Structure, Radii, and Thermal Evolution

open access: yesThe Astrophysical Journal
We present a novel python-based 1D sub-Neptune evolution model that emphasizes the thermal evolution and potential solidification of the rock/iron core and the structure of the radiative atmosphere. This model explores planetary structure from the molten
