Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains

Advanced Robotics Research, EarlyView.
How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

The MAGPI survey: using kinematic asymmetries in stars and gas to dissect drivers of galaxy dynamical evolution

Monthly Notices of the Royal Astronomical Society
ABSTRACT We present a study of kinematic asymmetries from the integral field spectroscopic surveys MAGPI and SAMI. By comparing the asymmetries in the ionized gas and stars, we aim to disentangle the physical processes that contribute to kinematic disturbances.

RR Lyrae stars and the distant Galactic halo - Distribution, chemical composition, kinematics, and dynamics

The Astrophysical Journal, 1985
Published observational data on 29 outer-Galactic-halo RR Lyr stars (Saha, 1984, and Saha and Oke, 1984) and from other surveys are analyzed to characterize the mass distribution, chemical composition, kinematics, and dynamics of the outer Galaxy (up to galactocentric radius R = 40 kpc).

The Rotation of the Halo of NGC 6822 Determined From the Radial Velocities of Carbon Stars [PDF]

, 2016
The kinematics of stars in galaxies is becoming a key means to understand the dynamics of galaxies, their formation and merger history. For many years, kinematics has been measured using integrated field techniques in the optical, infra-red and radio ...

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.
