Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Kinematic Ages of the Tucana–Horologium, Columba, and Carina Associations

The Astrophysical Journal
The traceback method allows the computation of the kinematic age of nearby young associations from astrometric and kinematic data alone, circumventing the need for stellar evolution models.

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 ...

Stellar kinematics in 30 Doradus

, 2001
Con espectroscopía multiranura de 180 estrellas en el cumulo ionizante de 30 Doradus, hemos obtenido velocidades radiales confiables para 58 estrellas. Con ellas, calculamos la dispersión de velocidades, la cual es de 35 km s-1. Si el cúmulo está relajado dinámicamente, la masa virial estimada es de ~ 1 x 107 M.

Inferring intrahalo light from stellar kinematics

Astronomy & Astrophysics
Context. In the context of structure formation, disentangling the central galaxy stellar population from the stellar intrahalo light can help us shed light on the formation history of the halo as a whole, as the properties of the stellar components are expected to retain traces of the formation history.
