Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...
