Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Cooperative Photocatalysis of 9,10‐Phenanthrenequinone and Sn(OTf)2 for Direct Mannich Reaction of Ethers via Hydrogen Atom Transfer Pathway

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A

Thioether Synthesis via the Nickel‐Catalyzed Electrochemical Cross Electrophile Coupling of Aryl/Alkyl Disulfides and Aryl/Alkyl Halides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A nickel catalyzed electrochemical cross‐electrophile coupling approach for the base‐free synthesis of (un)symmetric (hetero)aryl and alkyl sulfides from organic halides and disulfides is described. The reaction is broadly applicable and tolerates water and air atmosphere. A formal cross‐electrophile coupling approach enables the base‐free synthesis of
