Abstract: A rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit and a hybrid robot platform thereof is provided and includes a vertical rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit and a horizontal rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit, which both include a moving device, a moving drive, a steering frame, a lifting frame, a spring device and a driving differential wheel set, in combination with a frame, a driver set, a battery pack and a control box, forming a multi-degree-of-freedom parallel mechanism platform. The hybrid robot platform including the rigid-flexible coupling multi-degree-of-freedom walking position-adjusting leg unit as provided by the present disclosure has functions of a rigid position adjustment, an elastic suspension and a rigid-flexible coupling position adjustment, and can automatically adapt to a working condition of the uneven ground.

Abstract: Provided is a compound having Formula I where rings A and B are independently a five-membered or six-membered, carbocyclic or heterocyclic ring, each of which is optionally aromatic; together with nitrogen atoms bonded to ring A and ring B, ring W is a 5-membered N-heterocyclic carbene; and the remaining variables are as defined herein.

Abstract: An active-passive differential series-parallel connection supporting leg, a gravity-based closing series-parallel connection supporting leg, and a six-degree-of-freedom position-adjusting robot platform are provided. The six-degree-of-freedom position-adjusting robot platform is formed of a plurality of legs distributed in parallel, and includes a frame, a distributed controller, and multi-chain parallel legs, wherein a plurality of legs are fixedly connected with the frame through a base. The present disclosure integrates an omnidirectional movement and position adjustment to solve problems that the existing position-adjusting platform is fixed or moved inflexibly, the structure is over complicated, the occupation space is excessive, and the movement error is large, and thereby effectively expanding application range of the six-degree-of-freedom position-adjusting robot platform.

Abstract: A compound selected from the group consisting of Formula I, Formula II, and Formula III, wherein ring A, ring B, and ring C are independently a five-membered or six-membered, carbocyclic or heterocyclic ring, each of which is optionally aromatic; ring W of Formula I is a 6-membered heterocyclic ring, and ring W of Formula II or Formula III is a 5-membered or 6-membered heterocyclic ring; L is a monodentate ligand with a metal coordinating member selected from the group consisting of C, N, O, S, and P; and M is a metal selected from the group consisting of Cu, Au, and Ag.
