Geometry generation principle and meshing properties of a new gear drive
The generation principle of composite cycloid is proposed for the tooth profile of external drive. Firstly, a two-link mechanism is developed as the equivalent mechanism to describe the geometric principle of cycloid by introducing the motion ...

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping
This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...

Is There A Pure Electronic Ferroelectric?
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Study on the Design and Modification Method of the Cycloid Gear Tooth Profile
A new tooth profile curve equation of the cycloid gear is proposed based on the gear meshing transmission principle. Due to the problem that complex cycloid equation is difficult to be substituted directly with the software for modeling, the method of ...

MODELING AND SIMULATION OF CYCLOID CURVES WITH APPLICATION IN ROBOTICS [PDF]
Mechanical power transmission by reducing the rotating speed under a constant transmission ratio represents the function of a large group of products known as speed reducers. Cycloid gearing roller (invented by L.

VIBRATION MODAL CHARACTERISTICS OF THE HIGH-PRECISION RV REDUCER CONSIDERING MESH STATE
The transmission characteristics of the precision RV reducer is mainly determined by the mesh state between the cycloid gear and pin shell parts,and vibration modal characteristics of the cycloid gear have important effects on the dynamic characteristics

Revisiting the Conservation Status of Cobitis taenia in Switzerland Using Environmental DNA
ABSTRACT Freshwater loaches of the genus Cobitis are small benthic fish inhabiting fine sediments in slow‐flowing rivers and vegetated lakes. Due to their small size, low economic value and inconspicuous behaviour, they are rarely studied, and their taxonomy and distribution remain poorly understood.
