Abstract: This paper proposes a novel deployable hexahedron mobile mechanism that is rigidly linked by only prismatic joints. The mechanism that is a completely symmetrical structure can always keep the walking capability when any ...

Abstract: An untraditional application of the four-link RCCR (two revolute and two cylindric joints) mechanism is presented in this paper and is used as a novel biped walking mechanism. By taking advantage ...

Abstract: In this paper, a rolling mechanism constructed by a spatial 8bar linkage is proposed. The eight links are connected with eight revolute joints, forming a single closedloop with two degrees of freedom (DOF). By kinematic ...

Abstract: This paper presents a novel underactuated tetrahedral mobile robot with 12 degrees-of-freedom (DOFs). The robot contains four vertices and six URU chains (where U represents a universal joint and R represents an actuated ...

Abstract: A novel application of the well-known single degree-of-freedom (DOF) Bricard mechanism is proposed in this paper. By optimizing the links’ shape and installing motors reasonably, we put forward a ground mobile Bricard ...

Abstract: Inspired by lizards, a novel mobile platform with revolving linkage legs is proposed. The platform consists of four six-bar bipedal modules, and it is designed for heavy transportation on unstructured terrain. The platform ...

Abstract: This article presents a comprehensive performance analysis of the step-climbing and passive rolling modes of a hexagon rolling mechanism with single-degree-of-freedom, based on its structural characteristics and the ...

Abstract: Abstract. In response to the demand for rapid and stable docking and separation of unmanned ground vehicles during specific tasks, a single-drive chuck-type docking mechanism based on the Archimedean spiral is proposed. ...

Abstract: Abstract. Achieving stable and coordinated locomotion in high-dimensional humanoid robots remains challenging, particularly considering variations in support phases, model uncertainties, and redundancy arising from ...

Abstract: We put forward a novel proposition that a mechanism can move in a constant direction and change its moving directions only by one actuator and construct a singleDOF (degree of freedom) ground mobile mechanism based on the ...
