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: 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 ...

Abstract: Monotone paths are useful in many engineering design applications. In this paper, we address the problem of answering monotone descent path queries on terrains that are continually changing. A terrain can be represented ...

Abstract: Precise porosity control is highly desirable for improving the electrochemical performance of solid oxide fuel cells (SOFCs). Freeze casting is an established method for enabling high bulk porosity in structures and ...
