A Thickness-Invariant Origami Robot With Integrated Actuation and Multimodal Locomotion. [PDF]

open access: yesAdv Sci (Weinh)
A thickness‐invariant variation on the Yoshimura origami pattern is used as the basis of a robot, allowing power, actuation, and control systems to be embedded within the thickened panels of the pattern. The robot uses multiple kinematic branches to achieve distinct modes of locomotion, such as walking, running, galloping, and turning. ABSTRACT Origami

Kinematic Graph for Motion Planning of Robotic Manipulators

open access: yes, 2022
We introduce a kinematic graph in this article. A kinematic graph results from structuring the data obtained from the sampling method for sampling-based motion planning algorithms in robotics with the motivation to adapt the method to the positioning ...

Kinematic coupling between the foot and lower limb during gait [PDF]

open access: yes, 2006
INTRODUCTION: Abnormal kinematic coupling between the foot and lower limb has been associated with chronic overuse injuries of the lower extremity during running. However, the normal coupling relationship between the two segments remains unclear. The

The Influence of Specimen Misalignment on Wear in Conforming Pin on Disk Tests [PDF]

open access: yes, 2004
A pin-on-disk test apparatus was modified to decrease the degree of misalignment between the pin end and the disk counterface. This was achieved by separate alignment of both pin and disk.

Ideal Graph of a Graph [PDF]

open access: yes, 2011
In this paper, we introduce ideal graph of a graph and study some of its properties. We characterize connectedness, isomorphism of graphs and coloring property of a graph using ideal graph.

Towards a Maude tool for model checking temporal graph properties [PDF]

open access: yes, 2011
We present our prototypical tool for the verification of graph transformation systems. The major novelty of our tool is that it provides a model checker for temporal graph properties based on counterpart semantics for quantified m-calculi.

Inverse kinematic analysis for triple-octahedron variable-geometry truss manipulators [PDF]

open access: yes, 2001
In this paper, a new triple-octahedron variable-geometry truss manipulator is presented. Its inverse kinematic solutions in closed form are studied. An input-output displacement equation in one output variable is derived.

Assessing Graph Robustness through Modified Zagreb Index

open access: yes, 2022
Graph robustness or network robustness is the ability that a graph or a network preserves its connectivity or other properties after the loss of vertices and edges, which has been a central problem in the research of complex networks.
