A study on tolerance design of machine tool components based on shape generation motions

open access: yesNihon Kikai Gakkai ronbunshu, 2016
The kinematic motion deviations of the five-axis machining centers are deeply influenced by the geometric deviations of the components, such as guide-ways and bearings.

Common kinematic synergies of various human locomotor behaviours

open access: yesRoyal Society Open Science, 2021
Humans show a variety of locomotor behaviours in daily living, varying in locomotor modes and interaction styles with the external environment. However, how this excellent motor ability is formed, whether there are some invariants underlying various ...

TapMo: Shape-aware Motion Generation of Skeleton-free Characters

open access: yesCoRR, 2023
Previous motion generation methods are limited to the pre-rigged 3D human model, hindering their applications in the animation of various non-rigged characters. In this work, we present TapMo, a Text-driven Animation Pipeline for synthesizing Motion in a broad spectrum of skeleton-free 3D characters.

Mathematical Properties of Generalized Shape Expansion-Based Motion Planning Algorithms

open access: yesCoRR, 2021
Motion planning is an essential aspect of autonomous systems and robotics and is an active area of research. A recently-proposed sampling-based motion planning algorithm, termed 'Generalized Shape Expansion' (GSE), has been shown to possess significant improvement in computational time over several existing well-established algorithms. The GSE has also

Co-generation of Collision-Free Shapes for Arbitrary One-Parametric Motion

open access: yesComputer-Aided Design, 2022
Mechanical assemblies can exhibit complex relative motions, during which collisions between moving parts and their surroundings must be avoided. To define feasible design spaces for each part's shape, "maximal" collision-free pointsets can be computed using configuration space modeling techniques such as Minkowski operations and sweep/unsweep.
