Arti4D: Statistical Analysis and Modelling of the Spatio‐temporal Variability in Articulated 4D Shapes

Computer Graphics Forum, EarlyView.
Abstract We propose a novel framework for the statistical modeling and analysis of the spatio‐temporal shape variability in articulated 4D (i.e., 3D + time) shapes such as human bodies and animals. We treat articulated 3D shapes, represented using parametric models such as SMPL or its variants, as elements of the product space of shape and pose ...

Quadruped Robot with Stabilization Algorithm on Uneven Floor using 6 DOF IMU based Inverse Kinematic [PDF]

Robotics technology is always growing very quickly. One type of the robot is 4 legged robot (Quadruped). The Problem from this robot is if quadruped find the uneven floor, the movement of robot can be late and the center of the gravity are not balance ...

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

Journal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

Learning Human-Robot Handshaking Preferences for Quadruped Robots

Quadruped robots are showing impressive abilities to navigate the real world. If they are to become more integrated into society, social trust in interactions with humans will become increasingly important.

OPTIMAL TURNING GAIT OF A QUADRUPED WALKING ROBOT

, 1995
The analysis of the gait mode is an important step for constructing a walking robot. In this study an optimal turning gait of a four-legged walking robot is proposed, which maximizes walking speed keeping walking stability larger than a certain required ...
