Squat motion of a bipedal robot using real‐time kinematic prediction and whole‐body control

IET Cyber-Systems and Robotics, Volume 4, Issue 4, Page 298-312, December 2022., 2022
Abstract Squatting is a basic movement of bipedal robots, which is essential in robotic actions like jumping or picking up objects. Due to the intrinsic complex dynamics of bipedal robots, perfect squatting motion requires high‐performance motion planning and control algorithms.

Paleomagnetic Constraints From 925 Ma Mafic Dykes in North China and Brazil: Implications for the Paleogeography of Rodinia

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 9, September 2022., 2022
Abstract Coeval Neoproterozoic mafic dykes with a well‐constrained isotopic age of 925 Ma are distributed in the North China Craton (NCC) of China and São Francisco Craton (SFC) of Brazil. Several recent studies favor the hypothesis that these two cratons were connected during 925 Ma and constituted building cratons for the supercontinent Rodinia ...

The plasma membrane H+‐ATPase FgPMA1 regulates the development, pathogenicity, and phenamacril sensitivity of Fusarium graminearum by interacting with FgMyo‐5 and FgBmh2

Molecular Plant Pathology, Volume 23, Issue 4, Page 489-502, April 2022., 2022
FgPMA1, FgBmh2, and FgMyo‐5 form a complex to regulate the development, pathogenicity, and phenamacril sensitivity of Fusarium graminearum. Abstract Fusarium graminearum, as the causal agent of Fusarium head blight (FHB), not only causes yield loss, but also contaminates the quality of wheat by producing mycotoxins, such as deoxynivalenol (DON).

Statistical determination of rainfall-runoff erosivity indices for single storms in the Chinese Loess Plateau. [PDF]

PLoS ONE, 2015
Correlation analysis is popular in erosion- or earth-related studies, however, few studies compare correlations on a basis of statistical testing, which should be conducted to determine the statistical significance of the observed sample difference. This

Fuzzy model‐based multi‐objective dynamic programming with modified particle swarm optimization approach for the balance control of bicycle robot

IET Control Theory &Applications, Volume 16, Issue 1, Page 7-19, January 2022., 2022
Abstract Existing studies for the balance control of unmanned bicycle robots only consider constant forward velocity and a single optimal objective that cannot be applied to the complex motion situation. To balance the bicycle robot with time‐varying forward velocity, only with the steering actuator, the multiple objective optimal balance control issue

Accurate Terrain Estimation for Humanoid Robot Based on Disturbance State Observer

IEEE Access, 2021
This study proposes a novel reactive terrain estimation system for humanoid robots from the perspective of a state observer. The design process is as follows: the underfoot force disturbance is converted into an underfoot position disturbance by using an
