Motion–Force Interaction Performance of Parallel Robotic Mechanisms

SmartBot, Volume 1, Issue 1, March 2025.
This review addresses a critical research gap by summarizing significant studies on the motion–force interaction performance of parallel robotic mechanisms, also known as motion/force transmission and constraint performance. It explores the interaction mechanism where transmission wrenches perform work on allowable motion for transmission, while ...

Towards a global understanding of tree mortality

New Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

A Systematic Review of Sensor Vulnerabilities and Cyber‐Physical Threats in Industrial Robotic Systems

IET Cyber-Physical Systems: Theory &Applications, Volume 10, Issue 1, January/December 2025.
This paper addresses a critical gap in the literature of industrial robotics cybersecurity by presenting a comprehensive analysis of vulnerabilities in the sensing systems of industrial robots. In particular, we systematically explore how sensor performance limits, faults and biases can be exploited by attackers who can then turn these inherent ...

Insight Into the Significance of Trajectory Tracking Control of a 3R Robot Manipulator in the Presence of External Disturbances

Journal of Mathematics, Volume 2025, Issue 1, 2025.
Robotics systems deal with uncertainties and nonlinearities of robot manipulator dynamics, such as the mass of the payload, which is an unmodeled dynamic uncertainty, and external disturbances caused by fluctuations from external sources. Hence, it has huge industrial applications.
