Planning optimal minimum-jerk trajectories for redundant robots

In this paper, a minimum-jerk trajectory planning approach for redundant manipulators is presented. The proposed approach leverages not only the optimization of the time intervals between each of the way points of the assigned path, but also the optimal positions of a selected robot joint to reduce the jerk of the robot end-effector. This multi-stage optimization strategy is validated through extensive numerical simulations and experimental tests on a robot with seven degrees of freedom perfo...

PRIVACY CONCERNS IN INTERNATIONAL DATA TRANSFER AND LLM

In this contribution we address the privacy concerns posed by the transfer of personal data in the use of Large Language Models (LLMs). In the first section we highlight the weaknesses of the current legal framework, provided by the “EU-US Data Privacy Framework”, with a brief analysis of the ECJ rulings “Schrems I” and Schrems II”, which affected both the legal framework established by the “Safe Harbour Privacy Principles” and the “Privacy Shield”. In the second section we offer a comparativ...

A multi-scale spatial–temporal interaction fusion network for digital twin-based thermal error compensation in precision machine tools

The machining accuracy of precision machine tools (PMTs) directly determines the quality of high-accuracy and complex components and thermal error (TE) significantly affects the machining accuracy of PMTs. The TE compensation is an effective way to reduce its effect and improve the machining accuracy. But the real-time performance of the TE compensation system and the prediction performance and robustness of the TE model are weak. In this study, a multi-scale spatial–temporal interaction fusi...
