Review of design solutions for manipulators and main areas of their application [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2021
Manipulators are multi-part constructions whose members are connected by joints. The most common kinematic structure is the series structure. The effector at the end of the structure is a process head or a gripper.

Suppression of rotating machine shaft-line torsional vibrations by a driving asynchronous motor using two advanced control methods [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2023
Many industrial rotating machines driven by asynchronous motors are often affected by detrimental torsional vibrations. In this paper, a method of attenuation of torsional vibrations in such objects is proposed.
