Cartesian Aerial Manipulator with Compliant Arm
Applied Sciences, 2021 This paper presents an aerial manipulation robot consisting of a hexa-rotor equipped with a 2-DOF (degree of freedom) Cartesian base (XY–axes) that supports a 1-DOF compliant joint arm that integrates a gripper and an elastic linear force sensor.

A study of commercial vehicle brake judder transmission using multi-body dynamic analysis [PDF]
, 2007 YesBraking-induced forced vibration, known as brake judder in road vehicles, causes dissatisfaction to drivers and passengers and also damage and possible early failure in components and systems. In this paper, the transmission of judder vibration from

Synthesis of clearance for a kinematic pair to prevent an overconstrained linkage from becoming stuck [PDF]
Mechanical Sciences, 2023 Mechanisms are prone to stuttering or even jamming due to the deformation of components, especially for overconstrained linkages for which geometric conditions must be strictly satisfied.

On the optimal design of parallel robots taking into account their deformations and natural frequencies [PDF]
, 2009 This paper discusses the utility of using simple stiffness and vibrations models, based on the Jacobian matrix of a manipulator and only the rigidity of the actuators, whenever its geometry is optimised. In many works, these simplified models are used to

Dynamic Responses of Planar Multilink Mechanism considering Mixed Clearances
Shock and Vibration, 2020 Translational and revolute joints are the main kinds of joints in planar multilink mechanisms. Translational and revolute clearance joints have great influence on dynamical responses of planar mechanisms.

Capturing Revolute Motion and Revolute Joint Parameters with Optical Tracking
IOP Conference Series: Materials Science and Engineering, 2017 Optical tracking of users and various technical systems are becoming more and more popular. It consists of analysing sequence of recorded images using video capturing devices and image processing algorithms. The returned data contains mainly point-clouds, coordinates of markers or coordinates of point of interest.
