This paper discusses some ways to achieve large tilting motions with PKM by resorting to articulated travelling plate. Different known options are firstly presented: remote actuation, hybrid architectures, redundancy, rotation amplification, and translation-to-rotation transformation. Starting from two of those features, the aim of this paper is to go one step further and to analyse various ways to obtain 4-dof robots which compare directly with commercially available Delta-like robots in terms of technology, workspace, and performance while avoiding the central, telescopic, RUPUR kinematic chain.
