Abstract : 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 propose two ideas: (1) It might be indeed possible to obtain a 4-dof design which compares directly with commercially available Delta-based robots (e.g. the FlexPicker, an ABB Robotics equipment) in terms of technology, workspace, and performance while avoiding the RUPUR kinematic chain. (2) It might be possible to design a 5-dof machine with large tilting angle about two axes.
