Using a planar Force Feedback Interface for Improving Handling Comfort of hand-operated planar Mechanisms

In this study, the integration of haptic feedback system into the mechanism design process as a virtual pro-totype is shown to improve ergonomic properties of planar mechanisms. Integration of a haptic feedback system into the classical mechanism design and its benefits are presented. The planar force feedback inter-face “EFFI” developed at the Chair of Montage and Handling “MHT” Technische Universität Chemnitz is designed as a RPRPR (P: Prismatic, R: Revolute) type of a planar parallel robot and consists of two electromechanical cylinders (EMC), two load cells, a control unit, visualization unit and a programming interface. The main goal of the development of EFFI is the haptic rendering of non-linear guidance movements with high forces in large workspaces. Finally, different variants of a kitchen cupboard mechanism are simulated for validation and verification of proposed method and the haptic system. Furthermore, the users are tested the variants. Mechanism equipped with gas spring is perceived as pleasant by users.
