Biography

Chen Qiu is a PhD student supervised by Prof. Jian S Dai at the Centre for Robotic Research. Chen received the B.Sc. degree in spacecraft design and engineering from Beihang University in 2011, Beijing, China. His PhD project started late in the same year at King’s College London, which was funded by Kings-China Scholarship Council PhD Scholarship Programme. Currently Chen is working on EU FP7 Project TOMSY, as well as EU FP7 Project V-Feather.

Description of Research

Chen’s research interests focuses on mathematic theory and design of compliant mechanisms.

Compliant mechanism plays an important part in the design of industry and research robotics, successful applications include Remote-Center-Compliance device as well as flexible manipulators in surgical robots.

Compliant mechanism generates movements based on the deformation of flexible elements, the design of which includes both conceptual design and dimensional synthesis. Conceptual design focuses on the kinematic study of compliant mechanism. By treating it as equivalent rigid mechanism, mathematical theory such as screw theory can be applied to explore the kinematics of each flexible element, as well as the whole structure with various combinations of flexible elements.

Dimensional design focuses on the static and dynamic study of compliant mechanism, which bases on exploring the stiffness and compliance properties of developed structure according to specified task requirements.

Currently Chen conducts both the conceptual design and dimensional synthesis of compliant mechanisms within the frame work of screw theory, and the developed methods have been applied into the stiffness validation of origami-type cartons, compliance analysis and synthesis of ortho-planar spring, as well as synthesis of actuation space of parallel flexure mechanisms to minimize parasitic errors.
