Biography
Dr.?Xianwen?Kong?is?an?Associate?Professor?at?Heriot-Watt?University,?UK,?and?a?member?of?the?Edinburgh?Centre?for?Robotics—a?joint?initiative?between?Heriot-Watt?University?and?the?University?of?Edinburgh.?His?research?focuses?on?mechanisms?and?robotics,?with?particular?emphasis?on?the?creative?design?of?parallel?mechanisms?and?their?applications?in?advanced?manufacturing?and?renewable?energy.
Dr.?Kong?has?authored?or?co-authored?a?monograph?(with?Prof.?C.?Gosselin)?published?by?Springer,?two?U.S.?patents,?and?more?than?200?papers?in?leading?journals?and?conference?proceedings.?His?monograph?has?been?translated?into?Russian?by?FIZMATLIT?–?Nauka?Publishers?and?into?Chinese?by?China?Machine?Press?in?2012?and?2013,?respectively.
He?currently?serves?as?an?Associate?Editor?for?Mechanism?and?Machine?Theory?and?sits?on?the?editorial?board?of?the?Chinese?Journal?of?Mechanical?Engineering.?Previously,?he?was?an?Associate?Editor?for?the?ASME?Journal?of?Mechanisms?and?Robotics,?Mechanical?Sciences,?and?IEEE?Robotics?and?Automation?Letters.?From?2010?to?2022,?he?was?an?elected?member?of?the?ASME?Technical?Committee?on?Mechanisms?and?Robotics.
Dr.?Kong’s?contributions?have?been?recognized?with?several?prestigious?awards,?including?the?2012?Freudenstein/General?Motors?Young?Investigator?Award,?the?2020?A.T.?Yang?Memorial?Award?in?Theoretical?Kinematics,?and?the?2024?ASME?Leonardo?da?Vinci?Award.
Abstract
Parallel?mechanisms?have?been?a?focal?point?of?research?for?over?three?decades,?driven?by?demands?for?high?precision?and?large?payload?capacity.?Since?2007,?the?field?has?progressed?from?single-mode?designs?to?multi-mode?configurations,?enabling?mechanisms?to?adapt?seamlessly?to?changing?production?requirements?and?environmental?conditions.?Multi-mode?parallel?mechanisms?reconfigure?between?multiple?operational?modes?without?disassembly?and?with?minimal?actuators.?A?single?multi-mode?mechanism?can?replace?two?or?more?conventional?designs,?significantly?reducing?changeover?time.?This?talk?begins?with?an?overview?of?the?creative?design?of?conventional?parallel?mechanisms,?followed?by?the?introduction?of?a?virtual-chain?approach?for?innovative?design.?It?then?presents?a?systematic?construction?method?for?developing?multi-mode?parallel?mechanisms.?Finally,?the?presentation?explores?reconfiguration?analysis?using?quaternions?and?advanced?tools?from?computer?algebraic?geometry,?providing?deeper?insights?into?the?kinematic?behaviour?of?multi-mode?parallel?mechanisms.
