Dikai Liu，Dr Dikai Liu is a distinguished professor and Co-Director of the Centre for Autonomous Systems (CAS) at the University of Technology Sydney (UTS), Australia. His main research interest is robotics with the focus on perception, motion planning, multi-robot collaboration, human-robot interaction and bio-inspired robotics. He initiated and developed the research themes of infrastructure robotics, robot teams and physical human-robot interaction in CAS. Besides conducting fundamental robotics research, he has also been transforming robotics research to real applications through leading the development of autonomous and assistive robots that can be practically deployed, including autonomous robots for steel bridge maintenance, bio-inspired climbing robots for inspection of complex steel structures, intelligent robotic co-worker for human-robot collaborative abrasive blasting, smart hoist for patient transfer, and Intervention-autonomous underwater robots (I-AUR) for underwater structure maintenance. Since 2005, his research has received a number of best paper and research/engineering excellence awards, including the 2016 Australian Engineering Excellence Awards (AEEA) and the 2015 Asia Pacific ICT Alliance (APICTA) Award. He is the recipient of many patents include USA and Australia patents. Some of his research outcomes has been translated to industry applications, including two autonomous bridge maintenance robots now in service at the Sydney Harbour Bridge and a bio-inspired climbing robot deployed for confined space inspection.。
