Haptic Interaction with a Guide Robot in Zero Visibility

Abstract

DeclarationI hereby declare that this thesis embodies the results of my own work done as a part of EPSRC funded REINS project and that it has not been submitted anywhere for any award apart from that of Doctor of Philosophy at Sheffield Hallam University I have made acknowledgement of the work of others and have made reference to work carried out in collaboration with other people. ……………………………………………..

The potential of robot swarms for search and rescue has been shown by the Guardians project (EU, 2006(EU, -2010; however the project also showed the problem of human robot interaction in smoky (non-visibility) and noisy conditions. The REINS project (UK, 2011(UK, -2015 focused on human robot interaction in such conditions. This research is a body of work (done as a part of the REINS project) which investigates the haptic interaction of a person with a guide robot in zero visibility. The thesis firstly reflects upon real world scenarios where people make use of the haptic sense to interact in zero visibility (such as interaction among firefighters and symbiotic relationship between visually impaired people and guide dogs). In addition, it reflects on the sensitivity and trainability of the haptic sense, to be used for the interaction. The thesis presents an analysis and evaluation of the design of a physical interface (designed by the consortium of the REINS project) connecting the human and the robotic guide in poor visibility conditions. Finally, it lays a foundation for the design of test cases to evaluate human robot haptic interaction, taking into consideration the two aspects of the interaction, namely locomotion guidance and environmental exploration. AbstractI would like to start by offering huge thanks to my primary academic supervisor Prof. Jacques Penders. His patience, support and encouragement has helped me through the undulating emotional process of academic research and writing. With his guidance, I have achieved many great feats, for that I am eternally grateful. I also would like to thank my second supervisor Dr. Peter Jones for his comments and support that gave my work an interdisciplinary focus.
