||Whenever two humans physically interact with each other, like during dancing Tango, their movements are determined by complex mechanical and control interplays between the motion and forces generated by each individual. Understanding these interplays are essential for the development of future robots in rehabilitation, biomedical devices and tele-operation systems so as to ensure that the interacting human is comfortable with the interacting robot, feels safe with them and benefits physically and psychologically from them. However, this is not a trivial task because human interactions change not only with individual body dynamics and control but change also with cognition, age and disease. The reason we feel comfortable when interacting with another human is because the other human can understand our behavior in all these aspects and respond accordingly – my research aims to develop similar abilities in future robots. Through integrated research in robotics, bio-mechanics, motor psychophysics, control and social neuroscience, I aim for a comprehensive understanding of human-robot interactions and develop human like interaction abilities in robots. In this talk I will introduce my work and present an example of a human interaction experiment to exhibit how mechanics, engineering, robotics and neuroscience can be combined together to understand human behavioral dynamics and in turn be utilized to develop better design and behavior in robots.
