Talk Title

Interaction between Feedback and Artificial Intelligence in High Levels of Automation

Abstract

Driverless cars, unmanned aircraft, fully automated mining in deep ground/sea, and healthcare robots looking after elder and disabled people — these are hot words we are seeing in the media, and discussed and debated at home and pubs. There is a huge aspiration about future highly automated society. But are we ready for that? Are they safe? This talk will discuss the limits of the current control theory and the lack of understanding of the interactions between different parts involved in robotics and autonomous such as perception, decision making/planning, uncertainty, environment, and system dynamics. Quite often the role of feedback is overlooked in the high levels of functions in dealing with events and uncertainty arising in an operational environment. It argues that autonomous control theory, as opposite to current automatic control theory, shall be developed to understand the role of feedback in highly automated systems. To achieve this goal, a close collaboration with computer science (e.g. artificial intelligence, machine learning, computation) and other disciplines is essential. A goal-oriented control system (GOCS) architecture is proposed to enable moving from how to perform a certain task to what a control system needs to perform so increase the levels of automation. The journey of the application of the EPSRC Fellowship will be briefly shared.

Talk Title

Study on Human Centred Robotics for EPSRC Fellowship Application

Abstract

Expressing, learning and reusing skills as modularized ones can strengthen the generalization ability of skills and reusability. Human-robot shared control combines the advantages of both human and robot. This talk will introduce my research in the field of robot skill learning and human-robot shared control. I used control theory to model the control mechanism of motor neurons to assist us developing human-like robot controllers so that the robot can realize variable impedance control to adaptively physically-interact with the changing environment. I further proposed a multi-task impedance control and impedance learning method used on a human-like manipulator with redundant degrees of freedom to achieve compliant human-robot interaction motor control. Learning from human demonstration methods are generally used to efficiently transfer modularized skills to robots using multi-modal information such as surface electromyography signals and contact forces, enhancing the effectiveness of skill reproduction in different situations. I have also developed an enhanced neural-network shared control system for teleoperation, which uses the redundancy of joint space to avoid collisions automatically. The operator does not need to pay attention to possible collisions during manipulation.

Furthermore, this talk will also introduce my application of EPSRC Innovation Fellowship, by applying the abovementioned techniques to flexible manufacturing. Typically, reprogramming and operating robots for production purposes can pose significant challenges for businesses, which could be potential barriers to automation and corporate expansion. I proposed to address these issues by increasing flexibility of robot operation based on human robot interaction.

Talk Title

Multidomain Vibration-Absorber Synthesis: Fellowship Application and Project Progress

Abstract

In this talk, I will first share my fellowship application experience - this includes proposal drafting, presentation and interview preparation. Each aspect will be linked with the awarded EPSRC fellowship on ‘Multidomain Vibration-Absorber Design’. In the second part of this talk, I will introduce the up-to-date project progress. Traditional vibration-absorber design approaches rely on introducing specific modifications to existing designs – this leaves huge performance possibilities unexplored. The developed synthesis-based methodology enables optimum designs to be constructed considering components from the mechanical, hydraulic, pneumatic, and electrical domains. The significant performance advantages will then be demonstrated for multiple mechanical systems, for both vibration suppression and passive-active-combined motion control purposes.
