Associate Professor Department of Mechanical and Energy Engineering

Actuators are the primary basis in machines. They fundamentally determine the functions of machines and potentially affect their applications, and therefore, promote symbolic social progress (e.g., steam engines for the age of steam and electric motors for the age of electricity). Nowadays, however, the weakness and inadequacy of vastly used electromagnetic motors are impeding the technology progress in at least three significant fields: 1) for medical robots, actuators possessing satisfactory performances, e.g., compact size, high accuracy, and large stroke, remain to be developed; 2) bioinspired robots, particularly insect-inspired ones that limit by current actuators, are still not comparable to their natural counterparts regarding agility, robustness, and strength; 3) humanoid robots with conventional motors are not friendly enough to human collaborators, and soft, powerful, efficient, and accurately controllable actuators are highly desired.

To fundamentally address these problems, we have been exploring new approaches by rethinking basic principles and structures of actuators, and hence, implementing novel actuators distinguished from the conventional ones. Electrostatic actuation has drawn our vital interests due to its favorable features such as scalability, flexibility, lightweight, and low profile. We implemented a series of electrostatic film actuators and, by exploiting them, developed various robots with unique features (e.g., ultra-thin flexible climbing robots). We have also studied other actuation methods, such as flexible ionic polymer-metal composites for dexterous manipulators and an explosive actuator with a considerably high force-to-weight ratio for insect-scale water-air hybrid flying robots. In our future work, we will continue with this research methodology to implement more desirable novel actuators by exploring the basic physic principles and utilize them to build distinctive and valuable robots.

Personal Profile

Dr. Hongqiang Wang joined the Department of Mechanical and Energy Engineering at Southern University of Science and Technology as an Assistant Professor in September 2018. He received his Doctor degree from the University of Tokyo, Japan, in 2015. After graduation, he became a Research Fellow supervised by Prof. Hongliang Ren in the Department of Biomedical Engineering and SINAPSE, National University of Singapore, Singapore, working on flexible manipulators. From 2015 to 2018, he worked as a Postdoctoral Researcher in the School of Engineering and Applied Sciences and Wyss Institute, Harvard University, Cambridge, MA, USA. The main results include: 1) the world's thinnest flexible climbing robot; 2) millimeter-scale ultra-thin, long-stroke electrostatic motor; 3) bee flying robot that can freely cross the water-air interface (reported by BBC, Forbes Radio, Science News, and many other media).

1.Advanced actuation for robots.This course introduces to students the basic structure, principle and working characteristics of common and cutting-edge actuators in robotics, including electromagnetic motor, soft pneumatic actuator, hydraulic driver, piezoelectric motor, electrostatic actuator, shape memory alloy, ion-exchange polymer metal composite (IPMC) and dielectric elastomer, etc. This course committed to educating students with knowledge of the driving technologies mentioned above, to design and analyse basic actuators, to further master the calculation methods of the key parameters of common actuators, and finally, to select the appropriate actuators in the process of robot design. This course also aims to foster the capability of innovation and academic writing and presentation, by develop new actuators from the basic principles.

2.Fundamentals of Machine Design.The primary objective of this course is to give an overall introduction to the theories of mechanisms and principles of machine design. In the first part, the kinematic and kinetic analysis and design of mechanisms will be introduced to provide the students with the ability to conduct analysis and design of some common mechanisms. The second part of this course is focusing on generally used machine elements and mechanical drives to cultivate the students with the ability to correctly select the machine elements and to conduct maintenance of mechanical drives. Moreover, a project based workshop will be conducted to facilitate the understanding of the theories, principles, and mechanisms.
