Space Symposium First Prize of Wiley Poster Award, etc. 1. AS A WORLD-RENOWNED EXPERT IN SPACE ROBOTICS, CAN YOU BRIEFLY INTRODUCE YOUR RESEARCH DIRECTION AND CONTENT? I specialize in

R&D in robotic sensing, perception, machine learning, visual navigation, and bionic mechanisms, as well as their applications in the extreme environments for sectors like the space,

nuclear, and utility. I have international research projects funded by the European Space Agency, UK Space Agency, European Commission, UK Research Innovation, Royal Academy of Engineering,

and various industrial companies. I have also been involved in real-life space mission development, such as ESA’s ExoMars, Proba3 and VMMO, UK’s MoonLITE/MoonRaker, or collaborating with the

Chinese Academy of Sciences on deep data analysis collected by the Chang’E 3 lunar rover. 2. WHAT IS THE CURRENT FOCUS OF YOUR RESEARCH? WHAT PROBLEMS ARE YOU WORKING ON? My current

research focus on addressing challenges in spacecraft autonomy in-orbit or extraterrestrial bodies where the spacecraft are required to navigate and operate autonomously. For orbital robots,

such as those used for in-orbit servicing or removal of space debris, need to be immune to sensor noise and uncertainties in space to achieve autonomous navigation capabilities. There are

further challenges due to limitations of the spacecraft hardware since the onboard computer needs to be radiation hardened. Therefore, the computational speed is relatively slow, which

requires the intelligent algorithm of autonomous navigation to be low in computational complexity. To tackle these technical challenges, we have developed intelligent algorithms for spatial

navigation using only monocular camera sensors, and methods for robotic hand grasping of cooperative/non-cooperative objects based on sparse point cloud sensing. For planetary robots such as

for Mars, the robots need to deal with varying surface features on Mars, from rugged terrain to loose sand. There are also interesting features inside the Martian regolith that requires

drilling and sampling to study. To address these needs, we have developed a planetary sampling rover using principle of bionics. The rover can perform complex but energy-efficient locomotion

such as crawling, climbing, and burrowing. The drilling technique is inspired by wasp ovipositor hence the robotic prototype is developed in low mass and size hence suitable to achieve

low-energy drilling and sampling in low gravity, such as Moon, Mars, and asteroids. 3. THE UNITED NATIONS OFFICE FOR OUTER SPACE AFFAIRS (UNOOSA) HAS APPOINTED YOU AS A CLASS OF 2021 MENTOR

FOR THE SPACE4WOMEN PROJECT, WHICH AIMS TO PROMOTE ACTIVE AND EQUAL ROLES FOR WOMEN IN SPACE SCIENCE AND TECHNOLOGY, INNOVATION AND EXPLORATION, WHY DID YOU PARTICIPATE IN THIS INITIATIVE?

HOW DO YOU FEEL ABOUT IT? I am passionate and committed in supporting and mentoring female students and young researchers through universities and different foundations, and aim to

contribute my mentoring experience to the Space4Women program too. As a Space4Women mentor, I act as an ambassador to help implement the vision of the Space4Women by actively encouraging and

empowering women in education and careers of Science, Technology, Engineering, and Mathematics (STEM). In addition, I carry out public engagement and outreach activities to promote

Space4Women through a series of school visits, presentations, media interviews, science fairs, and festivals. 4. YOU ARE THE EDITOR-IN-CHIEF OF THE _JOURNAL OF FIELD ROBOTICS_, A TOP JOURNAL

IN THE FIELD OF ROBOTICS. WHAT ARE THE MAIN FEATURES OF THIS JOURNAL? WHAT ARE YOUR EXPERIENCES AND FEELINGS AS EDITOR-IN-CHIEF? _Journal of Field Robotics_ (JFR) is an international

academic publication focusing on “Field Robotics”. It has a history of more than 15 years and is recognized as a Q1 journal in computer and engineering-related disciplines. Field robots

mainly refer to robots working in unstructured and dynamic environments, involving a wide range of industrial applications, including construction, forestry, agriculture, mining, nuclear

energy, submarine, smart highway, search and rescue, military, and aerospace. JFR publishes papers with theoretical foundation and practical validation. We encourage authors to clearly

articulate the theoretical rationale of the scientific claims and demonstrate real-world applications with experimental data and validation. We aim to report not only the authors’ scientific

work, but also the lessons learnt gained from practical field trials. As the Editor-in-Chief of JFR, my goal is to serve all the relevant scientific and technological communities over the

globe. Our editorial team is committed to discovering and publishing high-quality academic results and papers in a timely manner through a rigorous peer-review system. We actively maintain

contacts with relevant academia and industry to influence and help promote rapid development of the field of robotics, which also includes helping to promote Diversity, Equality, and

Inclusion in related research fields and industries (such as promoting gender equality). 5. YOU HAVE TAKEN PART IN THE LIGHT CONFERENCE HOSTED BY _LIGHT: SCIENCE & APPLICATIONS_ (LIGHT),

WHAT WAS YOUR EXPERIENCE? WHAT ADVICE DO YOU HAVE FOR _LIGHT_? I had the pleasure to have participated in the Light Conference organized by _Light: Science & Applications_ as a

conference co-chair. I was very impressed by the sessions I attended. The conference featured keynotes by international leading experts and facilitated technical discussions within the

community. On the 10th anniversary of the publication of _Light_, I wish the journal continues to maintain a high level of academic standard and provide publication opportunities and

communication vehicle for the relevant scientific and industrial community. As an internationally renowned journal, _Light_ can serve as a good platform to help facilitate exchanges of

scientists and industrialists in the sector, as well as the wider international cooperation. 6. YOU ARE THE FOUNDING DIRECTOR OF THE AUTONOMOUS ROBOTICS LABORATORY (STAR LAB) AT THE SURREY

SPACE CENTRE, UNIVERSITY OF SURREY, UK. WHAT DIFFICULTIES DID YOU ENCOUNTER IN THE EARLY DAYS OF THE LAB? Challenges on creating and leading a research lab are ongoing issues facing its

leaders. In the start-up period, the main challenge is to establish scientific priorities and to develop our unique research identity or brand by striving for innovation and outstanding

scientific insights. Following from there, the challenge is around consolidating research directions and scientific philosophies or approaches to help produce theoretical findings and

practical verification results. It is also very challenging to continue to grow/sustain the team, attract/cultivate next generations of potential researchers, and maintain

high-quality/quantity outputs. 7. YOU WON THE FIRST PRIZE OF THE 14TH “CHINA-UK ENTREPRENEURSHIP COMPETITION”. HOW DO YOU VIEW THE RELATIONSHIP BETWEEN SCIENTIFIC RESEARCH AND INDUSTRY?

Scientific research and industrialization represent different stages of maturity in science and technology. The scientific research stage usually refers to Technological Readiness Level

(TRL) 1 to 4, which basically refers to the stage of exploration and validation of new knowledge. Industrialization refers to TRL 5 to 9, relating to the stage of more in-depth development

of technology and commercialization of products. Traditionally, the research carried out at the university campuses corresponds to low TRL. With the booming of high-tech and deep-tech

sectors, many university-oriented research work becomes more suitable for commercialization and industrialization. This is one of the reasons why we participated in the Entrepreneurship

Competition and won the award given our expertise. 8. AS A DOCTORAL SUPERVISOR, YOU HAVE TRAINED MANY STUDENTS. WHAT ABILITIES DO YOU MOST WANT YOUR STUDENTS TO DEVELOP? WHAT DO YOU EXPECT

FROM THE STUDENTS? In PhD supervision, I pay great attention in help developing students’ scientific rigor and integrity. It is very important to possess an honest and respectful attitude

towards science. In the journey of scientific research, one should aim to be rigorous, creative, open-minded, resourceful and supportive to peers, grateful, and responsible to the society.

9. YOU ONCE SAID, “WHEN I WAS A KID, I WAS VERY INTO ENGINEERING. I LIKE TO DO THINGS MYSELF. I WAS CURIOUS ABOUT ALL THINGS MACHINE.” HOW DID THAT PASSION FOR MACHINES AND ENGINEERING

AFFECT YOUR CAREER CHOICE? My childhood interests or innate love for technology had a huge impact on my career choice and continued development. This allows me to choose a career of dream

and interests. Especially when encountering difficulties, I often feel more empowered and confident to overcome obstacles, and rarely spend time complaining, self-pity, or put yourself in a

negative state of mind. 10. YOU HAVE WON MANY INTERNATIONAL AWARDS. IN 2019, YOU WERE AWARDED THE “MULAN AWARD” FOR YOUR CONTRIBUTIONS TO SCIENCE, TECHNOLOGY, AND ENGINEERING. WHAT DO THESE

AWARDS MEAN TO YOU? It is an honor and a privilege to be recognized by an important and essential organization as the Mulan Foundation. I feel very strongly that women of all nationalities

play a critical role in helping to progress and improve their professions, their communities, and the world and we must do all we can to recognize and lift them up. 11. ON INTERNATIONAL

WOMEN’S DAY IN 2021, YOU PARTICIPATED IN AN INTERVIEW WITH WILEY AND SENT HOLIDAY WISHES. WHAT DO YOU THINK ARE THE ADVANTAGES OF WOMEN IN SCIENTIFIC RESEARCH? I am a firm believer in the

principles of “Equality, Diversity, Inclusion (EDI)” and the importance of EDI in the field of research. Everyone deserves equal opportunities to pursuit scientific research. People

regardless of gender can potentially play important roles when they demonstrate required scientific abilities, commitments, and sense of responsibilities. I think women are the same as men

in front of science, and neither side has unique advantages over the other. 12. CAN YOU NAME ONE IMPORTANT TURNING POINT IN YOUR LIFE PLEASE? Take career as an example, shifting my research

focus to space robotic applications is an importance turning point. This happened nearly 20 years ago by chance, when project opportunities arose from the space industry to investigate AI

robotics for future space applications. I took the opportunity and made a step change in my career direction and priority and never looked back since then. 13. NAME ONE SCIENTIST WHO YOU

ADMIRE THE MOST, AND TELL US WHY? My role models are two Nobel Prize winning female scientists, Marie Curie and TU Youyou. I am inspired by their determination and work ethics in pursuing

scientific research, despite the limited resources and poor working conditions they had to work around at their time. 14. WHAT HOBBIES DO YOU HAVE? In my spare time, I like to explore and

learning new things too, from self-taught piano playing, handcraft making, to studying architecture, landscaping, and many more. 15. WHAT QUALITIES DO YOU THINK AN EXCELLENT SCIENTIFIC

RESEARCHER SHOULD POSSESS? For scientists, academic integrity, rigor, and freedom are very important. These qualities help retain the resilience and independence of academia to help enable

the scientific community conduct research responsibly and apply knowledge for sustainable development of the society. LIGHT SPECIAL CORRESPONDENT _Hui Wang is the Deputy Director of the
