Questions & Answers

Q: What is the most amazing or beautiful robot that you've ever had the chance to work with?

I think it was Domo, which was made by one of my grad students, Aaron Edsinger. It is an upper torso humanoid robot with two arms, three-fingered hands, and various other features. It is mechanically gorgeous and looks like a work of art.

Q: Why was Domo amazing?

Domo is mechanically exquisite, with attention to detail in its design and build quality. It is aesthetically pleasing and visually striking. It is a testament to the engineering skills and creativity of its creator, Aaron Edsinger.

Q: Is the face of a robot important in terms of beauty?

When designing a robot, it is important to consider its appearance and the promises it makes for interaction. While a human-like face can enhance communication and engagement, it should not overpromise the capabilities of the robot. Domo's face consists only of eyeballs, which allow it to make eye contact and pay attention to people, without trying to mimic human features.

Q: When did you first fall in love with robotics?

I developed an interest in robotics at a young age. In the early 1960s, I came across books on electricity, giant brains, and robots, which sparked my curiosity. I started building circuits and learning about binary systems. Throughout my childhood, I continued to explore and build robots with the resources available to me.

Q: What were the robots you were building like?

I focused more on building the brains of robots rather than the mechanical aspects. I started with simple circuits and later built a learning system using chemical-based components. I used an ice cube tray as a cell and taught it to learn by applying voltage to create a copper bridge. It was a budget-conscious approach using what was available to me.

Q: Can machines think?

Yes, machines can think. Humans and other animals are machines, and we are capable of thinking. To deny this is a philosophical perspective that lacks a strong argument. However, building machines that can think and replicate human-like intelligence is a different and more challenging question.

Q: Are there fundamental differences between the computers described by Alan Turing and the biological computers in our brains?

Yes, there are significant differences between the two. Turing's concept of computation was based on a mechanical process, while the human brain is a biological computer that operates through complex neural networks. The way these systems process information and approach problem-solving is fundamentally different, but both can be considered forms of computation.

Q: What is computation, and how has it evolved over time?

Computation can be traced back to the early works of mathematicians like Napier and Kepler in the 17th century. Turing's 1936 paper defined modern computation by presenting a mechanical process that could compute arbitrary number sequences. Over time, the concept of computation expanded and evolved, with contributions from various mathematicians and scientists. Today, computation is a widely accepted framework for understanding and implementing computing systems.

Q: Is there a gap between the computer's ability to perform computation and the human brain's ability to create consciousness and intelligence?

There is indeed a gap between the current ability of computers to perform computation and the complexity of consciousness and intelligence in the human brain. While computers can simulate aspects of intelligence and perform specific tasks effectively, they fall short in replicating the full range of cognitive abilities and understanding. The gap lies in our limited understanding of how the brain works and our inability to replicate its intricacies.

Q: What are the hardest aspects of robotics?

Robotics encompasses many challenging aspects, and there are no easy parts. Perception, manipulation, reasoning, human-robot interaction, and the integration of different capabilities all pose significant difficulties. Each aspect requires deep understanding and expertise to achieve meaningful progress. Robotics is a multidisciplinary field that demands a range of skills and knowledge.

Q: If one category of robotics problems could be solved instantly, which one would give you the greatest pleasure?

It is difficult to choose just one category of robotics problems that would bring the most pleasure from solving. Each aspect of robotics presents unique challenges and opportunities. However, I am particularly interested in manipulation tasks, as they involve understanding perception, mechanics, reasoning, and the interaction between a robot and its environment.
