The Lex Fridman Podcast – #374 – Robert Playter: Boston Dynamics CEO on Humanoid and Legged Robotics

Intro

In this episode of “The Lex Fridman Podcast,” Lex Fridman interviews Robert Playter, the CEO of Boston Dynamics. Boston Dynamics is a renowned robotics company known for creating elegant and dexterous robots, such as the humanoid robot Atlas and the robot dog Spot. Robert Playter has been with Boston Dynamics from the beginning, including its roots at MIT, where he received his PhD in aeronautical engineering and wrote his thesis on robot gymnastics.

Main Takeaways

Robotics Development and Failure

• Boston Dynamics’ robots go through a lot of failure upon failure in the early and middle stages of development before they work properly.
• Breaking and repairing robots is a core principle that lets you be fearless in your work.
• Learning to make your own parts can be enabling and freeing.
• Developing scientific principles is important in robotics.

Motion and Elegance in Robotics

• Robert Playter, a robotics expert, was fascinated by movement and gymnastics, which led him to explore robotics at MIT.
• Pursuing interests and curiosity is a lasting lesson in robotics and AI.
• Efficiency and letting the body do what it wants to do is important in robotics.
• There is a magic to robotics that brings happiness to roboticists and makes them identify with their work.

Challenges in Humanoid Robotics

• Humanoid robots require intuition and art in addition to science.
• Getting the physics right can make the robot more stable and efficient.
• Delivering natural-looking walking in humanoid robots is surprisingly hard to achieve.
• The goal is to have a natural-looking gait, with heel strike first before rolling onto the toes.

Industrial Applications and Future of Robotics

• Boston Dynamics’ robots are being used for industrial monitoring to prevent expensive production losses.
• Boston Dynamics is developing a simpler robot focused on monitoring factory health.
• The hard problem in the next 10 years is getting a mobile robot to do useful manipulation.
• Boston Dynamics is focused on creating a low-cost humanoid robot that can perform general use cases.

Ethical Considerations and Future of Social Robotics

• People tend to attribute feelings and intelligence to robots that they don’t actually have.
• The future of social robotics may include generative AI that can create meaningful conversations and shared memories, leading to deeper connections and friendships.
• Boston Dynamics plans to engage with lawmakers and regulators to determine rules around the use of this technology and help force the issue.
• The connection between human and robot has magic and potential for profit, but ethical considerations must be addressed.
