Questions & Answers

Q: How long did it take to develop natural-looking walking for Atlas?

Developing natural-looking walking for Atlas took around 10 to 15 years, with the team facing challenges in achieving the desired motion and ensuring the robot landed on extended legs while walking.

Q: What were some challenges in achieving good walking for Atlas?

The team had to deal with singular configurations, where the leg is fully extended and can't move further in one direction, making it more difficult to calculate torques and positions accurately. Simplifying the complex physics of the human body into a mathematical model also posed challenges.

Q: Why is under actuation a challenge in humanoid locomotion?

Under actuation means that the robot cannot be pushed in any direction at will, as it relies on the mediation of external forces through its feet. This poses a challenge for achieving natural movement, as the robot needs to compensate for the lack of external forces continually.

Q: How does the size and weight of Atlas impact its balance and locomotion abilities?

The large upper body and heavy legs of Atlas make it more challenging to maintain balance and perform tasks involving manipulating objects. The inertia of the upper body and the additional weight of objects carried by the robot increase the complexity of its motions.

Summary & Key Takeaways

• Developing natural-looking walking for humanoid robot Atlas took around 10 to 15 years, with the team facing difficulties in achieving the desired motion and getting the robot to walk on extended legs.

• The challenge of designing good walking involved dealing with singular configurations and simplifying the complex physics of the human body into a subsystem that can be described mathematically.
