Finn: Industrial automation data lacks behavioral diversity for general robotics

Chelsea Finn, Stanford professor and co-founder of Physical Intelligence, explains why scaling robotics data purely via repetitive industrial automation fails to produce generalizable models.

“So for example, we might look at data from industrial automation and you get tons and tons of data of robots doing tasks over and over again like this, but the sort of data isn't going to allow robots to go into disaster zones or to make a sandwich or to bag groceries. And so this massive scale doesn't have the diversity of behaviors that we need in order to solve this general problem.”

Opinion
Finn: Generalist robotics models may outperform purpose-built models
“And we think that this sort of generalist model may work better and be easier to use than purpose-built models, just like we've seen in the development of foundation, foundation models for language and other applications.”

Insight
Finn: Scale is necessary but not sufficient for open-world robotics models
“And so I think the lesson here is that scale is necessary for developing these models that can generalize in open world conditions, but they're subordinate to actually solving the problem. So you need scale, but it's not sufficient for the entire problem.”

Finn: Diverse Home Training Matches Custom Target-Environment Performance
“And we find that if we actually increase the amount of homes, the amount of locations that are represented in the data, The performance increases, which is great. And it actually gets to the same level of performance as if we train on data from that target env…”

Finn: Frontier models struggle with visual understanding for robotics
“In general, we found that these frontier models generally struggle with visual understanding as it pertains to robotics. Which makes sense because in general, these models aren't kind of really targeting, ah, many physical applications and have very little dat…”

Chelsea Finn: Real robot data cannot be replaced by synthetic data
“I think that at the end of the day, there's going to be no replacement for real data. And so we're like large amounts of real robot data. It's going to be a necessary component of any like system that's going to work in a generalizable way.”

Finn: Physical Intelligence is building a general-purpose model for all robots
“And in particular, we're trying to develop a general purpose model that can enable any robot to do any task in any environment.”
