On Building General-Purpose Home Robots

Speaker: Lerrel Pinto

Location: Off-Campus, Room Flatiron Institute

The concept of a “generalist machine” in homes — a domestic assistant that can adapt and learn from our needs, all while remaining cost-effective — has long been a goal in robotics that has been steadily pursued for decades. In this talk, I will present our recent efforts towards building such capable home robots. First, I will discuss how large, pretrained vision-language models can induce strong priors for mobile manipulation tasks like pick-and-drop. But pretrained models can only take us so far. To scale beyond basic picking, we will need systems and algorithms to rapidly learn new skills. This requires creating new tools to collect data, improving representations of the visual world, and enabling trial-and-error learning during deployment. While much of the work presented focuses on two-fingered hands, I will briefly introduce learning approaches for multi-fingered hands which support more dexterous behaviors and rich touch sensing combined with vision. Finally, I will outline unsolved problems that were not obvious initially, which, when solved, will bring us closer to general-purpose home robots.
