Welcome to the Perception, Action, & Learning research group at UPenn (PennPAL). We simultaneously push the limits of what can be achieved using today’s prevalent principles in robot learning (“exploit”), and ask foundational questions in robotics towards building better design principles for efficient and minimalist robots in the future (“explore”). As examples of “exploit”, we have trained quadruped robots to perform circus tricks on yoga balls and robot arms to perform household tasks in entirely unseen scenes with unseen objects. As examples of “explore”, we are studying the sensory requirements of robot learners: what sensors do they need and when during training and task execution do they need them? We are motivated in all this work by the grand goal of building general-purpose robots that can help humans in our homes, offices, hospitals, farms, and more.

Note: A more complete research statement, written in August 2025, is here.
